Eaton SL-30PK4 30A Time-delay Plug Fuse 4-pack 125V

Product Description

The EATON SL-30PK4 is a medium-duty, time-delay plug fuse designed for residential electrical circuits that serve motors, relays, and solenoids. Rated at 30 amps and 125 volts AC with a 10,000 ampere interrupting capacity (AIC), this fuse provides reliable overcurrent protection in applications where inrush current is a normal operating condition. The rejection-base design uses porcelain threads that are tamper-resistant, physically preventing the installation of a higher-amperage fuse. An extra-large clear window gives technicians and inspectors an immediate visual indication of fuse condition without removing the fuse from the panel. Each pack contains four fuses.

The SL-30PK4 is suited for residential service panels and subpanels in kitchens, garages, and utility rooms where Type S rejection-base fuse holders are installed. It is appropriate for any branch circuit supplying electric motors, relay coils, or solenoid loads that draw elevated startup current. Electricians use this fuse as a direct replacement in existing Type S fuse panels or when retrofitting older screw-base panels with rejection bases to bring them into compliance. The four-pack format supports service technicians stocking common amperage ratings on the truck.

Key Features

• 30-amp time-delay rating handles motor inrush current without nuisance opening
• 125V AC rating with 10,000 A.I.C. for residential branch circuit protection
• Porcelain rejection-base threads prevent installation of a higher-amperage fuse
• Extra-large clear window allows fast visual blown-fuse inspection
• UL Listed for residential and light commercial motor circuit applications
• Four-fuse pack for convenient truck stock and service calls

Compatibility

Designed for use in Type S rejection-base fuse holders and panels rated for SL-series plug fuses. Compatible with residential circuits supplying electric motors, relays, and solenoids where a 30-amp, 125-volt time-delay fuse is required.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. Always shut off the main breaker or disconnect power to the panel before servicing fuses. Verify the circuit voltage and amperage rating match the fuse specifications before installation. Do not bypass or substitute a fuse with a higher amperage rating than the circuit is designed to carry.
