TE Connectivity W28-XQ1A-5 Circuit Breaker

The TE Connectivity W28-XQ1A-5 is a professional-grade 5A thermal circuit breaker designed for high-reliability HVACR control panels and commercial appliance protection. This single-pole fuseholder type circuit breaker serves as a robust alternative to standard slow-blow glass fuses, providing a resettable solution that eliminates the need for spare fuse inventory in the field. Built with a push-to-reset button and a black with white rate marking bezel, it offers clear visual trip indication—the black button extends outward when an overload occurs, allowing technicians to identify faults at a glance during diagnostic rounds.

Engineered for panel mount applications, the W28-XQ1A-5 features 0.250" (6.35mm) quick-connect terminals for rapid chassis wiring. It is rated for up to 250VAC and 32VDC, providing versatile protection across different power stages. The snap-in mounting design ensures a secure fit in standard cutouts, significantly reducing labor time during installation or field replacement of legacy thermal breakers. This unit is UL 1077 recognized as a supplementary protector, making it a staple for equipment protection in heating and cooling systems.

• Resettable Thermal Protection: Replaces disposable glass fuses with a reliable push-to-reset mechanism, minimizing system downtime.
• Visual Diagnostic Tool: The black button actuator extends upon tripping, providing immediate status feedback for maintenance personnel.
• Versatile Compatibility: Rated for both 250VAC and 32VDC, making it suitable for a wide range of HVACR control circuits.
• Efficient Installation: Integrated quick-connect terminals and a snap-in panel mount body allow for fast, tool-free mounting in the field.

• Can this breaker replace a 5-amp slow-blow fuse? Yes, the W28-XQ1A-5 is specifically designed to replace traditional fuse holders with a resettable thermal element while maintaining the same protection profile.
• What is the maximum voltage for the DC rating? This 5Amp circuit breaker is rated for up to 32VDC, suitable for low-voltage control systems and automotive applications.
• Does the button stay recessed during normal operation? Yes, the push-to-reset button stays flush against the black bezel and only pops out when the internal thermal element trips due to an overload.
