Product Description

Bussmann SL-20PK4 20 Amp Time Delay Loaded Link Rejection Base Plug Fuse, 125V UL Listed, 4-Pack

About This Item

Introducing the Bussmann SL-20PK4 20 Amp Time Delay Loaded Link Rejection Base Plug Fuse, UL Listed and available in a convenient 4-pack. Designed to meet major industrial standards and agency requirements such as UL, NEMA, and CSA, this fuse is perfect for residential motor circuits in kitchens, workshops, garages, utility rooms, or any circuit with motors, relays, or solenoids. The rejection base threads of this fuse prevent a larger amp fuse from being used, ensuring the safety of your electrical system.

For example, the different-sized threads mean that a 30 amp fuse cannot be installed in a 20 amp receptacle. This medium-duty fuse is threaded for easy installation into fuse receptacles and features a rejection base with porcelain threads. It is important to note that this fuse is not interchangeable with the Edison Base (brass threads) type.

With time-delay functionality, the Bussmann SL-20PK4 is ideal for use on motor circuits. It provides maximum protection with a voltage rating of 125Vac. By using plug fuses like the SL-20PK4, you can effectively protect furnace blower motors, pumps, power tools, garage door openers, and more.

These fuses are often used in conjunction with branch circuit protection. When a dangerous overload occurs, these fuses open the circuit, preventing damage to electrical motors. This not only helps reduce downtime but also lowers maintenance costs.

The Bussmann SL-20PK4 comes in a convenient three-pack blister pack, providing a compact and affordable solution for motor and branch circuit protection. Whether you need to protect your residential or industrial electrical system, the Bussmann SL-20PK4 20 Amp Time Delay Loaded Link Rejection Base Plug Fuse is the perfect choice for reliable and efficient performance. UL Listed for peace of mind, this fuse guarantees the highest standards of safety and quality.
