WJ Furse, DS Lightning / Surge Arrester 280 V Maximum Voltage Rating 0.032kA Maximum Surge Current Mains Protector / 8472709

WJ Furse Power distribution systems enhanced surge protector - ESP-D/ DS Series. The D/ DS range offers a further enhanced series to the existing ESP range of mains protector range for specific systems, complementing the existing D1 Series. Having a low let through voltage combined with the mains test Type 1, 2 and 3 to BS EN 61643, the D/ DS series is designed for use on low current single phase systems (up to 10A or 32A) to protect against transient over voltages on the mains supply, and offering an increased exposure level covering lighting protection zones (LPZ) 0 -3. It also features a 3 way visual indication of protector status and advanced pre-failure warning, and remote indication facilities to a BMS via a volt-free contact. (DS Version). Features and Benefits:. Combined type 1, 2 and 3 tested protector (to BS EN 61643) Low let through voltages Industry leading, enhanced protection to BS EN 62305 Compact DIN housing 3 way indication facility of protector status and advanced pre-failure warning Remote indication facility (DS Version) Protector ‘s offer repeated protection against transient over voltages. Applications:. The D/ DS range is for low current mains power supply applications, e.g. CCTV cameras, alarm panels, industrial battery chargers and telemetry equipment
