Square D QO QO220GFICP Circuit Breaker, Mini, 20 A, 2 -Pole, 120/240 VAC, Plug Mounting

QO® (plug-on) and QOB (bolt-on) one, two and three pole thermal-magnetic circuit breakers provide overcurrent protection and switching on AC and DC systems. Plug-on QO circuit breakers are for use in QO load centers, NQ and NQOD panelboards, OEM mounting bases and Speed-D® switchboard distribution panels. Bolt-on QOB circuit breakers are for use in NQO and NQOD panelboards.

Has actuator type Magnetic Thermal, current rating 20 A, dimensions 1.5 in W x 2.91 in D x 4.12 in H.

• 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
