QBHW2020C - 20 Amp Circuit Breaker

QBHW2020C - 20 Amp Circuit Breaker

Need a QBHW2020C circuit breaker for a compatible panel or electrical system? This 20-amp, 2-pole breaker is part of the QBHW line and uses a bolt-on connection. It’s a thermal-magnetic circuit breaker, designed to protect against both overloads and short circuits. The QBHW2020C is rated 22kA at 120/240VAC and includes a switching neutral leg, an important detail for your applications that require the neutral to be switched along with the circuit. It’s also HACR rated, making it suitable for qualifying heating, air-conditioning, and refrigeration applications. Size-wise, the breaker measures approximately 3.41 inches high, 3 inches wide, and 2.92 inches deep. Replacing an existing breaker? Check more than just the 20A rating. The QBHW type, bolt-on mounting, two-pole design, voltage, A.I.C. rating, and switching-neutral configuration should all match your equipment's requirements.
