2 International Miniature Circuit Breakers 0739DB9901R11/03 CHARACTERISTICS Circuit breakers are rated 240 Vac single-phase and 415 Vac threephase, 50/60 Hz, A. Circuit breakers are available in 1-, 2- or 3-pole construction. Thermal trip elements are factory calibrated to 40 C (IEC 947-2) and 30 C (IEC 898) ambient temperature. RCBO devices available with 10 ma, 30 ma and 100 ma residual current protection. Trip-free handle ensures tripping even when the circuit breaker is held or locked in the ON position. Circuit breakers are in compliance with international standards set by the International Electrotechnical Commission (IEC). The CE marking is located on each circuit breaker in accordance with the low-voltage directive of the European Union. The entire QO circuit breaker family provides the advantage of a plug-on connection. (Bolt-on connections also available.) Advantages of the Plug-on System A 50% reduction on installation time compared to a lug/lug (DIN) alternative. No link bars to fit and tighten. Contact jaws automatically align the circuit breakers in the equipment. High short circuits result in an increase in jaw pressure reducing the potential for hazardous arcs on the line side of the circuit breaker. Figure 1: Plug-on System
