The Mitsubishi UVT-05SSB is a high-quality Under Voltage Trip (UVT) accessory designed for use with Mitsubishi’s world-class circuit breakers. This essential safety device automatically trips the associated circuit breaker when the control circuit voltage drops below a specified threshold, typically between 35% and 70% of the rated voltage. By doing so, it protects sensitive machinery and electrical systems from potential damage caused by under-voltage conditions. The UVT-05SSB also prevents the circuit breaker from being switched on until a stable and sufficient voltage is restored, ensuring safe and reliable operation. It is engineered for seamless integration with specific models in the Mitsubishi NF and NV series, offering a dependable solution for applications requiring robust voltage monitoring and protection.
