Breaking capacity is the other headline number: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 690 V. That is a high-interrupting rating for a 100 A frame, suited for transformer-secondaries or high-fault industrial panels. That makes it a straightforward line-protection breaker for cable and busbar protection, not a motor-protection or selective device. The 76.2 mm width is a 3-pole frame — three module-widths at roughly 25.4 mm per pole — so it occupies three adjacent 45 mm DIN spaces in a typical distribution board.","metaTitle":"Siemens 3VA1110-4EF36-0KA0 SENTRON MCCB, 100 A, 3-Pole, TM24","metaDescription":"Siemens 3VA1110-4EF36-0KA0 SENTRON molded case circuit breaker, 100 A rated continuous current, 3-pole, TM240 thermal-magnetic release, 121 kA at 240 V.

The 3VA1110-4EF36-0KA0 uses a fixed thermal-magnetic trip; the electronic version offers adjustable settings. Footprint and bus connections are the same, so it can drop into the same panel without rewiring, but the trip curve and coordination study will differ."},{"question":"Will 3VA1110-4EF36-0KA0 fit in a panel designed for 3VA1110-5EE32-0JA0?","answer":"Yes — both share the same 3VA frame dimensions: 130 mm height, 76.2 mm width, 70 mm depth. The mounting hole pattern and bus-bar connection points are identical. No rewiring needed for the mechanical fit."},{"question":"What compliance documentation does Siemens provide for this MCCB?","answer":"As a current-production SENTRON device, Siemens provides CE declaration of conformity, RoHS and REACH compliance declarations, and IEC/EN 60947-2 test certificates.
