Bowthorpe Distribution Surge Protector 600 Series

Ideal for industrial, commercial and domestic applications, the Distribution Surge Protector 600 (DSP600) provides an economic means of preventing damage to electrical distribution systems from mainsborne transient voltages. These transients may occur as the result of nearby lightning strikes or surges derived from the switching of inductive or capacitive loads.

The DSP600 should be installed at the point of cable entry to a building and at the distribution point for each floor of a multistorey building containing sensitive electrical/electronic equipment.

The DSP600 is normally used as part of a totally integrated surge protection system and as such should be considered as the first line of defence. Local distribution panels and equipment connected 'downstream' should also be protected in order to achieve a systematic and coordinated approach to surge protection.

The DSP600 provides suppression from mainsborne voltage spikes and surges that can occur between phases, phase to neutral, phase to earth and neutral to earth, thus ensuring protection in all modes. This protection is achieved by using carefully matched high energy absorbing elements.

The DSP600 features high surge current handling capability which operates in two stages to ensure continuity of transient suppression. Under normal conditions the DSP600 will automatically reset after clamping smaller, more commonly occurring surges, and a green Light Emitting Diode (LED) indicates that full protection is present. However, should a surge current, in excess of 30kA, appear on the line it will be clamped by the DSP600 but the first protection stage may possibly suffer damage and fail safe.

In this instance the red LED will be illuminated in addition to the green and although the system will still be adequately protected, the unit should be replaced before a further large surge can remove the second protection stage. There is no protection present when only the red LED is illuminated, although unprotected power is still supplied.

An alternative version of the DSP600 is also available which additionally offers a remote signalling facility where volt free terminals (which can be connected as either normally open or normally closed), open or close when the first stage protection is lost, (Red and Green LEDs on), and these can be used to activate a remote indicator such as a lamp or an audible alarm. The switching contacts are completely isolated from the supply and may be used for AC mains voltage 230V RMS 200mA or 30V DC 2 Amp loads.
