Breaking capacity runs from 75.6 kA at 240 V down to 10.5 kA at 690 V, so the spec sheet on the system's available fault current determines which voltage tap governs the installation. The 100 A rating holds flat through 50 °C ambient; above that it derates to 96 A at 55 °C and 90 A at 70 °C. Physical footprint is 76.2 mm wide by 130 mm tall by 70 mm deep — a 3-pole MCCB that fits standard DIN-rail or panel-mount cutouts for the SENTRON family. ## Auxiliary Contacts and Trip Indication The auxiliary release is an undervoltage release (UVR) — part number 3VA9608-0BB24 for the integrated trip unit.","metaTitle":"Siemens 3VA1110-3EF36-0CH0 SENTRON MCCB, 100 A, 3-Pole, Line","metaDescription":"Siemens SENTRON 3VA1110-3EF36-0CH0 molded case circuit breaker, 100 A rated, 3-pole, line protection.
