Miniature Circuit Breakers: 10kA 80A to 125AHti

Miniature Circuit Breaker (MCB), Residential

The miniature circuit breakers of the Series Hti are the biggest breakers within our range of MCB’s (210 g/pole). They are meant to be used for heavier applications, their nominal current goes upto 125A and they have a calibration temperature of 40°C (for the other MCB’s within our range this is 30°C, except for the Series GT).

This is also reflected in the terminal capacity for rigid cables, 70mm ² , while for other miniature circuit breakers this is maximum 16 (C-series) or 35mm ².

Following add-on devices are available for this product: auxiliary contacts, shunt trip (Tele L) and panel board switch (PBS).

No accessories are available for the Series Hti.

See below the main features for this range.

Modular Control Devices – Series PR – PriorityRelays

Modular Control Devices, Residential

Priority relays offer the possibility to limit the energy consumption in installations with a defined maximum power. This limitation is getting measuring the installation total current continuously and in the case consumption would be higher then fixed value, priority relay would disconnect the non-priority load.
