TE Connectivity W28-XQ1A-1 Circuit Breaker
The TE Connectivity W28-XQ1A-1 is a professional-grade 1Amp thermal circuit breaker designed to provide reliable overcurrent protection in space-constrained panels. Engineered as a superior replacement for glass fuses, this Potter & Brumfield W28 series breaker features a hardware-free snap-in panel mount design that significantly reduces installation labor. Built for single-pole applications, it supports a maximum operating voltage of 250VAC and 32VDC, making it a versatile choice for HVACR controls, medical equipment, and industrial power management. The push-to-reset mechanism provides a clear visual trip indicator—the black button extends upon interruption—allowing technicians to quickly diagnose circuit faults. This unit is calibrated to continuously carry 100% of its rating and is designed to trip at 175% load within one hour at 25°C. With 0.250-inch quick-connect terminals and a dielectric strength exceeding 1500V RMS, the W28-XQ1A-1 circuit breaker ensures secure electrical contact and robust safety performance in demanding field environments.
Key Benefits for Technicians:- Labor-Saving Installation: The snap-in front panel mounting fits standard 0.635" x 0.625" holes without the need for additional mounting hardware.
- Enhanced Visual Feedback: The black button with a white rate-marking bezel provides immediate visual confirmation of a tripped state.
- Broad Compatibility: Rated for both 250VAC and 32VDC, allowing for integration across various AC and DC control circuits.
- Robust Interrupt Capacity: Capable of handling a 1,000A interrupt current at its rated voltage to prevent catastrophic equipment failure.
- Standardized Connectivity: Features industry-standard .250" (6.35mm) quick-connect spade terminals for fast, secure wiring.
Can I use the W28-XQ1A-1 to replace a 1A slow-blow glass fuse?
Yes, the W28-XQ1A-1 is specifically designed as a fuseholder-type circuit breaker to replace 3AG-style slow-blow fuses, offering the benefit of resettability after a trip event.
What is the trip response time for this breaker?
Under a 200% overload condition, this thermal breaker is engineered to trip within a window of 4.5 to 28 seconds, providing necessary protection while preventing nuisance tripping during minor surges.
Will this fit in my existing control panel?
This model is designed for panel mounting in materials 0.032" to 0.062" thick, utilizing a standard "D" shaped or square cutout for secured snap-in fitment.
