Explosion‑proof motor starters provide a fully enclosed, flameproof solution for operating motors in hazardous locations. These starters are built inside certified enclosures designed to contain internal ignition and prevent flame propagation into the surrounding atmosphere. Control Innovations supplies explosion‑proof motor starters suitable for a wide range of classified areas and application requirements.
An explosion‑proof motor starter provides safe motor control in hazardous locations where ignitable gases or vapors may be present. The flameproof enclosure contains arcs, sparks, or heat generated during motor starting, ensuring compliance with hazardous‑area requirements.
Hazardous‑Area Ratings
Explosion‑proof motor starters can be installed in:
- Class I, Division 1
- Class I, Division 2
- Class I, Zone 1
- Class I, Zone 2
Most flameproof enclosures are certified for Class I, Division 1, making them suitable even when installed in Division 2 or Zone 2 areas.
Key Features
Control Innovations explosion‑proof motor starters typically include:
- Flameproof enclosure rated for hazardous locations
- Reversing or non‑reversing motor starter
- Optional pilot devices, disconnect handles, and viewing windows
- Lockable disconnect options when required
- Configurable for local START/STOP operation
- Manual motor starter options up to 25 HP at 600 V or 480 V
This provides a rugged, compliant motor‑starting solution for hazardous environments.
Manual Motor Starter Option
For applications requiring only local control, a manual motor starter in an explosion‑proof enclosure may be a more economical choice. These units can be configured up to:
- 25 HP at 600 V
- 25 HP at 480 V
They provide simple, reliable START/STOP functionality in hazardous locations.
Installation Considerations
Control Innovations can assist with:
- Selecting appropriate cable types and connectors
- Recommending sealing fittings and installation methods
- Ensuring compliance with hazardous‑area wiring practices
Because most flameproof enclosures are Division 1 rated, all cable glands must be sealing‑type and approved for Class I, Division 1 installations even when the panel is used in Division 2 or Zone 2 areas.
Additional Options
Explosion‑proof motor starters can be customized with:
- Pilot lights
- Pushbuttons
- Disconnect handles
- Viewing windows
- Auxiliary control features
These options allow the starter to be tailored to site‑specific operational needs
