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.
Ratings and what they mean for your panel
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 TM210 release is a fixed thermal-magnetic type — no interchangeable trip units, which simplifies ordering but means you pick the amp rating at purchase and it stays. 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. The IP40 front protection means it's sealed against tools and small wires but not against water — fine for indoor panels, not for washdown areas.
Mounting and integration
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. Operating temperature range is -25 °C to 70 °C, storage from -40 °C to 80 °C.
