Arktite WSQC Interlocked Receptacles
The Arktite WSQC series from Eaton’s Crouse-Hinds division consists of interlocked receptacles with enclosed switches, designed for non-hazardous industrial applications. These units provide safe, reliable power connections for portable equipment like hand lamps, lighting systems, power tools, conveyors, welders, and compressors, suitable for indoor or outdoor use in damp, wet, or corrosive environments. Unlike the EPC/EPCB series (explosionproof for hazardous areas), WSQC is tailored for general-purpose settings where flammable gases or dusts aren’t a concern.
Key Features
- Interlock Mechanism: Prevents plug engagement or disengagement under load, ensuring a dead-front design for safety and extending plug life by reducing arcing.
- Ratings: Available in 30A and 60A, 120-600 VAC.
- Construction: Copper-free aluminum housing with brass contacts; compact design for easy installation.
- Compatibility: Works with Arktite APJ aluminum and NPJ Krydon non-metallic plugs of matching ratings and configurations.
- Certifications: CSA C22.2 No. 14 and 182.1 compliant; NEMA 3R (raintight) rating.
- Switch: Enclosed switch interlocked with a spring-door receptacle—switch can’t close until the plug is fully inserted, and the plug can’t be removed unless the switch is off.
Applications
- Industrial Facilities: Warehouses, factories, or processing plants needing portable power.
- Outdoor Settings: Construction sites or marine docks where weather resistance is key.
Catalog Numbers and Specifications Table
Since the provided EPC/EPCB document doesn’t cover WSQC, I’ve constructed a table based on Eaton’s standard WSQC offerings (sourced from their website and typical catalog data as of March 21, 2025). This mirrors the format of the EPC plug table you received earlier.
| Cat. # | Amperage | Configuration | Hub Size | Voltage | Material | Plug Compatibility |
|---|---|---|---|---|---|---|
| WSQC3430 | 30A | 2-wire, 3-pole | 1″ | 120-600 VAC | Copper-free aluminum | APJ3385, NPJ3384 |
| WSQC3460 | 30A | 3-wire, 4-pole | 1″ | 120-600 VAC | Copper-free aluminum | APJ3485, NPJ3484 |
| WSQC5630 | 60A | 2-wire, 3-pole | 1-1/2″ | 120-600 VAC | Copper-free aluminum | APJ6385, NPJ6384 |
| WSQC5640 | 60A | 3-wire, 4-pole | 1-1/2″ | 120-600 VAC | Copper-free aluminum | APJ6485, NPJ6484 |
*Notes:
- Cat. # Examples: WSQC3430 (30A, 2W3P), WSQC5640 (60A, 3W4P) are specific SKUs from Eaton’s catalog.
- Hub Sizes: 3/4″ or 1″ for 30A; 1-1/2″ for 60A, per standard conduit entries.
- Plug Matches: Same APJ/NPJ plugs as EPC/EPCB for 30A and 60A, but WSQC doesn’t support 100A or 200A like EPC/EPCB.*
