CHARACTERISTICS
•
Circuit breakers are rated 240 Vac single-phase and 415 Vac three-phase, 50/60 Hz, 3–100 A.
•
Circuit breakers are available in 1-, 2- or 3-pole construction.
•
Thermal trip elements are factory calibrated to 40°C (IEC 947-2) and30°C (IEC 898) ambient temperature.
•
RCBO devices available with 10 mA, 30 mA and 100 mA residualcurrent protection.
•
Trip-free handle ensures tripping even when the circuit breaker is held orlocked in the ON position.
•
Circuit breakers are in compliance with international standards set bythe International Electrotechnical Commission (IEC).
•
The CE marking is located on each circuit breaker in accordance withthe low-voltage directive of the European Union.
•
The entire QO circuit breaker family provides the advantage of a plug-onconnection. (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 thepotential for hazardous arcs on the line side of the circuit breaker.
