Eaton SL-15PK4 Time-delay Plug Fuse 15A 125V 4-pack

Product Description

The EATON SL-15PK4 is a medium-duty, time-delay plug fuse rated at 15 amps and 125 volts AC, sold in a 4-pack. It uses a rejection-base design with porcelain threads that physically prevent the installation of a higher-amperage fuse, protecting circuits from overcurrent misapplication. The extra-large clear window allows a technician to visually confirm a blown fuse without removing it. With a 10,000 A interrupting capacity (AIC), this fuse is built to handle the inrush current typical of motor loads while providing reliable overcurrent protection on branch circuits.

This fuse is rated for residential and light commercial branch circuits where motors, relays, or solenoids are present. Common installation locations include kitchen appliance circuits, garage circuits, and utility room panels. The time-delay characteristic accommodates the high inrush current drawn when an electric motor starts, preventing nuisance blowing while still protecting the circuit during a sustained fault. It is a direct plug-in replacement for standard Edison-base fuse holders that accept the SL rejection-base style.

Key Features

• Time-delay design handles motor inrush current without nuisance blowing
• Rejection-base porcelain threads prevent installation of a higher-amperage fuse
• Extra-large clear window allows visual inspection without fuse removal
• 10,000 AIC interrupting capacity for residential branch circuit protection
• UL listed for safety compliance
• Sold as a 4-pack for convenient stocking and replacement

Compatibility

Designed for use in residential and light commercial fuse holders that accept the SL rejection-base plug fuse format, including kitchen, garage, and utility room branch circuits containing electric motors, relays, or solenoids.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). Always shut off power at the main panel and verify the circuit is de-energized before replacing a fuse. Confirm the fuse amperage matches the circuit rating before installation. Do not bypass or substitute a fuse with a higher amperage rating; the rejection-base design enforces this at the hardware level.
