Circuit Breaker · Electrical Components & Switchgear
Designed to enhance electrical safety by providing overvoltage protection, the OVT-X1 Overvoltage Release works in conjunction with circuit breakers to safeguard against voltage surges. This device is specifically engineered to trip an NXB-63 series circuit breaker when the main circuit voltage reaches 280 volts, ensuring reliable operation within the range of 85% to 110% of its rated operation voltage of 240V at 50Hz or 60Hz. The OVT-X1 features a mechanical and electrical life of at least 4000 operation cycles, and it weighs just 0.05 kg. It can be easily installed with either the NXB-63 or NXB-40 series circuit breaker and mounted on a TH35-7.5 steel mounting rail. With dimensions of 79±1.40 mm in length and 43.5±0.31 mm in width, the OVT-X1 is compact and versatile, offering a robust solution for electrical protection systems.
