Bulletin 4983-DS off ers a number of options to meet your basic surge protection needs. The 4983-DS products are connected in parallel and use a MOV to clamp high voltage surges. The 4983-DS is primarily used in the main electrical panel for the protection of single and 3-phase systems.

Novaris SDD DINsafe Surge Diverters offer powerful performance at domestic MSB and industrial DBs. The SDD diverters are housed in DIN compliant, failsafe metal enclosures and are fully compliant to AS/NZS1768-2007 and to AS/ NZS3000 wiring rules.

Novaris MULTIMOV MSB surge diverters offer unsurpassed safety, quality and reliability in protection for your electrical system. MULTIMOV surge diverters are an ideal point-of-entry protector for all industrial, commercial and communications applications.

SPD PLUGGABLE 2P 40KA 1.5KV

The Novaris SL range of plug-in signal line protectors provides surge protection for most twisted pair signalling schemes. Ideal for the protection of PLCs, fire and security systems, telecommunications and telemetry systems, railway signalling.

The IS-SL range provides protection to most analogue and digital interfaces. Commonly analogue inputs and outputs are the most susceptible to damage from surge and transients induced onto the signal lines. The IS-SL range is designed exclusively for low current applications less than 350mA. For applications requiring a higher current rating Novaris recommend the IS-SSP6A range. The Novaris IS-SL range can are suitable for both input and output applications.

Voltage surges, often referred to as spikes or transients are typically caused by switching of fluorescent lights, fuses blowing or nearby lightning activity. The worst voltage surges are usually caused by lightning and can reach up to 6000V, with current surges of over 3000A. The maximum size of the voltage and current surges depends on the location within the building s wiring system. BS7671: 2011 Amendment 1 Sections 443 and 534 cover risk assessment and provides guidance on protection of electronic equipment for installation engineers to follow. The fullest information on lightning and surge protection comes from the BSEN 62305 series of standards.
