Cooper Crouse-Hinds N2PS1111 N2S Explosionproof Pushbutton Station
Overview
The Cooper Crouse-Hinds N2PS1111 is a non-metallic explosionproof pushbutton station from the N2S series, built around a corrosion-resistant Krydon fiberglass-reinforced polyester enclosure engineered for demanding Class I, Division 2 hazardous locations. The N2PS1111 provides a single momentary contact circuit with 1NO-1NC configuration rated to 600 VAC, giving plant electricians and control system integrators a compact, lightweight remote pushbutton for starting and stopping motors, actuating solenoids, or triggering interlocks in classified process areas without the added weight and cost of a metallic enclosure.
With engineering support in Muscat, Seven Star LLC proudly supplies the N2PS1111 pushbutton station to oil and gas, petrochemical, and water treatment operators across Oman and the wider GCC. Every unit is genuine Crouse-Hinds product with full manufacturer traceability, and our technical team supports specification, sizing, and compliant installation for hazardous-area control station networks throughout the Sultanate of Oman.
Operating Principle
The Cooper Crouse-Hinds N2PS1111 uses a factory-sealed momentary contact mechanism housed entirely within the Krydon polyester body, eliminating the need for external conduit seals at the device itself – a key advantage over metallic pushbutton stations in wet, corrosive, or space-constrained installations. Depressing the button closes the normally-open (NO) contact and opens the normally-closed (NC) contact simultaneously, sending a momentary signal to the associated magnetic starter, contactor, or PLC input; releasing the button returns both contacts to their normal state.
For the Cooper Crouse-Hinds N2PS1111, because the enclosure and internal contact block are factory sealed as a single assembly, the N2PS1111 requires no field-poured sealing compound and no moving mechanical linkage beyond the button itself, resulting in a low-maintenance device with excellent long-term reliability in Class I, Division 2 atmospheres. The glass-reinforced polyester body also resists the corrosion, UV degradation, and thermal cycling that would otherwise shorten the service life of comparable metallic control stations installed outdoors or in coastal GCC environments.
Engineering Design of the Cooper Crouse-Hinds N2PS1111
The Cooper Crouse-Hinds N2PS1111 enclosure measures a compact 3.6 in deep by 1.5 in wide by 2 in high and weighs approximately 0.4 lb, making it one of the lightest hazardous-area pushbutton stations in the Crouse-Hinds catalog. The Krydon fiberglass-reinforced polyester material provides excellent resistance to corrosion, heat, and sunlight exposure, and the unit carries a NEMA 3/4X/7BCD(Div.2)/12 rating suited to washdown areas, outdoor installations, and process units where dust and moisture ingress must be controlled.
On the Cooper Crouse-Hinds N2PS1111, internally, the single-circuit 1NO-1NC contact block is factory wired and sealed to the enclosure body, with the device requiring only field connection to power and control wiring through its threaded conduit hub. The N2PS1111 is UL 1203 listed and CSA C22.2 certified for Class I, Division 2, Groups B, C and D hazardous locations, and is typically mounted individually or ganged with matching N2S selector switches and pilot lights to build a complete non-metallic control station assembly.
Key Features
The Cooper Crouse-Hinds N2PS1111 delivers a lightweight, corrosion-resistant pushbutton solution for Division 2 hazardous areas:
- Factory-sealed Krydon fiberglass-reinforced polyester enclosure eliminates the need for external conduit seals.
- 1NO-1NC momentary contact configuration rated 600 VAC for direct interface with starters, contactors, and PLC inputs.
- NEMA 3/4X/7BCD(Div.2)/12 rating suited to washdown, outdoor, and dusty process environments.
- Rated for Class I, Division 2, Groups B, C and D hazardous locations per UL 1203 and CSA C22.2.
- Compact, lightweight body (approximately 0.4 lb) reduces mounting stress on panel and pedestal installations.
- Excellent corrosion, UV, and thermal resistance for long service life in coastal and offshore GCC environments.
- Compatible with the wider N2S non-metallic control station family for ganged multi-function assemblies.
- No field-poured sealing compound required, simplifying commissioning and reducing installation labor.

Industrial Applications
The Cooper Crouse-Hinds N2PS1111 pushbutton station is specified throughout Division 2 hazardous process areas: oil and gas production facilities, refinery utility areas, water and wastewater treatment plants, grain handling and processing operations, and any classified location requiring a lightweight remote start/stop or interlock pushbutton. Its non-metallic construction makes it particularly well suited to corrosive or humid environments where metallic control stations would require more frequent maintenance.
Backed by genuine manufacturer documentation, Seven Star LLC distributes the N2PS1111 to EPC contractors, panel builders, and plant maintenance teams across Muscat, Sohar, and the Salalah free zone, supporting both new-build hazardous-area control networks and shutdown/turnaround replacement programs. We supply on request with lead time and availability confirmed at quotation, with full datasheet and UL certification support available for Oman and GCC regulatory submissions.

Where Crouse-Hinds explosionproof equipment is used
Most of these parts belong to rigid conduit systems in classified areas: refinery units, gas compression and metering stations, tank farms, loading racks, paint and solvent handling, and offshore modules across the GCC. The listed series are built around the North American Class and Division system, but the rating differs by item: N2S stations are marked for Class I, Division 2, and the AR342 receptacle is a watertight type for ordinary locations. A Cooper Crouse-Hinds junction box or control station should therefore be selected against the area classification drawing, not by enclosure size alone.Ordering Cooper Crouse-Hinds parts: what we need
Send the full catalog number from the nameplate or the casting, including every suffix. For conduit bodies and seals, add the hub size and thread, and state the material, iron alloy or copper-free aluminum. For control stations, list the operators, contact blocks and legend plates. For receptacles, give the amperage, the number of wires and poles, and the mating plug. A nameplate photo and the area classification let us confirm the match before quoting.Browse Cooper Crouse-Hinds products by category: Automation Accessories, Pipes & Fittings, Electrical & Power Modules.
