Design Features - EBMX Clamp
- The clamp housing significantly reduces housing entry time and reduces the likelihood of missing, stripped or broken bolts.
- 65 kAIC at 480 V rated frame voltage for high breaking capacity applications
- Temperature range from -50°C to +60°C for extreme conditions
- Magnetic, thermal-magnetic and electronic tripping devices for short-circuit and overcurrent protection
- Bimetallic and electronic/semiconductor overload protection options
- A normally open (NO) holding contact is included as standard.
- Up to six coverage operators for various applications
- The side switch handle provides visual confirmation of proper operator alignment when the cover is open and can be locked in the "ON" or "OFF" positions to comply with OSHA requirements.
- Neoprene cover gasket provides NEMA 4X protection when handling the hose.
- Maximum compliance of the electrical wiring room with the National Electrical Code ensures easy and safe installation*
- Rugged, corrosion-resistant, copper-free cast aluminum construction provides NEMA 4X protection.
- The semi-clamshell design of the housing with an external flange joint between the housing and the cover provides improved access to internal components.
- Minimum distance between housings with a small gap between the open lid and the adjacent housing
- Pre-drilled mounting plate for easy installation of starter and switch
- Removable mounting feet
- Steel brackets are included as standard for lifting during installation.
- Enclosures have drilled and tapped entries at the top and bottom for power and control wiring; removable adapters are supplied as standard to accommodate smaller conduit; all conduit entries are plugged.
*Standard factory wiring between starter and circuit breaker - consult factory for any additional wiring requirements
