What this MCCB delivers
The SENTRON 3VA1150-5EE36-0AA0 is a 3-pole molded case circuit breaker rated for 50 A continuous current, with a TM220 thermal-magnetic release designed for line protection. Its interrupting capacity reaches 187 kA at 240 V, 121 kA at 415 V, and 75.6 kA at 440 V, tapering to 17 kA at 500 V and 690 V — covering most industrial distribution panels and motor branch circuits up to those fault levels. The 50 A rating holds steady from 40 °C through 50 °C ambient, then derates gradually to 45 A at 70 °C — useful when the breaker sits in a warm enclosure near other heat sources.
Panel fit and thermal budget
The 76.2 mm width (3 in) and 70 mm depth (2.76 in) let it land in a standard MCCB slot on a DIN rail or panel-mount base. Height is 130 mm (5.12 in). Maximum power loss is 14.6 W — plan ventilation if grouping several breakers in a sealed cabinet.
