The 187 kA breaking capacity at 240 V AC handles high-fault service-entrance or sub-distribution boards; at 415 V it still interrupts 121 kA, and at 690 V it holds 17 kA. ## Thermal derating — the real ampacity in a warm panel Above that it steps down: 122 A at 55 °C, 120 A at 60 °C, 117 A at 65 °C, 114 A at 70 °C. The TM210 trip unit is fixed thermal plus magnetic; no adjustment dial, so the curve is what it is. The case measures 130 mm tall, 101.6 mm wide, 70 mm deep — a 4-inch wide footprint that matches the 3VA1110/1112 family.","metaTitle":"Siemens 3VA1112-5FD46-0AA0 SENTRON MCCB, 125 A, 4-Pole, TM21","metaDescription":"Siemens 3VA1112-5FD46-0AA0 SENTRON molded case circuit breaker, 125 A rated at 40 °C, 4-pole, TM210 trip unit, breaking capacity 187 kA at 240 V.

The difference is the trip unit — this one carries a TM210 thermal-magnetic release; the 5EE32 variant uses an electronic trip. If the panel wiring and load current match the 125 A rating, the swap is a straight mechanical drop-in. Verify the trip curve coordination with downstream devices before committing."},{"question":"What is the breaking capacity of this MCCB at different voltages?","answer":"At 240 V it interrupts 187 kA; at 415 V, 121 kA; at 440 V, 75.6 kA; at 500 V and 690 V, 17 kA.
