Cutler-Hammer C320MSR1L Undervoltage Release Module is a safety accessory with a 380–440 V operating range. When the voltage falls outside this range, the module releases to trip the circuit breaker, helping protect motors and equipment from damage during undervoltage conditions. Model C320MSR1L, this undervoltage release is part of Cutler-Hammer's line of protection devices and is suited for inclusion in industrial control panels and power distribution setups that rely on precise voltage protection.
