Those numbers tell you it's built for high-fault-current industrial feeders, not light commercial. The 75.6 kA at 240 V covers most North American 277/480 V panelboard applications on the line side; the 52.5 kA at 415 V handles European 400 V distribution. The 690 V rating at 11.9 kA means it can switch 690 V motor circuits in some regions, though you'd check the specific fault study. The breaker measures 76.2 mm wide, 130 mm tall, and 70 mm deep — a standard 3-pole MCCB footprint that drops into most SENTRON distribution panels and switchgear without surprises. Maximum power dissipation is 8.5 W, which matters for heat buildup in a packed enclosure.","metaTitle":"Siemens 3VA1125-3EE36-0AA0 SENTRON MCCB, 25A, 3-Pole, TM220","metaDescription":"Siemens SENTRON 3VA1125-3EE36-0AA0 molded case circuit breaker, 25A rated at 40°C, 3-pole, TM220 trip unit.
