OVT-X1 Overvoltage Release

The OVT-X1 Overvoltage Release is an accessory designed to provide overvoltage protection for CHINT’s NXB-63 and NXB-40 circuit breakers. When the main circuit voltage exceeds 280V ±5%, the OVT-X1 automatically trips the connected circuit breaker, preventing damage to electrical systems. It operates reliably within 85%–110% of rated voltage (AC 240V, 50/60Hz), ensuring consistent performance. Compact, easy to mount on TH35-7.5 DIN rails, and durable with over 4000 operation cycles, it is ideal for residential and light commercial protection.
