It's built for line protection using a TM210 thermal-magnetic trip unit — fixed overload protection at Ir = 25 A and short-circuit pickup set at Ii = 12.8 × In. That fixed ratio means no field-adjustable magnetic trip; the breaker trips fast on hard faults, which simplifies coordination studies for the panel builder. For a 25 A feeder protecting a motor control center or distribution panel, that's serious headroom. The shunt trip (STL) operates on 220–250 V DC or 208–277 V AC, so you can remotely trip the breaker from an E-stop or fire alarm relay without running a separate control voltage. Two auxiliary switches (HQ) give you status feedback — one for the main contacts, one for the trip alarm — enough to light up a PLC input or a panel lamp without adding an external block. The shunt trip and auxiliary switches are factory-installed, so no field assembly of accessories. For a panel builder, that saves about 10 minutes per breaker on the bench.","metaTitle":"Siemens 3VA1025-4ED32-0KC0 Circuit Breaker, 25A, 36kA @ 415V","metaDescription":"Siemens 3VA1025-4ED32-0KC0 IEC frame 100 circuit breaker, 25A, 36kA breaking capacity @ 415V.
