30 A rating paired with a 42 kAIC interrupt capacity means the QHCX2030 can safely interrupt high fault currents common in industrial drives and motor circuits. This translates to reduced damage to feeders, transformers, and connected equipment, minimizing costly downtime when faults occur. The 120/240 V operating range supports common control and power circuits, making it well suited for mixed-voltage panels in manufacturing environments. Thermal-magnetic trip with T268 characteristics delivers fast, predictable response to overloads while preventing nuisance trips during startup surges. This improves machine availability and simplifies fault diagnosis in lines with multiple devices sharing feeders. In practice, it enables better selectivity with adjacent protection and reduces false trips during automated equipment start-up. Cable-in/cable-out termination simplifies field wiring by eliminating extra terminal blocks and jumpers. This reduces assembly time and wiring errors, speeding up panel wiring for new equipment or retrofit projects. The configuration also supports straightforward integration with pre-terminated cables and clean, serviceable terminations in tight control enclosures. Compact footprint—3.9 in long, 3 in wide, 2 in high—with a weight of 0.8 lb. The small form factor increases panel density, leaving space for cable routing and future expansion. For retrofit projects or retrofits in legacy equipment, its dimension compatibility helps avoid enclosure modifications and supports easier service access. Additionally, the non-interchangeable design reduces the risk of mis-wiring during maintenance. UL Listed and CSA Certified with a 1-year warranty offers regulatory confidence and vendor support. This combination reduces risk during audits and procurement cycles, helping procurement teams justify the choice of a single, approved protection device across multiple machines. The QHCX2030 is built for industrial reliability and ongoing availability in automation systems. Long service life and spare parts availability support maintenance planning.

FAQs
The QHCX2030 is a two-pole miniature circuit breaker designed for industrial control panels with cable-in/cable-out terminations. It is suitable for standard panel enclosures used in manufacturing and automation environments. Mounting follows the manufacturer’s panel specifications, and the unit’s compact footprint supports dense layouts without sacrificing protection. Always verify panel manufacturer guidelines for correct installation clearances.
The QHCX2030 features a 42 kAIC interrupt rating and a thermal-magnetic trip type (T268). This combination provides fast response to overloads and efficient clearing of high fault currents while maintaining selectivity with other protective devices in the same panel. It’s suitable for circuits carrying up to 30 A at 120/240 V.
Yes, the QHCX2030 is UL Listed and CSA Certified. These certifications confirm compliance with widely recognized safety and performance standards, supporting regulatory approvals and audits in North American facilities. For procurement and maintenance teams, UL/CSA certification reduces risk when standardizing protection devices across multiple machines.
Cable-in/cable-out termination simplifies field wiring by reducing terminal blocks and jumpers, speeding up initial wiring and decreasing wiring errors. This eases retrofits and panel upgrades, especially in dense enclosures. It also supports cleaner cable routing and easier servicing, since conductors are terminated at the breaker itself.
The QHCX2030 carries a 1-year warranty and is designed for industrial reliability. Its rugged construction, regulatory certifications, and compact form factor contribute to lower maintenance costs and reduced downtime over the life of an automation installation. Long-term vendor support and availability of replacement parts further enhance total cost of ownership.
