The headline breaking capacity is 220 kA at 240 V, stepping down to 154 kA at 415 V and 121 kA at 440 V — figures that govern selectivity coordination in high-fault panels. Maximum power loss is 8.5 W, a figure to factor into thermal budgeting inside a sealed enclosure. ## Panel fit — dimensions and mounting The breaker measures 76.2 mm wide, 130 mm tall, and 70 mm deep — a 3-pole footprint that fits standard SENTRON panel cutouts and busbar systems. No trip indicator or communication function is fitted; this is a straight thermal-magnetic unit for hardwired distribution.","metaTitle":"Siemens 3VA1125-6ED32-0AA0 SENTRON MCCB, 25 A, 3-Pole, 220 k","metaDescription":"Siemens SENTRON 3VA1125-6ED32-0AA0 molded case circuit breaker, 25 A rated at 40 °C, 3-pole, 220 kA breaking capacity at 240 V.
