Three poles, TM210 thermal-magnetic release, and a breaking capacity that drops from 121 kA at 240 V to 76 kA at 415 V, then 53 kA at 440 V, and settles at 11.9 kA for both 500 V and 690 V — so the voltage class of your distribution bus determines which interrupting rating applies. ## Integration dimensions and mounting Footprint: 76.2 mm wide (3 in), 130 mm tall (5.1 in), 70 mm deep (2.8 in). ## Fault isolation and field service The TM210 overcurrent release is a fixed thermal-magnetic type — no interchangeable trip units, so the 25 A rating is baked in. The -40 °C floor matters for cold-start installations in unheated shelters or outdoor enclosures.","metaTitle":"Siemens 3VA1125-4ED36-0AA0 SENTRON MCCB, 25 A, 3-Pole, TM210","metaDescription":"Siemens 3VA1125-4ED36-0AA0 SENTRON molded case circuit breaker, 25 A rated continuous current, 3-pole, TM210 release, 121 kA at 240 V.
