Q240 - 40Amp Circuit Breaker

Q240 - 40Amp Circuit Breaker

When you’re replacing a circuit breaker, getting the specifications right matters. The Q240 is a 40-amp, 2-pole Type QP plug-in circuit breaker rated at 10 kAIC at 120/240 VACC. Its two-pole configuration is intended for compatible applications requiring protection across both poles. At the same time, the plug-in design makes it a straightforward choice for equipment designed for Type QP breakers. The Q240 is also HACR-rated, so it can be used in qualifying heating, air-conditioning, and refrigeration applications where an HACR-rated breaker is called for. At just 2.88 inches high, 2.0 inches wide, and 2.56 inches deep, it packs the required 40-amp protection into a compact footprint. If you’re replacing an existing breaker, compare the part number and electrical ratings carefully rather than going by appearance alone. Matching the amperage, poles, voltage, AIC rating, and breaker type will help you determine whether the Q240 is the right fit for your equipment.

Key Features and Benefits

• 40-amp rating for compatible circuits requiring 40A overcurrent protection.
• Two-pole configuration for applications requiring simultaneous protection across both poles.
• Type QP design for use with compatible equipment designed to accept this breaker type.
• Plug-in construction provides a practical installation format for compatible panels and equipment.
• Rated 10k AIC at 120/240VAC.
• HACR-rated for qualifying heating, air-conditioning, and refrigeration applications.
• Compact dimensions make it easy to identify and compare against an existing breaker.
• Clearly defined electrical specifications take some of the guesswork out of finding the correct replacement.

Material Compliance and Certifications

• The available product specifications identify the Q240 as HACR-rated and list a 40°C temperature reference. Its interrupting rating is 10 kA at 120/240VAC.
• No additional material-compliance certifications or listings were provided with the supplied specifications, so none are assumed here. When a project has specific certification or code requirements, check the markings on the breaker and the appropriate product documentation before installation.

Where It Works Best

• The Q240 40A 2-pole breaker is a good match for compatible electrical panels and equipment specifically designed to accept Type QP plug-in circuit breakers. Its specifications also make it suitable for qualifying HVAC/R applications that require a 40-amp, two-pole, HACR-rated breaker with the stated voltage and interrupting rating.
