Siemens NGB2B060B U Molded Case Circuit Breaker

Siemens NGB2B060B U is a two-pole molded-case circuit breaker rated at 60 A and 480 V, part of Siemens’ NGB family of low-voltage MCCBs. It is intended for panelboard mounting to protect feeders and branch circuits in commercial and light-industrial power-distribution systems. The unit employs a thermal-magnetic trip mechanism and offers an interrupt rating of 14 kA (RMS) to clear faults on a 480 V distribution, helping prevent damage to wiring and equipment during short circuits or overloads. With its compact two-pole form factor, the NGB2B060B U provides simultaneous protection of both conductors in typical 2-wire or multiwire panel configurations, and it is designed for use in standard Siemens distribution panels where NGB MCCBs are specified. This model is suitable for installations requiring a 60 A device on a 480 V system, delivering reliable, predictable overcurrent protection in control and distribution panels where fast fault clearing is essential.
