  • What type of switch should be used in an explosion-proof distribution box

    What type of switch should be used in an explosion-proof distribution box

    Explore top-rated explosion‑proof level switches, float switches, limit switches, and pressure switches tailored for hazardous environments like oil & gas, chemical plants, and industrial zones. An explosion-proof switch is a specially designed electrical switch that can safely operate in explosive atmospheres. With the ability to provide QUAD labeling for UL, CSA, ATEX and IEC Ex d requirements, this series of disconnect switches is suitable for world wide. This guide explains the differences between explosion proof (Ex d) and intrinsically safe (Ex ia) pressure switches, how each protection method works, and the key factors to consider when selecting a product for safety critical environments. To comply with explosion proof requirements the GSX has flame paths within the housing, which cool exploding gases below the ignition temperature before. But in hazardous areas where flammable gases, vapours or dust may be present, these switches must be housed in robust, explosion proof enclosures and carry ATEX and IECEx certification to prevent ignition of the surrounding atmosphere.
