The TM210 trip unit is fixed thermal and magnetic; no adjustable long-time or short-time pickup, so coordination with downstream breakers depends on the inherent band. Breaking capacity spans 121 kA at 240 V down to 11.9 kA at 690 V. That's enough for most industrial service-entrance or feeder positions without a current-limiting upstream fuse. That's enough for remote status and a separate trip-indication signal back to the PLC or annunciator panel. No undervoltage release, no shunt trip, no communication module — it's a straight thermal-magnetic breaker with basic aux contacts. Width is 76.2 mm (roughly 3 inches per pole), depth 70 mm, height 130 mm — standard 3-pole MCCB footprint for the SENTRON 3VA platform. Front IP40 protects against tool contact in a closed panel; no washdown rating, so keep it inside the enclosure.","metaTitle":"Siemens 3VA1025-4ED32-0AH0 SENTRON MCCB, 25 A, 121 kA at 240","metaDescription":"Siemens SENTRON 3VA1025-4ED32-0AH0 molded case circuit breaker, 25 A rated, 121 kA breaking at 240 V.
