General characteristics
The SM1 is a modern series of circuit breakers with thermal and magnetic trip releases and high breaking capacity. Motor control and protection, up to 15kW at 400V, are possible by choosing the suitable adjustment range, 0.1 to 32A.
A magnetic trip indicator integrated on the SM1 breakers avoids dangerous closing operations during short-circuit conditions, previously disconnected by the breaker. The SM1 types are suitable for isolation according to IEC/EN 60947 standards. Their high breaking capacity consents to exclude protection fuses on the majority of the installations.

NOTE: When more than one breaker are mounted, side by side, without leaving space between each to consent free air circulation on the breaker sides, and have simultaneous operation, the thermal trip adjuster must be positioned at a value 15% higher than the rated
motor current.
O The SM1C version consents to the mounting in enclosures and modular consumer switchboards with minimum depth of at least 45mm between the DIN rail and the opening. See page D-2 for exact breaker dimensions. No front-mount auxiliary contacts 11 SMX11... can be used.
