Breaking capacity is voltage-dependent: 121 kA at 240 VAC, 75.6 kA at 415 VAC, 52.5 kA at 440 VAC, and 11.9 kA at both 500 VAC and 690 VAC. These figures govern selectivity coordination with upstream devices and SCCR compliance for the panel assembly. ## Physical Integration and Auxiliary Configuration Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — a standard SENTRON 3VA frame size that mounts on a DIN rail or panel-mount adapter within the enclosure. Maximum power loss is 10.6 W. The trip indicator is present; undervoltage release and ground-fault monitoring are not fitted on this variant.","metaTitle":"Siemens 3VA1132-4EF36-0AH0 SENTRON MCCB, 32 A, 3-Pole, 121 k","metaDescription":"Siemens SENTRON 3VA1132-4EF36-0AH0 molded case circuit breaker, 32 A rated, 3-pole, 121 kA breaking capacity at 240 VAC.
