Cooper Bussmann LENRK15 Class RK1 Fuse 15A 250V

Product Description

The COOPER BUSSMANN LENRK15 is a Class RK1 non-indicating fuse rated at 15 amps and 250 volts, designed for high in-rush current motor protection applications. With an interrupting rating of 200 kAIC, it provides robust overcurrent protection in demanding electrical systems. This fuse is installed by licensed electricians in branch circuit and motor circuit applications where reliable, time-delay protection against high starting currents is required. Its Class RK1 designation ensures it meets the stricter dimensional and performance standards associated with that fuse class.

The LENRK15 is suited for residential and light commercial electrical panels and motor branch circuits where motors with high starting in-rush currents are present. Typical applications include protecting single-phase motors, control circuits, and related equipment in HVAC, industrial, and general electrical distribution systems. This fuse is a standard 250-volt Class RK1 type commonly used in fused disconnect switches and panelboards.

Key Features

• 15-amp current rating for motor branch circuit protection
• 250-volt maximum voltage rating
• Class RK1 designation for superior current-limiting performance
• 200 kAIC interrupting rating for high fault-current environments
• Non-indicating design with no visual blown indicator
• High in-rush current tolerance suited to motor starting loads

Compatibility

Designed as an OEM-style replacement Class RK1 fuse for use in standard fused disconnects, panelboards, and motor circuit protective devices rated for 250 volts and accepting Class RK1 form-factor fuses.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). Always de-energize and lock out the circuit before removing or installing fuses. Verify that the replacement fuse matches the ampere rating, voltage rating, and fuse class required by the overcurrent protection device and circuit design. Do not substitute a higher-ampere or lower-class fuse as a replacement.
