Q315H - 15Amp Circuit Breaker

Q315H - 15Amp Circuit Breaker

Need a 15-amp, 3-pole circuit breaker with higher interrupting capacity? The Q315H Type QPH plug-in circuit breaker delivers the electrical ratings professionals look for in one compact package. Rated 15 amps with a 22kA interrupting rating at 240VAC, this three-pole breaker is designed for compatible electrical distribution equipment that calls for the QPH configuration. Its plug-in design makes it a practical choice for replacement and maintenance applications where the Q315H specifications match the existing equipment. It's also HACR-rated and specified for a 40°C ambient temperature, adding versatility for qualifying heating, air-conditioning, and refrigeration applications. At just 3.13 inches high, 3.0 inches wide, and 2.56 inches deep, the Q315H delivers substantial interrupting capacity in a compact form. Whether you're an electrician replacing an existing breaker, a maintenance professional working on electrical distribution equipment, or a facility manager tracking down an exact Q315H replacement, the key is getting the specifications right. Check the part number, amperage, number of poles, voltage, interrupting rating, and equipment compatibility before installation.

Key Features and Benefits

• A straightforward choice when your application specifically calls for a 15A three-pole breaker.
• Offers a 22,000-amp interrupting rating at 240 VAC, making it suitable for compatible systems that require this level of fault-current interruption.
• The QPH designation makes it easier to identify and match the breaker to compatible electrical equipment.
• Built for plug-in installation in equipment specifically designed to accept this breaker configuration.
• HACR-rated, suitable for qualifying heating, air-conditioning, and refrigeration applications when all equipment and system requirements are met.
• Rated for around a 40°C ambient temperature.
• Measuring approximately 3.13" H × 3.0" W × 2.56" D, the Q315H packs its electrical capabilities into a relatively small footprint.
• Clearly defined ratings help electricians and maintenance professionals quickly compare the Q315H with an existing breaker or equipment requirement.

Material Compliance and Certifications

• The Q315H circuit breaker is HACR-rated, an important consideration when evaluating the breaker for qualifying heating, air-conditioning, or refrigeration equipment. Published technical documentation for the QP/QPH breaker family identifies applicable standards including UL 489, CSA C22.2 No. 5-16, and NMX-J-266-ANCE, and identifies Type QPH breakers with a 22kA RMS symmetrical interrupting rating.
• Electrical ratings, approvals, and equipment compatibility matter, so don't rely on appearance alone when matching a breaker. Always confirm the markings on the breaker itself and review the requirements of the panel or other electrical equipment before installation.
  

Where It Works Best

• The Q315H 15 amp 3-pole QPH circuit breaker is a strong fit for electrical maintenance, replacement, and repair applications where compatible equipment specifically requires a 15A, 3-pole, Type QPH plug-in breaker with a 22kA rating at 240VAC.
  It can also be considered for qualifying heating, air-conditioning, and refrigeration applications that require an HACR-rated breaker with these electrical specifications. For maintenance teams and electricians, it's especially useful when the job calls for matching an existing Q315H rather than trying to make a different breaker configuration work.
