Pigtail Protectors for Service and Distribution Panels

PT2 Series models are housed in a compact, plastic, hermetically sealed

housing that ensures weatherproof protection for outdoor and indoor

installations. Color-coded wiring conforms to US and International standards

and convenient pigtail design makes installation flexible and easy.

Thermal disconnects and fusing for each MOV plus a sand-filled enclosure

permit benign end-of-life mode during sustained line overvoltage conditions,

thus eliminating smoke and fire damage to adjacent equipment.

Method of Operation

When a transient surge exceeds the normal system voltage, the PT2

Series device responds within nanoseconds and changes state from a

high-impedance open circuit to a low-impedance shunt (short circuit).

Connected in parallel with the facility’s loads, the PT2 Series device diverts

damaging current away from sensitive loads while simultaneously reducing

(clamping) the high transient voltage to harmless levels. Upon the end of

the transient event, the PT2 Series device automatically returns to its normal

operating condition without service interruption.
