Product details

The Siemens 3VA1140-5EE42-0AA0 is a 4-pole SENTRON molded case circuit breaker (MCCB) designed for line protection, fitted with a TM220 thermal-magnetic overcurrent release. Rated 40 A continuously at 40 °C ambient, it holds that rating through 50 °C before a slight derating curve begins — 39 A at 55 °C, 37 A at 70 °C, per the datasheet. The interrupting capacity reaches 187 kA at 240 V, stepping down to 121 kA at 415 V and 75.6 kA at 440 V, with a floor of 17 kA at 500 V and 690 V. That high-fault rating makes it suitable for installation close to large transformers or in high-available-fault-current industrial distribution.

Physical fit and panel integration

Dimensions are 130 mm height, 101.6 mm width, and 70 mm depth — a 4-pole MCCB that fits standard Siemens SENTRON mounting footprints. The front face carries IP40 protection, suitable for enclosed panel mounting where no water ingress is expected. No undervoltage release or shunt trip is fitted on this variant; the TM220 release is the only internal trip element.
