Sensata RP-5A Thermal Protector Low Sensitivity 3 Wire for Dedicated Voltage

The Sensata RP-5A Thermal Protector is a low-sensitivity automatic-reset thermal protector designed to safeguard non-IC recessed lighting fixtures operating on dedicated 240V systems. Engineered to meet UL, CSA, and NEC requirements, the RP-5A monitors fixture temperatures and responds to overheating caused by insulation contact or abnormal operating conditions. When excessive heat is detected, the protector interrupts power to the fixture and automatically resets after cooling, providing continuous thermal protection while allowing the lighting fixture to resume normal operation.

Designed specifically for dedicated-voltage lighting applications, the RP-5A features a compact three-wire configuration with black, white, and gray leads. The gray and white wires form the 240V heater circuit, while the black and gray wires serve as the thermal protection circuit. Its compact cylindrical housing and spring-steel mounting clip provide quick installation into recessed lighting fixtures while delivering dependable long-term protection for dedicated-voltage ballast systems.

Built around Sensata's proven SB600 Series thermal protection technology, the RP-5A combines automatic-reset operation with low thermal sensitivity to minimize nuisance tripping while maintaining reliable protection against overheating. Its rugged construction and dependable performance make it an ideal replacement thermal protector for commercial, residential, and institutional recessed lighting applications.
