Rated 25 A continuous at 40 °C ambient, it holds that rating through 50 °C, then derates to 24 A at 55 °C and 23 A at 70 °C. That thermal curve matters for panels in hot environments — a 25 A breaker in a 65 °C switchroom is effectively a 23 A device. At 70 mm deep, 76.2 mm wide, and 130 mm tall, the 3-pole breaker occupies a standard MCCB footprint for DIN-rail or panel-mount installation.","metaTitle":"Siemens 3VM1125-4EE36-0AA2 SENTRON MCCB, 3-Pole, 25 A, 121 k","metaDescription":"Siemens 3VM1125-4EE36-0AA2 SENTRON molded case circuit breaker, 3-pole, 25 A rated, 121 kA interrupting at 240 VAC.

Availability and current pricing are confirmed at quote time — submit an inquiry for a firm commercial offer."},{"question":"What is the interrupting capacity of 3VM1125-4EE36-0AA2 at different voltages?","answer":"The interrupting capacity is 121 kA at 240 VAC, 76 kA at 415 VAC, 53 kA at 440 VAC, and 12 kA at 500 VAC. These values govern where the breaker can be applied based on available fault current at the installation point."},{"question":"What does the TM220 release designation mean?","answer":"TM220 indicates a thermal-magnetic release — the thermal element handles overload protection with a fixed time curve, and the magnetic element provides instantaneous short-circuit response. It is a standard fixed-trip design, not adjustable."},{"question":"Will 3VM1125-4EE36-0AA2 drop into a panel specified around 5SQ2370-2YA05?","answer":"Both are 3-pole molded case circuit breakers in a similar physical class, but the 5SQ2370 series is a different manufacturer's offering.
