Mersen ATQR5-6/10 600V Cc Time-delay Fuse

Product Description

The MERSEN ATQR5-6/10 is a 600-volt, Class CC time-delay fuse designed for overcurrent protection in commercial and industrial electrical systems. The time-delay characteristic allows the fuse to tolerate brief inrush currents common during motor and transformer startup without nuisance opening, while still responding quickly to sustained fault conditions. Class CC fuses are physically dimensioned to fit only Class CC fuse holders, preventing substitution with lower-rated fuseholders. Licensed electricians and industrial maintenance technicians are the primary installers of this fuse type.

Class CC time-delay fuses are commonly specified in motor branch circuits, control panels, and power distribution equipment where inrush tolerance and a compact form factor are required. The ATQR series is suited for both residential and light commercial control circuits as well as industrial feeder and branch circuit protection applications where the 600-volt rating provides appropriate margin for standard North American distribution voltages.

Key Features

• 600-volt rating provides compatibility with standard North American distribution circuits
• Class CC form factor prevents installation in incompatible, lower-rated fuseholders
• Time-delay design tolerates motor and transformer inrush without nuisance tripping
• Compact Class CC dimensions suit space-constrained control panels and disconnect enclosures

Compatibility

Designed for use in Class CC fuseholders and fuse blocks rated for 600 volts. The Class CC form factor is standardized, restricting installation to holders specifically designed for this fuse class.

Installation Notes

Installation must be performed by a qualified electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize and lock out the circuit before removing or installing any fuse. Verify the fuseholder is rated for Class CC fuses and that the circuit voltage and amperage do not exceed fuse ratings. Never bypass or replace a fuse with a higher-rated device to resolve a tripping issue without first identifying and correcting the fault condition.
