It also carries a communication function, so it can report status or trip events to a higher-level system. The front face is IP40 rated, suitable for enclosed panel mounting. The 86 mm depth (3.39 in) leaves clearance for rear-connected busbars or cable ducts behind the mounting plate. The optional motor drive allows remote racking-in or -out without opening the door, useful for automated testing or emergency disconnect sequences. ## What the ETU560 release means for coordination That matters when you are coordinating downstream branch breakers: the short-time delay band lets you achieve selectivity up to the breaker's withstand rating, so a fault on a feeder does not take out the main. The ground-fault function monitors residual current via summation of the three phase conductors — set the pickup level per the installation's earth-leakage requirements. Maximum power loss is 0.6 W, negligible for panel heat-budget calculations.","metaTitle":"Siemens 3VA2125-5JQ32-0AA0 SENTRON MCCB, 25 A, 187 kA at 240","metaDescription":"Siemens 3VA2125-5JQ32-0AA0 SENTRON molded case circuit breaker, 25 A rated current, 187 kA breaking at 240 V. 3-pole, ETU560 release, communication capable.
