Mersen ATQR3/16 Special Purpose Fuse 600V

Product Description

The MERSEN ATQR3/16 is a special purpose fuse rated for 600 volts. Fuses in this class are passive overcurrent protection devices that interrupt a circuit when current exceeds a safe threshold, preventing damage to downstream equipment and wiring. The ATQR3/16 is a time-delay style fuse suited for circuits where inrush current is present at startup, such as motor loads and transformer-fed control circuits. Licensed electricians and industrial maintenance technicians are the primary installers of this type of device.

This fuse is intended for use in commercial and industrial electrical systems where 600-volt rated overcurrent protection is required. Typical applications include motor branch circuits, control panels, and process equipment where reliable, code-compliant fuse protection is necessary. The ATQR designation indicates a time-delay, current-limiting fuse class appropriate for demanding electrical environments.

Key Features

• 600-volt voltage rating for commercial and industrial applications
• Time-delay characteristics suited for motor and transformer inrush loads
• Current-limiting design helps reduce arc flash energy
• Compact form factor typical of the ATQR fuse series

Compatibility

Designed as an OEM-style replacement for special purpose fuses in 600-volt rated fuse blocks and disconnect switches that accept the ATQR form factor.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize and lock out the circuit at the disconnect or panel before removing or installing any fuse. Use an approved fuse puller rated for the voltage class when servicing live-adjacent panels. Verify replacement fuse ampere and voltage ratings match the circuit requirements before installation.
