Morris Products S-15 Type S Time Delay Plug Fuse 15A

Product Description

The MORRIS PRODUCTS S-15 is a Type S heavy-duty, dual-element time delay plug fuse rated at 15 amps and 125 volts AC with a 10 kiloampere interrupting rating. It uses a rejection base design that threads into Type SA adaptors, making it non-interchangeable with standard Edison-base fuses. The dual-element, spring-loaded construction provides superior protection against both short-circuit faults and sustained overloads. Electricians and electrical contractors install this fuse in residential loadcenters and panelboards where reliable overcurrent protection is required for motor circuits and frequently cycling loads.

This fuse is suited for residential loadcenter applications and is particularly effective for protecting critical motor circuits or motors that start and stop frequently. The extended time-delay characteristic allows motors to pull inrush current at startup without nuisance blowing, while still providing fast response to a true fault condition. Its industrial and commercial grade dual-element construction offers a higher level of time-delay protection than medium-duty Type S fuses, making it a strong choice in both residential and light commercial service environments.

Key Features

• Dual-element, time delay construction handles motor inrush current without nuisance blowing
• Rejection base type threads into Type SA adaptors and prevents substitution of lower-rated fuses
• 10 kiloampere interrupting rating provides robust short-circuit protection
• Spring-loaded design delivers superior short-circuit and overload response
• UL 248-11, CSA 1423-01, and CE listed for residential and commercial use
• Manufactured in the USA

Compatibility

Designed as an OEM-style replacement Type S plug fuse for use in residential loadcenters equipped with Type SA rejection-base adaptors. Compatible with standard 125-volt AC fuse panels that accept Type S rejection base fuses.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NFPA 70 (NEC) requirements. Always de-energize and lock out the panel before replacing fuses. Verify that the replacement fuse current rating matches the circuit requirement before installing. Type S fuses require a Type SA adaptor to be installed in the Edison-base socket prior to first use; the rejection base prevents insertion of a fuse with a higher ampere rating.
