The Allen-Bradley 800H-HP4803KL8AAXX hazardous-location keyed selector switch is a 30.5 mm, Type 7 & 9 explosion‑proof control device with a two‑position, spring‑return action. It uses a D020 keyed cylinder that returns from the right position and locks in the left position to regulate operator access in demanding environments. Included are two 800T-XA contact blocks (each provides 1 normally open and 1 normally closed contact), with screw-terminal wiring for straightforward installation, and a rating up to 600 VAC or 600 VDC and a thermal continuous current of 10 A AC / 2.5 A DC. The unit features a 30.5 mm mounting hole, operating temperature range of -20°C to +40°C, and a minimum mechanical life of 200,000 operations. It is commonly used in hazardous-area control stations, motor control centers, and process automation across oil and gas facilities, chemical plants, refineries, mining operations, and wastewater treatment plants.
