Built for Hazardous Locations: Why Explosionproof Motor Starters Matter More Than Ever
Reliable motor control is critical when flammable gases, vapors, or combustible materials may be present. Discover why explosionproof motor starters are essential to safer industrial operations.
Walk through any refinery, chemical plant, wastewater facility, or offshore platform and you'll find one thing in common: electric motors are everywhere. They drive pumps, compressors, fans, conveyors, mixers, and countless other critical processes that keep operations moving. But in hazardous locations where flammable gases, vapors, or combustible dust may be present, controlling those motors safely becomes a much bigger challenge.
That's where explosionproof motor starters come in.

What Is an Explosionproof Motor Starter?
At its most basic level, a motor starter is designed to start and stop an electric motor while providing protection against overloads and electrical faults.
In hazardous locations, however, motor starters must do much more than simply control a motor.
An explosionproof motor starter is housed within a specially designed enclosure capable of containing an internal explosion and preventing sparks, arcs, or hot gases from igniting the surrounding atmosphere.
Think of it as an extra layer of protection between electrical equipment and a potentially explosive environment.
Common Applications
Oil & Gas
Motor control for pumps, compressors, and process equipment where flammable gases or vapors may be present.
Chemical Processing
Protection for motors operating around combustible chemicals, vapors, and demanding process conditions.
Offshore & Marine
Rugged motor control designed for challenging environments where reliability and environmental protection are essential.
Power Generation
Hazardous-location motor control for critical equipment and continuous industrial operations.
Water & Wastewater
Motor starters that help protect equipment exposed to moisture, corrosive gases, chemicals, and outdoor conditions.
Industrial Manufacturing
Reliable control for pumps, fans, conveyors, mixers, and other motor-driven machinery.
Why Hazardous Locations Demand More
In a typical industrial environment, a motor starter is primarily focused on motor protection and operational control.
In a Class I Division 1 environment, however, the stakes are much higher.
These locations are defined by the possibility that flammable gases or vapors may be present during normal operating conditions. Under these circumstances, even a small electrical arc or spark can become an ignition source.
That means motor control equipment must be engineered not only for performance but also for safety.
Protect people.
Protect equipment.
Protect operations.
More Than Just Starting a Motor
Today's explosionproof motor starters provide several important functions beyond simply turning a motor on and off.
Modern solutions often include:
By integrating these functions into a single explosionproof assembly, facilities can improve reliability while simplifying installation and maintenance.
The Growing Popularity of Combination Motor Starters
One of the fastest-growing categories in hazardous location motor control is the combination motor starter.
Instead of requiring separate components for motor control, disconnecting, and protection, combination starters integrate multiple functions into a single enclosure.
The Result?
Less complexity. Fewer components. Simplified installation. Reduced maintenance.
For contractors and facility operators, that translates directly into lower installation costs and reduced downtime.
Combination motor starters are particularly attractive in retrofit projects where available space may be limited and installation efficiency is a priority.
Why Reliability Matters
In industries like oil and gas, petrochemical processing, and power generation, downtime is expensive.
A failed motor starter doesn't just affect one piece of equipment. It can disrupt entire processes, impact production schedules, and create costly maintenance events.
That's why reliability remains one of the most important selection criteria for hazardous location motor control equipment.
Facilities need products capable of withstanding:
A rugged explosionproof enclosure is often the first line of defense against these demanding conditions.
