The SENTRON 3VM1125-4ED32-0AA0 is a 3-pole molded case circuit breaker (MCCB) rated for 25 A continuous current at 40 °C, with a TM210 thermal-magnetic release. Its interrupting capacity hits 121 kA at 240 V AC — enough to handle high-fault utility feeds without cascading upstream — and still clears 76 kA at 415 V, 53 kA at 440 V, and 11.9 kA at 500 V. That SCCR headroom makes it a solid choice for main or branch protection in panels where fault current is known to be high.
Above that it derates gently: 24 A at 55 °C and 60 °C, then 23 A at 65 °C and 70 °C.
At 76.2 mm wide, 130 mm tall, and 70 mm deep, this MCCB fits standard panel-mount cutouts for 3-pole SENTRON frames.
