SP3P208VY 208Y/120V Three-Phase Wye Surge Protector
The Bad Wolf SP3P208VY is a high-capacity Type 1 surge protective device designed for 208Y/120V three-phase, 4-wire wye electrical systems. With a 260kA surge current rating, it provides surge protection for all three phases in commercial, industrial, generator, EV charging, agricultural, and other three-phase electrical applications.
Independent Protection Status for All Three Phases
The upgraded SP3P208VY features six individual LED status indicators — one green LED and one red LED for each phase. Each phase is monitored independently, allowing the protection status of Phase A, Phase B, and Phase C to be checked at a glance.
- Green LED: The surge protection circuitry for that phase is operating normally and the line is protected.
- Red LED: The surge protection circuitry for that phase has been damaged or compromised and that line is no longer protected.
Because each phase is monitored independently, the SP3P208VY may display three green LEDs during normal operation, three red LEDs if protection has been lost on all three phases, or a combination of green and red LEDs if protection has been lost on only one or two phases.
If any red phase-status LED is illuminated, the SPD should be replaced to restore complete three-phase surge protection.
Reversible Cover for Flexible Mounting
The phase-status indicators are positioned in the center of the enclosure so the front cover can be oriented for easier reading regardless of the horizontal mounting direction. If the installation causes the product labeling to appear upside down, the front cover can be removed and rotated 180 degrees so the label and status information remain upright and easy to read.
Always disconnect and verify power is off before removing or repositioning the cover.
Designed for 208Y/120V Three-Phase Wye Systems
A 208Y/120V three-phase wye system provides approximately 120V from each phase to neutral and 208V from phase to phase. This configuration is also commonly described as 208V three-phase, 4-wire or 208Y/120V.
- Phase-to-Neutral Voltage: 120V
- Phase-to-Phase Voltage: 208V
- Electrical Configuration: Three-phase, 4-wire wye
Built for Indoor or Outdoor Installations
The SP3P208VY is housed in a NEMA 4X enclosure suitable for indoor or outdoor installations and includes 36-inch wire leads with a 3/4-inch liquid-tight conduit connection for hardwired installation.

Installation
SP3P208VY Installation
Before Installation
Verify that the electrical system is a 208Y/120V three-phase, 4-wire wye system with equipment ground before installing the SP3P208VY.
- Phase-to-neutral voltage should be approximately 120V.
- Phase-to-phase voltage should be approximately 208V.
- Confirm that the electrical system and application are compatible with the ratings of the SP3P208VY.
- Disconnect power and verify that the installation area is de-energized before beginning work.
Type 1 Installation
The SP3P208VY is a Type 1 Surge Protective Device. Type 1 SPDs are suitable for installation on the line side or load side of the service disconnect when installed in an approved location and in accordance with applicable electrical codes and installation requirements.
For best surge protection performance, install the SPD as close as practical to the electrical equipment or panel being protected. Keep the SPD conductors as short and straight as practical and avoid unnecessary loops, coils, or sharp bends in the wiring.
Wiring Connections
Connect the SP3P208VY conductors to the corresponding electrical system conductors as shown on the product wiring label:
| Phase A | Black wire |
|---|---|
| Phase B | Red wire |
| Phase C | Blue wire |
| Neutral | White wire |
| Ground | Green wire |
The SP3P208VY includes approximately 36 inches of wire leads and a 3/4-inch liquid-tight conduit connection for hardwired installation.
Reversible Cover Orientation
The upgraded SP3P208VY places the Phase A, Phase B, and Phase C status indicators in the center of the enclosure. This allows the front cover to be repositioned when the SPD is mounted horizontally in the opposite direction.
If the product labeling appears upside down after mounting, with all power disconnected and verified off, remove the front cover, rotate it 180 degrees, and reinstall it securely. This allows the product label and phase-status information to remain upright and easy to read.
Verify Operation After Installation
After all wiring and mounting have been completed, restore power and check the Phase A, Phase B, and Phase C status indicators.
- Normal Operation: The green LED for each phase should be illuminated, indicating that the surge protection circuitry for that phase is operating normally.
- Protection Lost: A red LED indicates that the surge protection circuitry for that phase has been damaged or compromised and that phase is no longer protected.
During normal operation, the SP3P208VY should display three green phase-status LEDs. If any red LED is illuminated, the affected phase is not protected and the SPD should be replaced to restore complete three-phase surge protection.
Warranty
Bad Wolf surge protection devices include a 5-year product warranty.
Eligible products may also include connected equipment warranty coverage when properly installed and registered according to the warranty terms.

FAQ
What electrical system is the SP3P208VY designed for?
The SP3P208VY is designed for 208Y/120V three-phase, 4-wire wye electrical systems with equipment ground. In this system, voltage is approximately 120V from each phase to neutral and 208V from phase to phase.
Is the SP3P208VY a Type 1 or Type 2 surge protector?
The current SP3P208VY is a Type 1 Surge Protective Device. Type 1 SPDs are suitable for installation on the line side or load side of the service disconnect when installed in an approved location and in accordance with applicable electrical codes and installation requirements.
What do the green LEDs mean?
Each phase has its own green status LED. A green LED indicates that the surge protection circuitry for that phase is operating normally and the line is protected.
What does a red LED mean?
A red LED indicates that the surge protection circuitry for that phase has been damaged or compromised and that phase is no longer protected.
Can some phases show green while another phase shows red?
Yes. Each phase is monitored independently. The SP3P208VY may display all three green LEDs, all three red LEDs, or a combination of green and red LEDs depending on the condition of the surge protection circuitry for each phase.
What should I do if one or more red LEDs are illuminated?
If any red phase-status LED is illuminated, the affected phase is no longer protected. The SP3P208VY should be replaced to restore complete three-phase surge protection.
What should the LEDs look like during normal operation?
During normal operation, the SP3P208VY should display three green LEDs — one for Phase A, one for Phase B, and one for Phase C — with no red phase-status LEDs illuminated.
Why can the front cover be rotated 180 degrees?
The phase-status indicators are positioned in the center of the enclosure so the front cover can be rotated 180 degrees if the SPD is mounted horizontally in the opposite direction. This allows the product label and status information to remain upright and easy to read.
Can I rotate the cover while the SPD is energized?
No. Always disconnect power and verify that the installation is de-energized before removing or repositioning the front cover.
What are the SP3P208VY wiring colors?
- Phase A: Black
- Phase B: Red
- Phase C: Blue
- Neutral: White
- Ground: Green
Can the SP3P208VY be installed outdoors?
Yes. The SP3P208VY uses a NEMA 4X enclosure suitable for indoor or outdoor installations when properly installed.
What is the surge current rating of the SP3P208VY?
The SP3P208VY has a 260kA surge current rating.
Is the SP3P208VY made to order?
Yes. The SP3P208VY is built after the order is placed. Please allow approximately 3–5 business days for production before shipment.
