That thermal curve matters if this breaker lands in a crowded enclosure or near a heat source; the 25 A nameplate is good for most standard panel environments, but you lose about 2.5 A at the top of the operating range. Breaking capacity is substantial: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 690 V. That 121 kA figure at 240 V covers high-fault utility feeds; the 75.6 kA at 415 V is typical for industrial distribution in IEC markets. The TM210 overcurrent release is a fixed thermal-magnetic unit — no interchangeable trip units, so what you order is what protects the circuit. That gives you status feedback for a PLC or annunciator without adding external relays. That 76.2 mm width is a standard 3-pole MCCB footprint — three 25.4 mm pole spacings — so it drops into existing SENTRON or comparable panel layouts without re-drilling. ## What to know about the shunt trip and aux contacts The integrated shunt trip (STL) is listed as design 3VA9688-0BL32 — that is the factory-fitted release, not a field-add kit. If you need undervoltage release or ground-fault monitoring, this variant does not carry them; those are separate order codes. The 2 aux + 1 alarm switch gives you one NO/NC pair per aux plus a dedicated alarm contact that changes state on trip, independent of handle position.","metaTitle":"Siemens 3VA1025-4ED32-0JH0 SENTRON MCCB, 25 A, 3-Pole, 121 k","metaDescription":"Siemens SENTRON 3VA1025-4ED32-0JH0 molded case circuit breaker, 25 A rated, 3-pole, TM210 release, shunt trip, 121 kA at 240 V.
