Features
- QO and QOB circuit breakers have an overcenter, trip-free toggle mechanism with quick-make, quickbreak action and positive handle indication
- The tripping mechanisms in two- and three-pole circuit breakers operate such that an overcurrent on any pole of the circuit breaker will cause all poles of the circuit breaker to open simultaneously
- QO and QOB circuit breakers have Visi-Trip trip indication, which provides a visual indication that the circuit breaker has tripped and interrupted the circuit
- The Visi-Trip indicator is only visible when the circuit breaker has tripped
- The circuit breaker can be reset by pushing the handle to OFF and then to ON
- When designing an electrical distribution system, overcurrent protective devices are generally selected based on performance requirements
- Factors influencing this selection include system voltage, continuous current, interrupting rating and frequency
- The continuous current rating of a circuit breaker is the maximum current in amperes which a device will carry continuously without exceeding the specified allowable temperature rise
- The interrupting rating of a circuit breaker is the highest current at rated voltage that the circuit breaker is intended to interrupt under standard test conditions
