EBM Series Explosionproof Disconnect Switches - 1

EBM Disconnect Switches and Enclosures 600 VAC Heavy Duty DC using 2 AC Polyphase poles only With Switch Applications: EBM series hinged cover disconnect switches are used: • To disconnect motor, lighting and other circuits. • In locations made hazardous by the presence of flammable gases or vapors or ignitable dusts. • Indoors or outdoors in damp, wet and dirty locations, or in areas where frequent washdowns, heavy rain or water spray is prevalent. • To provide disconnect means and short circuit protection (fusible version). • On switchracks or other assemblies where it is desired that motor control be centrally located. Features: • Rugged corrosion resistant cast copper-free aluminum construction (less than 0.4 of 1%). • Switch operating handle is located through the right side wall of the body, permits visual confirmation of correct alignment and operation. • Total compliance to the wiring end room requirements of the National Electrical Code. • Semi-clamshell enclosure design, with an external flanged ground joint between body and cover makes interior components more accessible. • Minimum enclosure-to-enclosure spacing with little interference between the opened cover and an adjacent enclosure. • Stainless steel hinges allow the cover to swing well out of the way. • Stainless steel quick release captive hexhead cover bolts. Stainless steel springs provide clear indication that cover bolts are fully retracted from the body. • Switch operating handle can be padlocked in either the "ON" or "OFF" position. • Neoprene cover gasket permanently attached to the cover seals out moisture. • Bodies have top and bottom drilled and tapped conduit entrances for power and conduits. Removable reducers are supplied as standard, to accommodate smaller size conduits. All conduit entrances are plugged. • Tap on mounting feet.
