MCCB for 80 A feeder and branch protection
Its TM210 thermal-magnetic overcurrent release handles the overload and short-circuit trip curves without external power — a straightforward fit for standard line protection where no communication, ground-fault monitoring, or phase-failure detection is needed. The interrupting ratings scale with system voltage: 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 690 V. At 415 V, that 32 kA SCCR covers most industrial panelboard and motor-control-center fault duties without cascading upstream breakers — a practical headroom for a 80 A frame. Current-carrying capacity holds flat at 80 A through 50 °C ambient, then derates to 76.8 A at 55 °C, 75.2 A at 60 °C, 73.6 A at 65 °C, and 72 A at 70 °C.
Its footprint is 130 mm high, 76.2 mm wide, and 70 mm deep — a standard 3-pole MCCB envelope that fits most existing panel layouts without re-drilling. No auxiliary contacts, undervoltage release, or ground-fault module are integrated on this variant.
The 3-pole design covers three-phase loads; the line-protection version means it trips on overload and short-circuit only — no additional ground-fault or phase-loss logic. For DC network applications, the manufacturer directs to the 3VA molded case circuit breaker device manual for switching power values.
