Cooper Bussmann MEQ.5 Time-delay Midget Fuse 0.5A 500V

Product Description

The COOPER BUSSMANN MEQ.5 is a time-delay midget fuse rated at 0.5 amps and 500 volts, designed for supplemental protection of high-inrush power electronic circuits. Built with fiber tube construction, this non-indicating fuse delivers an interrupting rating of 10 kAIC. It is installed where overcurrent protection is needed downstream of a branch-circuit protective device, particularly in control panels, drives, and power electronics equipment. Licensed electricians and control panel builders typically specify this fuse in applications that demand both time-delay characteristics and a compact midget form factor.

This fuse is suited for supplemental protection in residential and commercial power electronic installations where high inrush current is present during startup. Typical applications include variable frequency drives, motor controls, and low-amperage power supply circuits that require time-delay response to handle transient inrush without nuisance opening. Its 500-volt rating makes it appropriate for a broad range of control and electronic circuit applications.

Key Features

• Time-delay design tolerates high-inrush power electronic circuits without nuisance opening
• Rated 0.5 amps at 500 volts for supplemental overcurrent protection
• 10 kAIC interrupting rating provides reliable fault current clearing
• Fiber tube construction offers durable, compact midget form factor
• Non-indicating design in a standard midget fuse configuration

Compatibility

Designed as an OEM-style supplemental protective device for control panels and power electronic circuits requiring a time-delay midget fuse in a standard midget form factor.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize and lock out the circuit before removing or installing the fuse. Verify that the fuse holder is rated for the 500-volt and 0.5-amp application before installation. Do not substitute a non-time-delay fuse where a time-delay type is specified, as nuisance opening may result.
