Appleton™ explosionproof, dust-ignitionproof EBC Bolt-On Series line starters combine thermal magnetic circuit breakers and magnetic motor starters to provide across the line starting and stopping of polyphase AC motors, branch circuit protection, disconnect means, and motor running overcurrent protection.
The Bolt-On Series incorporates compact, ruggedly built enclosures with hinged, removable covers secured by stainless steel bolts.
Features
Mating surfaces are precision-ground to explosionproof specifications.
All starters are 3-pole and equipped with overload protection.
Optional accessories provide for start-stop control, either remotely or on the enclosure.
Removable hinged cover with captive, hex head bolts allow fast, easy release of cover with a few turns on each.

Accessories may be factory installed or added later in the field.
Enclosures feature compact design. Four removable mounting lugs have pear shaped holes, permitting easy installation for rack or individual mounting.
Standard conduit openings are located top and bottom.
Openings for drain and breather or control circuit are also provided, with close-up plugs.
Interior components are mounted on easily removable pan. Complete removal of this assembly gives full access to enclosure interior for wire pulling. Room for a control transformer is provided in all EBC series enclosures.
