QBHW3030HS - 30Amp Circuit Breaker

QBHW3030HS - 30Amp Circuit Breaker

The QBHW3030HS circuit breaker is a 30-amp, three-pole Quicklag Type QBHW thermal magnetic circuit breaker designed for dependable circuit protection in your compatible electrical distribution equipment. With a 22 kA interrupting rating at 240VAC, this breaker combines thermal and magnetic trip protection to respond to overload and short-circuit conditions. Its bolt-on mounting design provides a secure connection to compatible equipment. At the same time, the integrated 120VAC shunt-trip device adds remote-trip capability for your applications where external breaker operation is required. The QBHW3030HS is also HACR rated and specified for 40°C operation. Measuring approximately 3.41 inches high, 4.0 inches wide, and 2.92 inches deep, it delivers three-pole protection in a relatively compact footprint. For maintenance professionals, electrical contractors, facility teams, and equipment specialists searching specifically for QBHW3030HS, this breaker offers a precise combination of 30A capacity, 240VAC performance, bolt-on installation, and shunt-trip functionality. Published product data also identifies QBHW3030HS as a three-pole, 30A Quicklag breaker with a 22 kAIC interrupting rating.

Key Features and Benefits

• 30-amp, 3-pole configuration provides simultaneous circuit protection across three poles for compatible electrical systems.
• 22 kAIC at 240VAC is designed with a 22,000-amp interrupting capacity at 240VAC, providing the specified fault-current interruption capability.
• Thermal magnetic protection combines thermal overload response with magnetic short-circuit protection for effective everyday circuit protection.
• A 120VAC shunt trip device allows the breaker to be tripped by an external control signal, making it useful where remote shutdown is part of the system design.
• The bolt-on configuration creates a secure mechanical and electrical connection when installed in compatible equipment. Independent published specifications also identify the QBHW3030HS as bolt-on mounted.
• Part of the Quicklag QBHW family, helping technicians identify the correct breaker type when servicing or maintaining compatible equipment.
• HACR rated, suitable for applicable heating, air-conditioning, and refrigeration circuit applications when all system requirements are met.
• 40°C rating designed around a 40°C ambient calibration specification.

Material Compliance and Certifications

• Published product specifications identify QBHW3030HS as UL Listed and CSA Certified. Because circuit breakers are safety-critical electrical components, compatibility should be confirmed against the equipment manufacturer's specifications, electrical ratings, system requirements, and applicable electrical codes before installation. Installation and servicing should be performed by qualified electrical personnel.

Where It Works Best

• The QBHW3030HS 30A 3-pole circuit breaker is best suited for compatible electrical panels and distribution equipment requiring a QBHW bolt-on breaker with 30-amp protection, three poles, a 22 kAIC rating at 240VAC, and shunt-trip capability. Its combination of thermal-magnetic protection and remote shunt tripping makes it especially useful in commercial, industrial, HVAC, equipment control, and facility electrical applications where the system calls for these exact characteristics. Always match the complete QBHW3030HS part number and electrical specifications rather than selecting a breaker based only on amperage or physical dimensions.
