Square D™ Miniature Circuit Breaker, QO® Series, 3 Pole, 20 A, 120/240 VAC, 22 kA, Pressure Plate Connection, 14 to 8 AWG Al/Cu Wire, Bolt On Mount, For Use With: NQ Series Panelboards, 3 in H x 2.25 in W x 2.91 in D

QOB (bolt-on) 1, 2 and 3-pole thermal-magnetic circuit breakers provide overcurrent protection and switching on AC and DC systems. Bolt-on QOB circuit breakers are for use in NQO and NQOD panelboards. QOB circuit breakers have an overcenter, trip-free toggle mechanism with quick-make, quick-break action and positive handle indication. The tripping mechanisms in 2 and 3-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. Each pole has an individual thermal-magnetic trip element calibrated for 40 deg C ambient temperature.
