Guardamotor, 1.6-2.5. SM1R0250
SM1R are modern circuit breakers with thermal and magnetic trip releases and high breaking capacity.
Thermal Adjustmen Range: 2.5-4A. Rotary knob type. Short circuit breaking capacity Icu at 400V: 100kA.
Rated insulation voltage Ui: 690V. Frequency: 50/60Hz. Adjustment ranges: 16. Phase failure sensitive. Mounting on 35mm DIN rail (IEC/EN 60715). Protection: IP20.
A magnetic trip indicator integrated on the SM1R breakers avoids dangerous closing operations during short-circuit conditions, previously disconnected by the breaker. SM1R motor protection circuit breakers can be padlocked in OFF position without using accessories.
Certifications obtained: cULus, EAC. SM1R breakers are Type E-certified (Self-Protected Combination Motor Controllers) according to UL 60947-4-1.
Compliant with standards: IEC/EN 60947-1, IEC/EN 60947-2, IEC/EN 60947-4-1, UL 60947-4-1, CSA C22.2 n° 60947-1, CSA C22.2 n° 60947-4-1. Plastic materials compliant with standards: IEC/EN 60335 and EN 45545.
Their high breaking capacity consents to exclude protection fuses on the majority of the installations.
