Q240H - 40Amp Circuit Breaker

Q240H - 40Amp Circuit Breaker

The Q240H is a 40-amp, 2-pole plug-in circuit breaker with a 22kA A.I.C. rating at 120/240VAC. It is a Type QPH breaker and is HACR-rated. If you're replacing an existing Q240H, this gives you the core specifications you'll want to compare before doing anything else: 40 amps, two poles, 120/240 VAC, and a 22 kA interrupting rating. The breaker measures 2.88 inches high, 2 inches wide, and 2.56 inches deep, so it doesn't take up much space. Its plug-in configuration is intended for compatible electrical equipment designed for this breaker type. The HACR rating is also worth noting when the breaker is being considered for compatible heating, air-conditioning, or refrigeration equipment. As with any circuit breaker replacement, don't rely on appearance or dimensions alone. Check the panel requirements and make sure the QPH type, amperage, voltage, poles, and A.I.C. rating are correct for the application.

Material Compliance and Certifications

• The supplied specifications identify the Q240H as HACR-rated and specify a 40°C rating. No other certification or material-compliance information was included in the available product data, so additional certifications shouldn't be assumed. For projects where a particular approval, listing, or material requirement is mandatory, check the markings on the breaker and the applicable technical documentation.

Where It Works Best

• This breaker makes sense when the electrical equipment calls for a 40-amp, 2-pole Type QPH plug-in breaker with a 22kA rating at 120/240VAC. It may be used in compatible residential, commercial, maintenance, or HACR-related applications, provided the electrical equipment is designed for it.
