Q340 - 40Amp Circuit Breaker

Q340 - 40Amp Circuit Breaker

Looking for a Q340 40-amp 3-pole circuit breaker for a compatible electrical system? The Q340 is a Type QP plug-in circuit breaker designed to provide dependable overcurrent protection while keeping installation straightforward in equipment specifically designed for this breaker type. Rated at 40 amps and 240VAC, this three-pole breaker has a 10kA interrupting capacity at 240VAC and is HACR rated, making it a practical option for qualifying heating, air-conditioning, and refrigeration applications. Its compact plug-in design measures approximately 2.88 inches high, 3.0 inches wide, and 2.56 inches deep. Whether you're replacing an existing breaker or matching a breaker to compatible distribution equipment, the Q340 gives electricians, maintenance teams, and facility professionals an easy-to-identify combination of 40A capacity, three-pole protection, Type QP construction, and 240VAC performance. Just remember that breaker selection isn't about physical fit alone; the electrical ratings and compatibility with approved equipment also need to match.

Material Compliance and Certifications

• The Q340 Type QP circuit breaker is HACR-rated, supporting its use in qualifying heating, air-conditioning, and refrigeration applications when the electrical system and equipment requirements call for this Type of breaker. The available specifications also identify a 40°C temperature rating/note.
  Because circuit breakers are safety-critical electrical components, certification markings, panel compatibility, and applicable installation requirements should always be confirmed using the breaker labeling and the documentation for the equipment in which it will be installed. This is especially important when replacing an existing breaker; similar dimensions or appearance do not necessarily mean two breakers are interchangeable.

Where It Works Best

• The Q340 40A 3-pole Type QP breaker is a strong fit for compatible electrical distribution equipment requiring a 40-amp, three-pole, 240VAC plug-in circuit breaker with a 10kA interrupting rating. Its three-pole configuration makes it particularly relevant for compatible three-phase circuits, while the HACR rating supports qualifying HVAC and refrigeration applications.
