|The Larson Electronics EPFDS-400A-3P-3X400A.600V-FA Explosion Proof Fused Disconnect is designed for use in Class I, II and III environments. Equipped with fast-acting fuses, this 3-pole unit contains three, 400-amp 600V fuses and three NPT hubs. The explosion proof disconnect offers instant response to surges and electrical spikes, making it ideal for resistive circuits in flammable work sites. *PLEASE NOTE: ANY FREE SHIPPING OFFERS DO NOT APPLY TO EXPLOSION PROOF ENCLOSURES* The EPFDS-400A-3P-3X400A.600V-FA ensures active protection of electrical systems in combustible facilities. Rated at 600V AC, this fused unit contains three, 400-amp 3-pole 600V fast-acting fuses. These explosion proof disconnects are sensitive to electrical pulses, which provide peace of mind for operators working with sensitive equipment, such as laptops and electronics. Choosing between a time-delay fuse and a fast-acting fuse highly depends on the type of system or device requiring protection, as both protective methods are effective (one is not superior over the other). The explosion proof disconnect switch/breaker is constructed of cast aluminum and stainless steel cover bolts. The external on/off lever can be locked into the "on or "off" position with room for up to three padlocks for superior security. A gasketed flange with O-ring (in the side bolt circle) is available for protection from the ingress of moisture. Hubs: For completing electrical connections, three NPT hubs are provided on the enclosure. Two 3" NPT hubs are located at the top of the unit; and one 0.5" NPT hub can be found at the bottom of the disconnect, with a wire size compatibility of #2-600MCM. Mounting: Operators can mount the explosion proof disconnect on flat surfaces. Applications: Sensitive equipment, electronics, LED lighting systems, computers, petroleum refineries, chemical and petrochemical plants, storage areas, and other processing facilities where hazardous substances are handled or stored.|
