Eaton LGU3630NN Industrial Molded Case Circuit Breaker

The Eaton LGU3630NN Industrial Molded Case Circuit Breaker is a heavy-duty overcurrent protection device for three-phase industrial power distribution. It is rated at 630 A and 600 V, configured as a 3-pole breaker with a 65 kA interrupting capacity, and it uses a LT340036 Trip Unit (W). This LGU-series MCCB provides protection for feeders and three-phase circuits where fault currents may be present, ensuring rapid isolation when faults arise. The 630 A rating denotes the maximum continuous current under normal operating conditions, while the 65 kA rating specifies the maximum fault current the breaker can interrupt at the rated voltage. The LGU3630NN is manufactured by Eaton, a long-standing supplier of molded case circuit breakers, and is designed for applications requiring overcurrent protection in industrial settings.
