Cooper Bussmann SL-30PK4 Type Sl Plug Fuse 30A 4 Pack

Product Description

The COOPER BUSSMANN SL-30PK4 is a 30-amp Type SL plug fuse sold in a four-pack for residential electrical service applications. Type SL fuses feature a time-delay design that allows brief motor startup inrush current while still providing overcurrent protection against sustained faults. The non-tamper construction means the fuse can only accept the correct amperage rating for the circuit, preventing unsafe overrating. This pack is a standard stocking item for electricians and HVAC technicians who service older residential load centers, dryer circuits, and appliance branch circuits that use Edison-base fuse panels.

Type SL plug fuses are used in residential fuse panels where screw-in Edison-base fuses are required by the installed equipment. The time-delay characteristic makes them suitable for circuits serving motors and compressors, including window air conditioning units, sump pumps, and similar loads that draw high inrush current on startup. The non-tamper feature limits the fuse socket to 30-amp maximum, which helps maintain circuit integrity in older service equipment. These are appropriate for use in both service-entrance and branch-circuit fuse panels.

Key Features

• 30-amp rating with Type SL time-delay characteristic for motor and compressor circuits
• Non-tamper design prevents substitution of a higher-amperage fuse in the same socket
• Edison-base plug fuse format for use in standard residential fuse panels
• Four-pack quantity supports stocking needs for service calls and panel maintenance
• Boxed packaging keeps fuses protected during transport and storage

Compatibility

Designed as an OEM-style replacement for residential fuse panels that accept Type SL Edison-base plug fuses rated at 30 amps.

Installation Notes

Type SL plug fuses are installed and serviced by licensed electricians following applicable NEC requirements for fused service equipment. Always shut off the main disconnect or service entrance before replacing fuses in the panel. Verify that the circuit voltage and amperage requirements match the fuse rating before installation. Do not bypass or substitute a fuse of a different type or amperage rating for the one being replaced.
