UVTSA450-4SWRFSU05 MITSUBISHI

The UVTSA450-4SWRFSU05 from Mitsubishi is an undervoltage trip unit designed to protect electrical systems from damage caused by low voltage conditions. This device is compatible with AC voltage ranges of 100-120V, 200-240V, and 380-450V, offering versatility in various power environments. It features a time delay (TD) function, allowing for a brief period of undervoltage before tripping, preventing nuisance tripping due to momentary voltage dips. This model is configured for 4-pole circuit breakers, specifically the NF/DSN400AF and 630AF series. The undervoltage trip unit continuously monitors the voltage level and initiates a trip when the voltage falls below a predetermined threshold. This action disconnects the circuit, safeguarding connected equipment from potential harm. The UVTSA450-4SWRFSU05 enhances the reliability and safety of electrical systems by providing essential undervoltage protection. Its robust design and compatibility with established circuit breaker models make it a dependable choice for industrial and commercial applications. By preventing equipment damage and downtime, this undervoltage trip unit contributes to operational efficiency and cost savings. Its precise voltage monitoring and time delay functionality ensure optimal protection against undervoltage events.
