MCCB for 100 A feeder and branch protection
Its TM210 thermal-magnetic release provides fixed overload and short-circuit protection without the need for external relays — a straightforward fit for 100 A feeder circuits, busway taps, or large motor branch circuits where adjustable electronic trip is not required. 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 690 V — high enough for most low-voltage distribution systems with high fault current potential.
The 100 A rating holds flat from 40 °C to 50 °C, then derates to 96 A at 55 °C, 94 A at 60 °C, 92 A at 65 °C, and 90 A at 70 °C.
