The 75.6 kA at 240 V and 52.5 kA at 415 V are the SCCR values that determine whether this breaker coordinates with downstream equipment. At 440 V it still delivers 32 kA, and at 500 V and 690 V it holds 11.9 kA — that's the same figure at both voltages, which is unusual and suggests the arc-quenching design is optimized for that range. At 55 °C it derates to 24 A, and at 70 °C it holds 23 A — that's a shallow curve, meaning the TM210 release is thermally stable. For a cold-chain panel running at 25 °C ambient, you get the full rating with margin. For a BOM freeze or last-time-buy planning, the active status means no immediate replacement risk — but if you need a documented cross-reference for a second-source gate, the closest functional peer in the same SENTRON 3VA family is the 3VA1110-5ED36-0AA0, which carries a lower interrupting capacity and a different release type. The 3VA1125-3GD46-0AA0 drops into the same panel cutout as that peer without rewiring, but verify the SCCR coordination study before swapping.","metaTitle":"Siemens 3VA1125-3GD46-0AA0 SENTRON MCCB, 25 A, 4-Pole, 75.6","metaDescription":"Siemens SENTRON 3VA1125-3GD46-0AA0 molded case circuit breaker, 25 A, 4-pole, TM210 release, interrupting capacity 75.6 kA at 240 V.

For 480 V (common in North American distribution), the value falls between those two points; the 32 kA at 440 V gives you a conservative ceiling."},{"question":"Will 3VA1125-3GD46-0AA0 drop into a panel specified around 3VA1110-5ED36-0AA0?","answer":"Yes — both share the same 4-pole SENTRON 3VA frame dimensions (101.6 mm wide, 130 mm tall, 70 mm deep), so the cutout and bus connections are identical.
