This explosion proof combination switch allows operators to turn fixtures on and off, and utilize 0-10V dimming when fixtures are on, and is a safe and secure method for operators to control fixtures and adjust the brightness of explosion proof lights to best accommodate the situation or workplace while maintaining safety within hazardous environments. This explosion proof combination dimmer/on/off switch is ideal for operators seeking a high quality explosion proof switch rated for use in hazardous areas designated Class I Division 1 & Class 2 Groups C & D, Class II Division 1 & 2 Groups E, F and G and Class III environments. The entire unit is constructed of copper free cast aluminum. This unit is easily wall mounted via integral mounting tabs at two corners of the housing. Operators can choose between two hub sizes of either 1/2" or 3/4" and either a feed through or dead end configuration. This unit is suitable for use in environments where combustible dusts and particulates may be present as well as any other hazardous locations. The EPSW-2G-20A-DRW explosion proof combination dimmer/on/off switch offers operators smooth, flicker-free dimming of lights for precise control of brightness level while maintaining the power delivered to the lamp via a 0-10V rotary switch. The rotary switch also features surge protection technology, advanced heat sinks to extend the service life of the switch and protection from possible interference from radios and other equipment. The dimmer switch is compatible with explosion proof dimmable light fixtures with V+ and V- dimming control wires. This dimmer is not compatible with voltage dimming, the driver/ballast must have 0-10V control wires for dimming to be compatible. The EPSW-2G-20A-DRW also includes an explosion proof feed through tumbler switch that provides a safe and secure method for operators to interrupt power before connecting and disconnecting portable or stationary electrical devices and equipment in hazardous locations. Once the tumbler switch is used to turn on the explosion proof fixture, the dimmer can be used to change the fixture`s brightness output. The EPSW-2G-20A-DRW explosion proof combination switch cover and housing box is constructed of copper free cast aluminum for superior performance and durability.
