MCCB for panel builders — 100 A, 4-pole, high interrupt capacity
It carries a rated continuous current of 100 A across the full ambient temperature range from 40 °C up to 70 °C, so no derating is needed for warm enclosures — a practical advantage when the breaker sits near other heat sources on the DIN rail. The interrupting ratings are substantial: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3.7 kA at 690 V. Ground-fault monitoring is built in via summation current formation on L + N conductors, so it can detect leakage without an external GFCI module.
The breaker measures 140 mm wide, 181 mm high, and 86 mm deep. The 140 mm width is standard for a 4-pole MCCB in this frame size; it will fit the same DIN-rail footprint as other SENTRON 3VA2 breakers of the same pole count.
The 100 A continuous rating is flat from 40 °C to 70 °C ambient. Insulation voltage is rated at 800 V. Breaking capacity drops sharply at 690 V to 3.7 kA — this is not the breaker for a 690 V motor control center unless the available fault current at that voltage is verified to be under that value. At 415 V and below, however, the 187 kA and 242 kA figures give you selectivity headroom for series-rated systems.
