Hubbell Incorporated HBL5278C flanged straight blade inlet 15 A 125 V

HBL5278C Flanged Inlet 15 A 125 V

This flanged straight blade inlet provides a 15 A, 125 V power connection point for equipment or panels. Impact resistant thermoplastic construction protects the assembly in demanding environments. Backwired terminations and #8-32 multiple drive terminal screws simplify field wiring. Mounting screws are included for immediate installation.

Replacing Worn or Inadequate Panel Inlets

The HBL5278C replaces damaged or lower rated inlets where a secure 15 A connection is required. The jump is worth it when existing hardware shows heat damage, loose terminals, or cracked housings. Backwired terminations reduce installation time compared to side wired alternatives. The impact resistant body withstands mechanical abuse better than standard phenolic parts.

Sustained Load Behaviour and Thermal Stability

Under continuous 15 A loading the thermoplastic housing and terminal screws maintain mechanical integrity without softening. Multiple drive screws resist loosening from thermal cycling and vibration. Backwired terminations distribute current evenly across the conductor, minimising hot spots during extended operation. The assembly remains reliable in sustained duty cycles typical of fixed equipment.
