Mersen ATMR2-1/2 Midget Fuse 600V Cc 2.5 Amp

Product Description

The MERSEN ATMR2-1/2 is a time-delay midget fuse rated at 600 volts and 2.5 amps in a CC class form factor. Midget fuses in the CC class are used in control circuits, small motor loads, and branch circuit protection where a compact fuse holder is required. The time-delay characteristic allows the fuse to tolerate brief inrush currents without nuisance opening, making it well-suited for motor and transformer applications. Licensed electricians and HVAC technicians are the primary installers. The fuse measures 1.62 inches in length and weighs 0.21 pounds per unit.

The ATMR2-1/2 is designed for use in residential and light commercial electrical control panels, HVAC equipment control circuits, and industrial control enclosures where a CC class midget fuse holder is installed. It is commonly found protecting low-amperage branch circuits, transformer primaries, and motor control loads that require time-delay protection at 600 volts or below. These fuses are sold in packs of 10, making them a practical restocking item for service technicians and electrical contractors.

Key Features

• 600 volt rating suitable for standard North American branch circuit and control circuit applications
• 2.5 amp current rating with time-delay action to handle motor inrush without nuisance blowing
• CC class form factor ensures rejection of non-current-limiting fuses in compliant fuse holders
• Compact midget body fits standard CC midget fuse holders and blocks
• Sold in a 10-pack for efficient restocking on service calls and panel work

Compatibility

Designed as an OEM-style replacement for CC class midget fuse holders rated for 600 volts and 2.5 amps in residential and commercial electrical and HVAC control applications.

Installation Notes

Installation must be performed by a qualified electrician or licensed HVAC technician in accordance with the NEC and applicable local codes. Always de-energize the circuit and verify zero voltage with a meter before replacing fuses. Use the correct fuse puller for midget fuse blocks to avoid damaging the holder contacts. Never substitute a fuse with a higher amperage rating to restore a tripped circuit without first identifying the root cause of the overcurrent condition.
