FAQs
WSQC5640 is built for a 1-1/2\" trade size and 60A rating, featuring a three-wire, four-pole configuration with an enclosed switch. For correct mounting, follow the IF 1371 instruction sheet, ensure alignment with Arktite WSQC interlocks, and use appropriate enclosure supports to maintain the NEMA 3R rating during installation.
The interlocked receptacle design physically prevents unplugging while the switch is engaged, reducing the risk of arc flash and unintended shutdowns. This ensures controlled power disconnection during maintenance, minimizes operator exposure, and supports safe sequencing of motor and drive operations in harsh or noisy environments.
Yes, WSQC5640 is UL-listed for interlock receptacles, with NEC/CEC compliance and a NEMA 3R enclosure rating. It is suitable for ordinary/non-hazardous locations, and the unit aligns with CB/UL certification expectations for motor controllers and manual operations in typical industrial facilities.
WSQC5640 is designed to integrate with the Arktite WSQC interlock family. Mounting uses standard WSQC enclosures and supports 1-1/2" trade size fittings. For best results, reference the Arktite WSQC interlock installation guidelines (IF 1371) and ensure proper enclosure sealing to maintain the 3R rating in intended environments.
The WSQC5640 reduces maintenance downtime through a secure interlock mechanism and robust 60A current handling, lowering field-disconnection risks and arc-flash exposure. Its copper-free aluminum housing and brass contacts contribute to durable service life, fewer part replacements, and lower lifecycle costs in daily industrial operation.
