The TM-D trip gives you fixed thermal overload (L) and fixed magnetic short-circuit (I) protection; no adjustment dials, so what you order is what protects the circuit. The 4-pole configuration (3 phases + neutral) suits a 3-phase 4-wire system where the neutral is switched. Mounts on a backplate, not a DIN rail — this is a bolted-down MCCB for a panel or enclosure, with front connections top and bottom. The 140 mm width, 161 mm height, and 86 mm depth fit the standard NSX100F cutout. The IK07 impact rating means it withstands a 2 J hammer blow — robust enough for an industrial panel door.
Compliance and approvals
Suitability for isolation is confirmed per that standard — you can use it as a disconnecting means. No earth-leakage protection built in — the TM-D trip handles overload and short-circuit only. If you need ground-fault protection, you add a Vigi module externally. The breaker is rated for horizontal and vertical mounting, flat on the backplate, which gives flexibility in panel layout.
