ESP D1 Series Three Phase Systems Protection

ESP D1 Series Three Phase Systems Protection

ESP415D1 L1_0708

• Very low let-through voltage (enhanced protection to BS EN 62305) between all sets of conductors (phase to neutral, phase to earth, neutral to earth – Full Mode protection)

• Full mode design capable of handling partial lighting currents as well as allowing continual operation of protected equipment
• Repeated protection in lighting intense environments
• Innovative multiple thermal disconnect technology for safe disconnection from faulty or abnormal supplies (without compromising protective performance)
• Three way visual indication of protection status and advanced pre-failure warning so you need to be unprotected
• ESP XXX D1R or ESP XXX D1R/LCD units (where XXX = 208, or 415, or 480) have a remote display that allows the protector to be mounted close to the incoming feed or distribution board with the display being mounted in a visible position e.g. at the front of the panel
• ESP XXX D1/LCD or ESP XXX D1R/LCD units have a backlit LCD intelligent display offering clear status information that can be rotated for the side mounting to facilitate short connecting leads
• Remote indication facility allows pre-failure warning to be linked to a building management system, buzzer or light
• Changeover active volt-free contact enables the protector to be used to warn of phase loss(i.e. power failure, blown fuses etc)
• Flashing warning of potentially fatal neutral to earth supply faults (due to incorrect earthing, wiring errors or unbalanced conditions)
• Through terminal facility allows series connection on low current supplies to eliminate high additive voltage associated with the connecting leads on units installed in parallel
• Compact space saving DIN housing
