The TM-D trip provides L (thermal overload) and I (magnetic short-circuit) protection in one block. Set the thermal pickup at the 100 A rating; the magnetic pickup is fixed within the trip unit. This is a distribution-grade breaker (Category A utilisation) — no intentional short-time delay for selective coordination, so it trips instantaneously on fault currents above the magnetic threshold.
Mounts on a backplate (not DIN rail) — the 105 x 161 x 86 mm (W x H x D) footprint fits standard MCCB cutouts. Horizontal or vertical mounting is allowed; flat on the backplate. Power dissipation is 7.7 W per pole.
Isolation suitability is confirmed per that standard, so it can be used as a disconnecting means. The IP40 front face and IK07 mechanical impact rating are per IEC 60529 and IEC 62262 respectively.
