Static Charge Grounding Relays are certified Intrinsically Safe devices enclosed in explosion-proof housings, designed to provide reliable protection against fires or explosions caused by static charge discharge during tanker loading and unloading operations. Serving as critical interlocks in hazardous environments, these Relays ensure that the loading or unloading process starts only after the static charge on the tanker body is securely grounded. This safety system effectively minimizes the risk of sparking in explosive atmospheres, enhancing operational safety.
