The rated insulation voltage is 800 V, and the interrupting capacity hits 75.6 kA at 240 V, dropping to 7.5 kA at 690 V — so it's built for high-fault scenarios on the low-voltage side of a transformer, not for 690 V motor circuits where the fault current is lower anyway. The breaker measures 130 mm tall, 76.2 mm wide, and 70 mm deep — a compact 3-pole footprint that fits standard SENTRON mounting bases in a distribution board. The 70 mm depth means it'll clear most shallow enclosures, but check the gland plate clearance if you're back-paneling with cable ducts. Max power loss is 8.5 W, so ventilation in a sealed cabinet is worth a thought if you're stacking several of these. The 25 A rating at 40-50 °C is the continuous current you can count on without derating — that's the number for sizing feeder cables and upstream protection. The 75.6 kA interrupting rating at 240 V is the headline number for high-fault locations like service entrances; at 415 V it's still 52.5 kA, which covers most industrial distribution.","metaTitle":"Siemens 3VA1025-3ED32-0HC0 SENTRON MCCB, 25 A, 3-Pole","metaDescription":"Siemens 3VA1025-3ED32-0HC0 SENTRON molded case circuit breaker, 25 A rated at 40°C, 3-pole, 75.6 kA at 240 V.
