The 3WL1225-2CB45-4GN4 Siemens is a withdrawable circuit breaker designed for robust performance and safety in electrical systems. This 4-pole circuit breaker, conforming to IEC standards, has a rated current (In) of 2500A and is suitable for applications up to 690V AC at 50/60Hz. It boasts a high ultimate short-circuit breaking capacity (Icu) of 66kA at 500V, ensuring reliable protection against overcurrents. The rear connection is horizontally oriented for convenient installation. Equipped with an ETU 25 LSI overcurrent release, it offers adjustable protection settings from 0.4 to 1 times the rated current. The circuit breaker features a motorized/manual operating mechanism with a spring charging motor, compatible with AC 50/60 Hz 208-240 V or 220-250 V DC. Activation is supported by AC 50/60 Hz 230 V and 220 V DC. It includes a 1st auxiliary release (Shunt release "F", F1) rated for 50/60 Hz 230 V AC/220 V DC with a 100% on-load factor, along with a 2nd auxiliary release ("R", F3) for undervoltage protection, which is instantaneous and rated for 208-240 V AC and 220-250 V DC. The breaker also provides 4 normally open (NO) and 4 normally closed (NC) auxiliary contacts for enhanced monitoring and control capabilities.
