Cooper Crouse-Hinds GUP315 Explosionproof Junction Box
Overview
The Cooper Crouse-Hinds GUP315 is a compact explosionproof junction box designed for threaded rigid conduit systems in hazardous industrial areas, functioning as a junction or pull box wherever mounting space is limited – a common constraint around gasoline dispensers, skid-mounted equipment, and congested process piperacks. Built from Feraloy iron alloy with a copper-free aluminum cover, the GUP315 is the largest hub-size member of the GUP compact junction box family, fitted with 1 in trade size hubs on all four faces to accommodate larger conductor bundles than the smaller GUP215 and GUP314 variants.
As the official authorized partner and exclusive regional representative for Cooper Crouse-Hinds, Seven Star LLC proudly supplies the GUP315 explosionproof junction box to oil and gas, fuel distribution, and industrial process facilities across Oman and the wider GCC. Every unit is genuine Crouse-Hinds product with full manufacturer traceability, and our technical team supports specification, hub configuration, and compliant installation of hazardous-area junction boxes throughout the Sultanate of Oman.
Sealing and Containment Principle
The Cooper Crouse-Hinds GUP315’s cast Feraloy iron alloy body and copper-free aluminum cover form a flame-path enclosure that contains any internal arc, spark, or explosion event, preventing it from igniting the surrounding hazardous atmosphere – the fundamental requirement for explosionproof equipment under UL 886 and UL 1203. A neoprene O-ring gasket seated in the cover provides an additional UL Type 4 watertight rating for the enclosure, keeping moisture and dust out of the wiring compartment even in exposed outdoor or washdown locations.
Internally, the Cooper Crouse-Hinds GUP315 provides 29 cubic inches of wiring capacity, sufficient for splicing and pulling conductors between the multiple 1 in hubs positioned on the top, bottom, side, and back faces of the enclosure. An internal green ground screw is factory provided to terminate the equipment grounding conductor, while raised ears molded into the cover assist technicians in tightening and removing the cover during installation or maintenance without specialist tools.
Engineering Design of the Cooper Crouse-Hinds GUP315
The Cooper Crouse-Hinds GUP315 body measures 4.88 in by 4.88 in by 2.97 in deep and weighs approximately 6.65 lb, with a hub configuration of (2) 1 in top hubs, (2) 1 in bottom hubs, (1) 1 in side hub, and (4) 1 in back hubs – nine total conduit entry points on a single compact body. The unit ships complete with (3) 1 in pipe plugs to close unused hub openings, and both the Feraloy body and aluminum cover are finished to resist corrosion in humid, coastal, and offshore GCC installation environments.
The Cooper Crouse-Hinds GUP315’s compact footprint relative to its hub count makes it a preferred choice where multiple conduit runs must terminate or pass through a single point without the larger physical envelope of a standard explosionproof enclosure. This design lineage, shared across the GUP215, GUP214B, GUP314C, and GUP315D catalog variants, allows specifying engineers to select the hub size and count that best matches a given application while retaining a common mounting footprint across the family.
Key Features
The Cooper Crouse-Hinds GUP315 delivers reliable explosion containment in a space-efficient junction box footprint:
- Nine 1 in trade size hubs – (2) top, (2) bottom, (1) side, (4) back – for flexible conduit routing.
- Feraloy iron alloy body with copper-free aluminum cover for corrosion resistance and mechanical strength.
- Neoprene O-ring cover gasket provides UL Type 4 watertight rating for outdoor and washdown service.
- 29 cubic inch internal wiring capacity for splicing and pulling multiple conductor bundles.
- Rated for Class I Div 1 & 2 Groups C, D; Class II Div 1 Groups E, F, G; Class II Div 2 Groups F, G; Class III.
- UL 886 and UL 1203 listed, CSA C22.2 No. 30 certified for explosionproof and dust-ignitionproof service.
- Internal green ground screw factory provided for equipment grounding conductor termination.
- Compact 4.88 in x 4.88 in x 2.97 in footprint suited to space-constrained mounting locations.
Industrial Applications
The Cooper Crouse-Hinds GUP315 explosionproof junction box is specified wherever hazardous-area conduit runs must be spliced or pulled through in a compact footprint: gasoline dispensing and fuel distribution terminals, refinery process units, offshore and onshore oil and gas production facilities, and skid-mounted equipment packages where larger junction box enclosures cannot be accommodated. Its multiple hub configuration makes it especially useful at conduit transition points where several smaller runs converge before continuing on to a motor control center or field panel.
As the officially authorized partner for Cooper Crouse-Hinds, Seven Star LLC distributes the GUP315 to EPC contractors, panel builders, and fuel infrastructure maintenance teams across Muscat, Sohar, and the Salalah free zone, supporting both new-build hazardous-area electrical installations and shutdown/turnaround replacement programs. Our regional stock holding and direct manufacturer relationship help shorten lead times compared with sourcing individually from overseas distributors, with full datasheet and certification support available for Oman and GCC regulatory submissions.
