Motor control and protection is possible up to 15kW within a thermal trip adjustment range from 0.1 to 32A. The magnetic trip indicator avoids dangerous closing operations during short-circuit conditions, and the high breaking capacity – up to 100kA – eliminates the need for additional upstream fuses and breakers.

Each SM1 breaker is equipped with an automatic trip indicator, easily reset with a dedicated pushbutton. The breaker can be opened and closed via the front-facing toggle found on most standard circuit breakers.

SM1 series units also feature:

  • Class 10 overload trip characteristics
  • Phase loss and single-phase sensitivity
  • High trip accuracy
  • Long mechanical/electrical lifetime (100,000 cycles)
  • 35mm DIN rail mounting
  • IP20 enclosure

These motor protection circuit breakers are suitable with a wide variety of accessories including auxiliary blocks, undervoltage trip release, shunt release, terminal blocks for busbar supply and three-phase connection busbar add-ons.
