For a 480 V panel (common in North American industrial distribution) the relevant figure is the 440 V column at 52.5 kA — that is the closest published point, and it is the one an engineer would use for a 480 V system SCCR study. The 690 V rating of 11.9 kA is the floor; if your available fault current exceeds that at 600 V class, this breaker is not the right pick. ## Physical fit and auxiliary switch The breaker measures 76.2 mm wide, 130 mm tall, and 70 mm deep — a standard SENTRON 3VA frame size that drops into the same DIN-rail or panel-mount footprint as other 3-pole units in the series.","metaTitle":"Siemens 3VA1132-4EF32-0AF0 SENTRON MCCB, 32 A, 3-Pole, 121 k","metaDescription":"Siemens SENTRON 3VA1132-4EF32-0AF0 molded case circuit breaker, 32 A rated, 3-pole, 121 kA interrupting at 240 V.

The 3VA1132-4EF32-0AF0 carries a higher continuous rating (32 A vs the 3VA1110-5ED36-0AC0's lower rating) and a different TM release curve, so you need to verify that the upstream protection and downstream conductors are sized for 32 A before swapping."},{"question":"What compliance documentation does this brand provide for 3VA1132-4EF32-0AF0?","answer":"Siemens SENTRON MCCBs carry UL, CSA, and IEC certifications standard for the series.
