ESP D1 Single Series Systems Protection

ESP D1 Single Series Systems Protection


• 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 lightning currents as well as allowing continual operation of protected equipment
• Repeated protection in lightning intense environments
• Innovative multiple thermal disconnect technology for safe disconnection from faulty or abnormal supplies
• Three way visual indication of protection status and advanced pre-failure warning so you need never be unprotected
• Remote indication facility allows pre-failure warning to be linked to a building management systems, buzzer or light
• Changeover active volt-free contact enables the protector to be used to warn of phase loss (i.e power failure, blown fuse 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 connecting lead on units installed in parallel
• Compact space saving DIN housing
