ESP DCD1 Series

The ESP DCD1 series is a combined Type 1, 2 and patented Enhanced Type 3 tested protector (to BS EN 61643) for use on DC power distribution systems primarily to protect connected electronic equipment from transient overvoltages on the mains supply, e.g. computer, communications or control equipment.

For use at boundaries up to LPZ 0 to protect against flashover (typically the main distribution board location, with multiple metallic services entering) through to LPZ 3 to protect sensitive electronic equipment.

Features & benefits

• Very low let-through voltage (enhanced protection to IEC/BS EN 62305) between all sets of conductors (positive to negative, positive to earth, negative 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 (without compromising protective performance)
• 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 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.)
• Through terminal facility allows series connection on low current supplies to eliminate high additive voltage associated with connecting leads on units installed in parallel
• Compact space saving DIN housing
