Line protection MCCB for a cold-chain panel
Its interrupting capacity reaches 75.6 kA at 240 V AC and still holds 11.9 kA at 690 V AC, so it handles high-fault scenarios common in industrial refrigeration switchgear without cascading upstream.
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.
