At 415 V it still interrupts 75.6 kA, and at 690 V it holds 11.9 kA. This is not a motor-protective breaker — the TM240 release is a fixed thermal-magnetic curve for feeder and distribution protection. The 3VA1110-4EF36-0AD0 measures 76.2 mm wide by 130 mm tall by 70 mm deep — a standard 3-pole MCCB footprint that fits SENTRON distribution boards and most DIN-rail-mount enclosures with the appropriate adapter. The 70 mm depth keeps it clear of gland plates and backpanel wiring troughs in 200 mm deep enclosures. Three auxiliary switches (HQ design) can be stacked on the side without increasing the width beyond the 76.2 mm frame.","metaTitle":"Siemens 3VA1110-4EF36-0AD0 SENTRON MCCB, 100 A, 3-Pole, 121","metaDescription":"Siemens SENTRON 3VA1110-4EF36-0AD0 molded case circuit breaker, 100 A at 40 °C, 3-pole, 121 kA interrupting at 240 V.
