CHINT OVT-X3 Overvoltage release

CHINT OVT-X3 Overvoltage release,
is designe to integrate with NXB-125 series circuit breakers,
providing automatic protection against abnormal overvoltage conditions.
Operating at AC 230V 50/60Hz, it detects voltage surges beyond the safe limit (280V ±5%) and triggers the breaker to disconnect the circuit.
Compact, reliable, and easy to install on TH35-7.5 DIN rails,
the OVT-X3 ensures enhance safety for residential and commercial power distribution systems.
