The Siemens SENTRON 3VA1025-3ED32-0CA0 is a 3-pole molded case circuit breaker rated for 25 A continuous current at 40 °C, with a TM210 thermal-magnetic overcurrent release and an integrated undervoltage release (UVR). It delivers 75.6 kA breaking capacity at 240 V, 52.5 kA at 415 V, and 32 kA at 440 V — figures that cover most industrial distribution panels and motor branch circuits.
The 25 A continuous rating holds flat from 40 °C up to 50 °C, then derates gradually to 22.5 A at 70 °C — so in a warm enclosure you still get full current up to 50 °C without derating. The 75.6 kA at 240 V is the maximum short-circuit current the breaker can safely interrupt at that voltage; at 415 V it still handles 52.5 kA, enough for most 400 V distribution boards. The undervoltage release (UVR) is built in (auxiliary release design: undervoltage release), so if your safety circuit or emergency-stop chain drops control voltage, the breaker trips. No separate shunt trip needed for that function.
Dimensions are 70 mm deep, 76.2 mm wide, and 130 mm tall — a standard 3-pole MCCB footprint that fits Siemens SENTRON distribution boards and most DIN-rail adapters. The 3-pole design covers three-phase loads; no auxiliary contacts are included (auxiliary contact version: Without), so if you need remote status indication you'll add the separate 3VA9608-0BB24 auxiliary trip block.
