A Div 2 Power Distribution Panel provides safe, reliable power delivery in hazardous locations where flammable gases or vapors may be present under abnormal conditions. Built in a NEMA 4X enclosure with a hermetically sealed disconnect, the panel delivers clean low‑voltage power without requiring a purge system, making it a compact and cost‑effective solution for classified areas.
Purpose
Div 2 power distribution panels are designed to bring utility power into hazardous locations and convert it into stable low‑voltage output for instrumentation, controls, and small electronic loads. These panels:
- Accept 120 VAC or 240 VAC supply power
- Use a sealed, Division‑rated disconnect (e.g., Stahlin‑style hermetic design) to eliminate the need for purge/pressurization
- Provide 24 VDC power through an industrial electronic power supply
- Deliver safe, compliant power distribution in Class I, Div 2 environments
This makes them ideal for wellsites, pump skids, analyzer shelters, and any area requiring low‑voltage power in a hazardous zone.
Key Features
The panel focuses on safe isolation, clean power conversion, and reliable operation in harsh environments. Typical features include:
- Hermetically sealed Div 2 disconnect to safely isolate incoming power
- NEMA 4X enclosure for corrosion resistance and outdoor durability
- Industrial‑grade 24 VDC power supply sized for instrumentation and control loads
- Terminal blocks for clean field wiring and organized distribution
- Optional surge protection, fusing, or circuit breakers for downstream devices
These features create a robust, low‑maintenance power source for hazardous‑area equipment.
Hazardous Location Compliance
The sealed disconnect is the core element that allows the panel to operate in Div 2 without purge requirements. This design:
- Prevents arcing components from exposing the environment to ignition sources
- Eliminates the cost and complexity of purge/pressurization systems
- Simplifies installation and reduces long‑term maintenance
This keeps the panel compliant while remaining compact and easy to deploy.
Integration & Application
Div 2 power distribution panels support a wide range of field devices and small control systems. They can:
- Power transmitters, analyzers, RTUs, radios, and small PLC/HMI systems
- Feed remote I/O drops or instrumentation clusters
- Serve as a local power hub for skids, shelters, and modular equipment packages
This flexibility makes them a practical building block for hazardous‑area automation.
Operational Reliability
Reliable power is essential in Div 2 environments. These panels:
- Protect equipment from overloads, surges, and environmental exposure
- Provide stable 24 VDC output for sensitive electronics
- Offer clear local isolation for maintenance and troubleshooting
This ensures safe, predictable operation even in demanding field conditions.
