The Bussmann BP/S-20 is a time-delay plug fuse designed to provide reliable overcurrent protection in Type S fuse holders. The dual-element design handles the temporary current surges common in circuits with motors, pumps, and other inductive loads—such as during motor start-up—without unnecessary nuisance trips. This makes it ideal for residential, commercial, and industrial electrical systems where brief overload conditions are normal and equipment protection is essential.
Time-delay (slow-blow) fuses are engineered to distinguish between harmless temporary overloads and genuine electrical faults. The fuse’s body size prevents interchangeability and dangerous over-fusing. The non-transferring design threads securely into SA adapters, providing protection across a range of electrical applications.
Features and Benefits
- Time-Delay (Slow-Blow) Action: Permits temporary surge currents from motor start-ups and inductive loads to pass without interruption, reducing nuisance trips while maintaining full fault protection.
- Dual-Element Design: Provides coordinated short-circuit and overload protection.
- Type S Compatibility: Fits standard Type S fuse holders; body size prevents interchangeability and dangerous mismatches.
- High Interrupt Rating: 10,000 amperes (10 kA) interrupt capacity for severe fault conditions.
- Non-Transferring, Spring-Loaded: Threads securely into SA adapters; design prevents accidental over-fusing.
- Industrial-Grade Reliability: UL Listed for use in residential, commercial, and industrial applications; backed by Bussmann’s decades of electrical safety expertise.
- Two-Pack Convenience: Two fuses per card for simplified inventory management and immediate replacement availability.
