QBHW2020 - 20 Amp Circuit Breaker

QBHW2020 - 20 Amp Circuit Breaker

When you're replacing a circuit breaker, getting the details right matters. The QBHW2020 is a 20-amp, 2-pole Quicklag circuit breaker with a bolt-on connection and thermal-magnetic protection. It is rated for 120/240VAC and has a 22kA interrupting rating, giving you the specifications needed for compatible electrical distribution applications. This breaker is also HACR-rated and specified for 40°C. Measuring 3.41 inches high, 2 inches wide, and 2.92 inches deep, the QBHW2020 has a compact footprint that makes it straightforward to compare against an existing breaker. Whether you're handling routine maintenance, repairing electrical equipment, or replacing a breaker that's already in service, the important thing is getting the right match. Check the QBHW type, 20A rating, two-pole configuration, voltage, interrupting capacity, dimensions, and bolt-on connection against your equipment requirements before installation.
