Mersen ATM1-1/2 Midget Fuse 600V 1.5A Time-delay 10-pack

Product Description

The MERSEN ATM1-1/2 is a 600-volt time-delay midget fuse rated at 1.5 amps, designed for protecting low-amperage branch circuits and control circuits in commercial and industrial electrical systems. The compact midget form factor fits standard 13/32-inch x 1.5-inch midget fuse holders. Time-delay construction allows brief inrush currents to pass without nuisance tripping while still providing fast response to sustained overloads and short-circuit faults. Electricians and controls technicians install this fuse in motor control panels, HVAC equipment control circuits, and low-amperage branch circuit applications.

This fuse is suited for residential and commercial applications where control circuit protection is required. Typical installations include transformer secondary protection, instrumentation circuits, and control panel branch circuits where compact fuse dimensions and precise ampere ratings are critical. The 600-volt rating provides a wide margin of safety across most single-phase and three-phase control circuit voltages encountered in field service.

Key Features

• 600-volt AC rating supports a broad range of control circuit applications
• 1.5-amp time-delay rating allows motor and transformer inrush without nuisance opening
• Midget form factor fits standard 13/32-inch x 1.5-inch fuse holders
• Sold in a 10-pack for convenient stocking and serviceability
• Compact dimensions of 1.62 inches x 0.88 inches x 2.12 inches for space-constrained panels

Compatibility

Designed as an OEM-style replacement midget fuse for use in standard 13/32-inch x 1.5-inch midget fuse holders rated for 600 volts AC in control panel and branch circuit applications.

Installation Notes

Installation must be performed by a qualified electrician in accordance with NEC requirements for overcurrent protection devices. Always de-energize and lock out the circuit before removing or installing a fuse. Verify that the replacement fuse ampere rating and voltage rating match the circuit requirements before installation. Do not substitute a higher-ampere fuse to correct a nuisance-opening condition without first identifying and correcting the root cause of the overcurrent.
