That thermal curve lets you size the breaker for a 25 A load without oversizing for a warm enclosure, as long as ambient stays under 50 °C. Breaking capacity drops with system voltage: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at both 500 V and 690 V. At 240 V it handles high-fault commercial services; at 415 V it covers most European industrial distribution panels. ## Panel fit and environmental ratings Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep — a standard 3-pole MCCB footprint that fits SENTRON distribution blocks and panel-mounting feet. Maximum power loss is 8.5 W, which matters for thermal coordination inside a sealed enclosure.","metaTitle":"Siemens 3VA1025-3ED36-0AA0 SENTRON MCCB, 25 A, 3-Pole, 75.6","metaDescription":"Siemens SENTRON 3VA1025-3ED36-0AA0 molded case circuit breaker, 25 A, 3-pole, TM210 release.
