Sensata RP-8A Thermal Protector Low Sensitivity 3 Wire for Dedicated Voltage

Identification & Application

The Sensata RP-8A is a low sensitivity thermal protector from the Sensata RP Series engineered for dedicated voltage overtemperature protection in recessed lighting and similar fixtures. It is an automatic resetting device that interrupts the circuit when internal temperatures reach a lower sensitivity trip point. The three-wire configuration supports connection in dedicated line voltage installations at the rated heater voltage. This protector is intended for internal mounting within non-IC recessed luminaires and compatible lighting assemblies where thermal protection is required by manufacturer specification and electrical code.
