Eaton gmc-2-r 2A 250V Time Delay Fuse Cylindrical

Product Description

The EATON gmc-2-r is a low breaking medium time delay fuse rated at 2 amps and 250 volts AC, built in a cylindrical glass body measuring 5 mm in diameter by 20 mm in length. It carries an interrupt rating of 100 A at 250 VAC and 10 kA at 125 VAC, making it suitable for protecting sensitive equipment where nuisance tripping from inrush current is a concern. The time delay characteristic allows up to 60 minutes at 135 percent of rated current and a maximum of 2 minutes at 200 percent, providing reliable overcurrent protection without unnecessary interruption during startup conditions. Ferrule terminals and holder-mount design support quick, secure installation in standard fuse holders.

The gmc-2-r is used in light industrial and commercial electrical equipment where compact 5x20 mm cylindrical fuses are specified. Typical applications include control panels, instrumentation, power supplies, and electronic equipment requiring low-amperage overcurrent protection. It is appropriate for circuits operating at up to 250 VAC and is installed by electricians and electronics technicians working on low-voltage control and instrumentation systems. The single-element, non-indicating, non-rejection design fits standard 5x20 mm fuse holders without polarity or orientation restrictions.

Installation Notes

Installation and replacement should be performed by a qualified electrician or instrumentation technician. Always de-energize and lock out the circuit before removing or inserting the fuse. Verify that the replacement fuse amperage and voltage ratings match the circuit requirements exactly before reinstalling. Consult applicable NEC guidelines and equipment documentation for proper fuse holder selection and circuit protection requirements.
