The Bussmann BP/S-8 is a heavy-duty time-delay plug fuse designed to protect motor circuits and equipment that cycles on and off frequently. Time-delay (slow-blow) fuses are essential for applications where temporary current surges occur during normal operation, such as motor startup. Unlike standard fast-acting fuses that would trip unnecessarily, this Type S fuse allows brief overload currents to pass while providing reliable protection against sustained overcurrent and short circuits.
The dual-element, spring-loaded design of this fuse responds quickly to dangerous short circuits while tolerating the inrush currents that are normal when motors start. The Type S body design prevents dangerous interchangeability—its distinctive size ensures it can only be inserted into compatible holders, eliminating the risk of over-fusing a circuit. This fuse threads into standard SA adapters and is UL Listed for safety and reliability.
Features and Benefits
- Time-delay design: Handles temporary current surges from motor startup and cycling loads without nuisance trips, keeping your equipment running reliably.
- Dual-element construction: Spring-loaded mechanism provides both short-circuit protection and overload protection in a single component.
- Type S body: Distinctive size prevents dangerous interchangeability and over-fusing, protecting critical circuits from unsafe protection levels.
- Heavy-duty industrial grade: Built for commercial and industrial applications with motors and inductive loads.
- Non-transferring: Designed so it cannot be replaced with an incorrect fuse type, enhancing system safety.
- SA adapter compatible: Threads into standard SA adapters for easy installation in existing fuse panels and distribution boxes.
