This item is a factory-original Potter & Brumfield (TE Connectivity) KUP series heavy-duty industrial general-purpose plug-in relay, part number KUP-14D55-80. Engineered for high-reliability switching inside demanding industrial machinery cabinets, legacy control enclosures, and commercial automation circuits, this clear-case logic relay features a specialized 80 VDC operating coil paired with a versatile 3PDT (Triple Pole Double Throw) power contact block.
The internal switching mechanisms are constructed with high-grade silver-cadmium oxide contacts capable of handling continuous electrical loads up to 10 Amps at 120V/250VAC. The complete assembly is enclosed inside a rugged, impact-resistant clear polycarbonate structural dust cover, allowing field technicians to easily run routine visual maintenance checks on the internal contact alignments and coil condition without opening the electrical loop.
Condition Note:
This unit is in Brand New Old Stock (NOS) / Uninstalled condition. The outer clear casing is highly transparent, scratch-free, and clean with all white technical load stamping crisply visible. The 11 lower quick-connect spade terminal prongs are completely straight, gleaming, and show zero mechanical clamp markings, solder residue, or field arcing paths, verifying this relay has never been placed into electrical service.
Practical Industrial Applications
- Machinery Control Loops: Handles auxiliary signal sequencing, safety lockouts, and multi-line control isolation inside automated assembly lines or process plant panels.
- Specialized DC Power Systems: Ideal logic control relay for battery bank monitoring arrays, telecommunications power distribution skids, or heavy material handling equipment running native 80V DC control architectures.
- HVAC-R Equipment Integration: Manages automated fan, heavy damper actuator, or secondary pump start signals inside older commercial building automation panels.
