FAQ
What is the 12VEMP250KA mainly used for?
The 12VEMP250KA is designed to help protect 12VDC battery-powered electrical systems from damaging surge events. Its primary application is vehicle protection, but it can also be used on compatible 12VDC battery circuits in marine, RV, generator, emergency power, communications, and other low-voltage DC applications.
What voltage is the 12VEMP250KA designed for?
The 12VEMP250KA is designed for 12VDC electrical systems only. Do not use this device on AC power, 24VDC systems, or any voltage outside the product rating.
What does the 250KA rating mean?
The 250KA rating refers to the surge current capacity of the device. The 12VEMP250KA is designed to provide a higher level of surge protection than the MEMP12V, while offering a lower-cost option compared to the MAXEMP12V.
How is the 12VEMP250KA different from the MEMP12V and MAXEMP12V?
The 12VEMP250KA sits between the MEMP12V and MAXEMP12V in protection level. The MEMP12V has a 150KA surge current rating, the 12VEMP250KA has a 250KA surge current rating, and the MAXEMP12V has a 500KA surge current rating.
Does the 12VEMP250KA protect against EMP, CME, solar flare, and lightning-related surges?
Yes. The 12VEMP250KA is designed to help protect compatible 12VDC systems against normal surge events, indirect lightning-related surge activity, and EM-related surge events such as EMP, CME, and solar flare related electrical disturbances.
Where should the 12VEMP250KA be installed?
The 12VEMP250KA is recommended to be connected directly to the battery terminals for best protection. If battery installation is not possible, it may be connected to another suitable section of the 12VDC electrical circuit.
Can the 12VEMP250KA be used on vehicles?
Yes. Vehicles are the primary application for the 12VEMP250KA. It is designed to connect to a compatible 12VDC vehicle battery circuit to help protect the vehicle’s electrical system from damaging surge events.
Can the 12VEMP250KA be used on boats, RVs, generators, or other 12VDC battery systems?
Yes. The 12VEMP250KA may be used on compatible 12VDC battery circuits in marine, RV, generator, off-grid, communications, and emergency equipment applications when installed according to the product instructions and voltage rating.
How is the 12VEMP250KA wired?
The 12VEMP250KA has two wires. The red wire connects to the positive side of the 12VDC circuit, and the black wire connects to the negative side of the 12VDC circuit.
Does the 12VEMP250KA connect to chassis ground?
No. The 12VEMP250KA connects only to the positive and negative sides of the 12VDC electrical circuit. On a vehicle, the chassis is already connected to the negative battery terminal. Adding a third chassis ground wire could create a ground loop and cause electrical issues.
Is polarity important when installing the 12VEMP250KA?
Yes. The 12VEMP250KA is polarized. The red wire must be connected to positive, and the black wire must be connected to negative. Always verify polarity before connecting or energizing the circuit.
What do the indicator lights mean?
The 12VEMP250KA includes green and red indicator lights. Green means the surge protector is functioning correctly. Red means the surge protector needs to be replaced.
Does the 12VEMP250KA need a fuse or circuit breaker?
No additional fuse or circuit breaker is required specifically for the 12VEMP250KA because it connects in parallel with the electrical circuit and includes built-in overcurrent protection. Always make sure the vehicle or 12VDC electrical system has proper circuit protection for the overall installation.
Can the 12VEMP250KA be installed outdoors?
The 12VEMP250KA is waterproof and suitable for harsh environments, but it should not be submerged in water. Install it in a secure location where it will not be exposed to physical damage or improper use.
Can the 12VEMP250KA be submerged in water?
No. Do not submerge the 12VEMP250KA in water. Although the device is waterproof, it should be installed and used in a way that prevents submersion or damage.
Can the 12VEMP250KA be used on AC power?
No. The 12VEMP250KA is for 12VDC electrical systems only. Do not use this device on AC power.
Can the 12VEMP250KA be used on 24VDC systems?
No. The 12VEMP250KA is designed for 12VDC systems only. Do not use it on 24VDC systems or any voltage outside the product rating.
Can the 12VEMP250KA be opened or modified?
No. Do not open, modify, tamper with, or improperly use the 12VEMP250KA. If the device is damaged, improperly connected, or indicates replacement is needed, it should be replaced.
Who should install this product?
This product should be installed by someone familiar with 12VDC electrical systems, vehicle batteries, polarity, and the equipment being protected. When in doubt, consult a qualified technician, mechanic, marine technician, RV technician, or installer.
Does this product include a 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.
