This puts it in the distribution-duty category per EN/IEC 60947-2, suitable for isolation (marked yes per the standard). For a 50/60 Hz AC network, the TM-D trip handles both overload (thermal) and short-circuit (magnetic) protection in one compact 108 mm wide, 137 mm high, 80 mm deep footprint.
The 9 mm pitch takes 12 modules of DIN space. Connection terminals accept compression lugs or busbars, with front-facing upside and downside connections — panel builders can wire both line and load from the front without flipping the breaker. Neutral sits on the left. The grey (RAL 7016) housing with toggle control and a green flag for auxiliary contact presence gives visual status at a glance. IK07 impact rating handles accidental tool strikes during commissioning.
Electrical durability is rated 20,000 cycles at 440 V at In/2, and 10,000 cycles at 440 V at In. Mechanical durability matches at 20,000 cycles. Operating altitude reaches 2000 m without derating, 5000 m with derating. Relative humidity range is 0 to 95 %. No earth-leakage protection built in — that is handled separately.
