At 55 °C it derates to 24 A, and at 70 °C it carries 23 A — the thermal curve is flat enough that a panel at 50 °C still gets full 25 A without oversizing. ## Breaking capacity by voltage Breaking capacity drops with system voltage as expected: 75.6 kA at 240 V AC, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at both 500 V and 690 V. That 75.6 kA figure at 240 V gives headroom for high-fault panels on 208/240 V services; at 415 V the 52.5 kA still covers most distribution boards without a current-limiting upstream breaker. ## Overcurrent release and auxiliaries The breaker ships with two HQ auxiliary switches built in, so you get status feedback without adding a separate accessory module. ## Line protection, not feeder or motor This variant is designated line protection — it's sized for cable and busbar protection in distribution panels, not for direct motor starting or feeder protection with adjustable long-time and short-time delays. The TM210 release is a simple thermal-magnetic curve; if your application needs electronic trip units or ground-fault monitoring, this isn't the variant. ## Panel fit Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — a standard 3-pole MCCB footprint for DIN-rail or panel-mount enclosures.","metaTitle":"Siemens 3VA1025-3ED32-0AC0 SENTRON MCCB, 25 A, 3-Pole, 75.6","metaDescription":"Siemens SENTRON 3VA1025-3ED32-0AC0 molded case circuit breaker, 25 A rated at 40 °C, 3-pole, breaking capacity 75.6 kA at 240 V AC.
