Distribution Surge Protector - 600 Series L & N Types

Ideal for industrial, commercial and domestic applications, the Distribution Surge Protector DSP600 Series ’L’ and ’N’ types provide an economic means of preventing damage to electrical systems from mainsborne transient voltages, which may occur as a result of nearby lightning strikes or surges derived from the switching of inductive or capacitive loads

They should be installed at the point of cable entry to a building and at the distribution point for each floor of a multi-story building containing sensitive electrical / electronic equipment.

Units feature high surge current handling capability which operates in two stages to ensure continuity of transient suppression. The ’N’ type is provided with an on-board system of protection status monitoring LED’s, while the ’L’ type is supplied with a remote monitoring unit which allows the unit to be installed in areas that are inaccessible for regular inspection.

Both ’N’ and ’L’ types are supplied with a fault condition indicator to warn of high voltage between neutral and earth lines. They are fitted with remote signalling terminals which can be used to activate for instance a lamp, audible alarm or notify a BMS, to notify if the first protection stage has been lost.

Applications include: Front end of building protection – LV Distribution Panel; Individual protection of critical and costly equipment such as computer systems; Sub-distribution panel protection; Windfarm; Rail

Transient Voltage Suppressors (Modules,Industrial)

Voltage surges, often referred to as spikes or transient overvoltages are typically caused by switching of fluorescent lights, fuses blowing or nearby lightning activity. The worst voltage surges are usually caused by lightning activity and can reach up to 6000V, with current surges of up to 3000A. The maximum size of the voltage and current surges depends on the location within the buildings wiring system. BS6651:1999 Annex C which was replaced in August 2008 by BS EN 62305-4:2006 is complemented by BS EN 61643-11/12 and covers location categories and provides guidance on protection of electronic equipment. For mains power systems, Types I, II and III are used. Surge protection devices not designed to fit into these categories may only provide limited protection and the equipment they protect may suffer damage.
