It carries 100 A continuously at 40 °C ambient — no derating needed until you cross 55 °C, where it steps down to 98 A, then 96 A at 60 °C, 94 A at 65 °C, and 91 A at 70 °C. That thermal curve means you can push it in a warm panel without losing headroom, as long as you stay under 55 °C for full current. Breaking capacity is 121 kA at 240 V AC, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V. Those numbers cover most industrial service-entrance and distribution applications where high fault current is a concern. The overcurrent release is a TM240 thermal-magnetic type — fixed thermal and magnetic trip, no electronic adjustment, which keeps it simple and reliable for standard feeder protection.
It measures 130 mm high, 101.6 mm wide, and 70 mm deep — a 4-pole MCCB that fits standard distribution panel footprints. The N-conductor protection is rated at 100% of the phase current, which matters for panels feeding nonlinear loads where the neutral carries harmonics. Power loss maxes out at 25 W — negligible for panel thermal budgeting, but worth noting if you're packing multiple breakers in a sealed enclosure.
