NEC 500 Hazardous Location Classifications

Class I, Division 1 & 2, Groups B, C, D are for hazardous locations where flammable gases or vapors may be present during normal operations, are normally confined, or not present in ignitable concentrations. Class I hazards are commonly found in petroleum refineries, fuel dispensaries, sewage treatment plants, and processes using chemicals, paints, coatings, or sealants. This rating indicates the electrical device is suitable for use with the following hazardous materials: Group B (hydrogen, butadiene, ethylene oxide, propylene oxide, and acrolein), Group C (ethylene, cyclopropane, and ethyl ether), Group D (acetone, ammonia, benzene, butane, ethanol, gasoline, hexane, methane, methanol, naphtha, natural gas, propane, and toluene).
Class I, Division 2, Groups B, C, D are for hazardous locations where flammable gases or vapors are normally confined or not present in ignitable concentrations. Class I hazards are commonly found in petroleum refineries, fuel dispensaries, sewage treatment plants, and processes using chemicals, paints, coatings, or sealants. This rating indicates the electrical device is suitable for use with the following hazardous materials: Group B (hydrogen, butadiene, ethylene oxide, propylene oxide, and acrolein), Group C (ethylene, cyclopropane, and ethyl ether), Group D (acetone, ammonia, benzene, butane, ethanol, gasoline, hexane, methane, methanol, naphtha, natural gas, propane, and toluene).
Class II, Division 1 & 2, Groups E, F, G are for hazardous locations where combustible dust is present during normal operations, normally confined, or not present in ignitable concentrations. Class II hazards are commonly found in pharmaceutical factories, coal-handling plants, grain elevators, and plants processing flour, feed, or powder. This rating indicates the electrical device is suitable for use with the following hazardous materials: Group E combustible dust (aluminum, commercial alloys, and magnesium), Group F combustible dust (carbon black, charcoal, coal, and coke dust) and Group G combustible dust (chemicals, flour, grain, plastic, and wood).
Class II, Division 1 & 2, Groups F, G are for hazardous locations where combustible dust is present during normal operations, normally confined, or not present in ignitable concentrations. Class II hazards are commonly found in pharmaceutical factories, coal-handling plants, grain elevators, and plants processing flour, feed, or powder. This rating indicates the electrical device is suitable for use with the following hazardous materials: Group F combustible dust (carbon black, charcoal, coal, and coke dust) and Group G combustible dust (chemicals, flour, grain, plastic, and wood).
Class III, Division 1 & 2 are for hazardous locations where ignitable fibers or flyings are present during normal operations, normally confined, or not present in ignitable concentrations. Class III hazards are commonly found in textile mills, lumber mills, and other plants with airborne fibers or sawdust.

Protection Method

Fusible have fuses that blow if the connection experiences an electrical overload or short. They shut off power immediately if there is an electrical malfunction to protect high-current industrial equipment.
Non-Fusible transfer power continuously without interruption. They don't have fuses to protect against electrical overloads or shorts.

Fusible
Non-Fusible

Current Rating

Refers to the maximum amount of current an electrical device can continuously handle without deteriorating or causing damage to downstream equipment.

30 A
60 A
100 A

Number of Poles

This indicates the total number of circuits on an electrical device.

UL Fuse Class

J have a high amperage interrupting rating (AIC) for protecting against short circuits and are ideal for IEC motor starter applications. They are current-limiting to prevent electrical damage by disconnecting circuits before they're exposed to the full magnitude and duration of an overcurrent.

NEMA Enclosure Rating

3 is a safety rating for indoor and outdoor electrical enclosures that specifies a degree of protection against incidental contact, against the entry of solid objects (falling dirt, windblown dust) or water (snow, rain), and against exterior ice formation.
3R is a safety rating for indoor and outdoor electrical enclosures–often called rain-tight or rain-proof–that specifies a degree of protection against incidental contact, against the entry of solid objects (falling dirt, windblown dust) or water (rain, snow), and against exterior ice formation.
4 is a safety rating for indoor and outdoor electrical enclosures with gasketed doors that specifies a degree of protection against incidental contact, against the entry of solid objects (falling dirt, windblown dust) or water (snow, rain, water splashes and sprays), against occasional washdowns, and against exterior ice formation.
4X is a safety rating for indoor and outdoor electrical enclosures – also known as washdown enclosures – that specifies a degree of protection against incidental contact, against the entry of solid objects (falling dirt, windblown dust) or water (rain, snow, water splashes and sprays), against corrosion, and against exterior ice formation.
7 is a safety rating for indoor electrical enclosures that are constructed to keep internal explosions contained when present in hazardous locations.
9 is a safety rating for indoor electrical enclosures that protect against the entry of solid objects (falling dirt, settling dust/lint) that could cause an explosion when present in hazardous locations.
12 is a safety rating for indoor electrical enclosures that specifies a degree of protection against incidental contact and the entry of solid objects (falling dirt, circulating dust/lint) or water (dripping, light splashing).

Horsepower @ 240V AC

refers to the maximum horsepower (motor load) at 240 volts which an electrical device can operate. Electrical devices should have an equal or greater HP rating as the equipment they're powering.

Hazardous Location Disconnect Switches

Available9 products

Hazardous-location disconnect switches provide control of electrical connections in environments where the possibility of flammable gases, vapors, or liquids, ignitable fibers or flyings, or combustible dust may exist under normal and abnormal conditions. They have location ratings that classify their designated operating environment and must be mated with compatible, hazardous-location devices to be compliant with safety standards. Disconnect switches have manual shutdown mechanisms that open and close circuits to disconnect and connect power from single-load industrial equipment, motors, and electrical operations.

Brand

Fusible Disconnect Switches

These hazardous-location disconnect switches have fuses that blow if the connection experiences an electrical overload or short. They shut off power immediately if there is an electrical malfunction to protect high-current industrial equipment in wet and debris-ridden environments. Fuses are sold separately.

Non-Fusible Disconnect Switches

These hazardous-location non-fusible disconnect switches don't have fuses to protect against electrical overloads or shorts. Non-fusible disconnect switches are suitable for applications where downstream equipment has its own overcurrent protection.
