Thermal Circuit Breaker 1120 Description Double pole combined circuit breaker and ON/OFF switch with rocker actuation. Specially suited to single-phase applications. Snap-in front panel mounting. Thermal positively trip free mechanism ensures reliable overcurrent protection and safe physical isolation of the load circuit. Attractively styled, with rocker illumination optional. The status of the switching contacts is shown by the position of the rocker actuator. For high volume requirements customer-specific designs can be offered for the front bezel and the rocker. It meets the requirements of the CBE standard EN 60934 (IEC 60934): S type, TO. Meets the requirements regarding fire resistance of EN 60335-1 : 2007-02 Safety of household and similar electrical appliances. 1120-.. without water splash protection Minimum ordering quantities apply! Typical applications with water splash protection 2 Technical data Electrical motors, household appliances, office equiment, garden and hobby tools, power supplies, charging rectifiers, cable extension reels, multiple socket outlets.
