Its TM210 thermal-magnetic release handles overloads and short circuits without external trip units — a fixed-trip design that simplifies spec and reduces failure points in the field. Interrupting capacity runs 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 690 V — the 415 V figure is the one that governs most European industrial panels. At 690 V the 7.5 kA limit means this breaker is not the right choice for high-fault 690 V buswork; step up to a higher-rated frame if your SCCR exceeds that.
Full 80 A rating holds through 50 °C ambient; above that it derates to 76.8 A at 55 °C, 75.2 A at 60 °C, 73.6 A at 65 °C, and 72 A at 70 °C. Above 50 °C, plan the load accordingly. Dimensions are 70 mm deep, 101.6 mm wide, 130 mm tall — a standard 4-pole MCCB footprint that drops into SENTRON distribution blocks and panelboards without adapter plates. IP40 on the front is typical for enclosed mounting; no IP rating on the terminals means it lives inside a cabinet, not exposed.
Auxiliaries and lifecycle
The TM210 release is non-interchangeable, so what you order is what you get; no field-swap trip units. Lifecycle status is current production — no phase-out notice on this order code.
