The insulation voltage is rated 800 V, so it handles 480Y/277 V and 600 V panel feeds without issue. ## Breaking capacity across voltages This MCCB delivers 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at 500 V and 690 V. That means it can clear high-fault currents on the secondary side of a 150 kVA transformer, but at 480 V the available fault current needs to stay under 32 kA — typical for most industrial panelboards. The 7.5 kA at 690 V covers 690 V drives or mining gear. Rated 25 A continuous from 40 °C up to 50 °C. At 55 °C it derates to 24 A, and at 70 °C it holds 23 A. Ambient operating range is -25 °C to 70 °C; storage from -40 °C to 80 °C. Maximum power loss is 8.5 W. ## Auxiliary and release configuration The shunt trip allows remote tripping from a PLC or E-stop circuit — common for safety isolation in conveyor or HVAC systems. The 3VA1025-3ED32-0JH0 measures 130 mm high, 76.2 mm wide, and 70 mm deep. The 76.2 mm width (3 inches) is a standard 3-pole MCCB footprint — fits existing busbar and enclosure cutouts without modification. The depth of 70 mm (2.76 in) leaves room for rear-access wiring in a 200 mm deep enclosure.","metaTitle":"Siemens 3VA1025-3ED32-0JH0 SENTRON MCCB, 25 A, 3-Pole, 75.6","metaDescription":"Siemens 3VA1025-3ED32-0JH0 SENTRON molded case circuit breaker, 25 A rated, 3-pole, 75.6 kA breaking at 240 V.
