The SP240V50KA is often used for equipment-level protection on HVAC condensers, pumps, and dedicated equipment circuits. The SP240V65KA is a better fit for customers looking for an entry-level whole-house surge protector at the electrical panel.

Should I choose the SP240V65KA or a larger Bad Wolf model?

The SP240V65KA is a good entry-level choice for whole-house surge protection. Customers who want a higher surge current rating or a higher level of protection may want to consider the SP240V100KA, SP240V200KA, or SP240V400KA models.

What does the 65KA rating mean?

The 65KA rating refers to the surge current capacity of the device. It is designed to help protect connected electrical equipment from damaging surge events when properly installed on a compatible system.

Is this a Type 1 surge protective device?

Yes. The SP240V65KA is a Type 1 surge protective device, which allows it to be installed on the line side or load side of the service disconnect when installed in accordance with the product instructions and applicable electrical codes.

What does the status light mean?

The status light provides a visual indication of protection status. Green means the surge protector is functioning. If the light is off, the device should be replaced.
