Product description

The Siemens 3WL1232-4CB62-4GA4 is a fixed-mounted, 3-pole circuit breaker in size 2, rated for 3200A at up to 690V AC (50/60Hz). It offers an excellent interrupting capacity (Icu) of 100kA at 500V and features rear horizontal connections. This breaker is equipped with the ETU 25 electronic overcurrent release with adjustable LSI (Long-time, Short-time, Instantaneous) protection (0.4-1 In), a motorized/manual operating mechanism with a spring-charging motor, and a shunt release (F1) for remote tripping.

This robust circuit breaker is designed for demanding industrial power distribution applications, providing reliable protection and operational flexibility. The inclusion of a shunt release allows for integration into safety interlock systems or remote emergency stop circuits.
