Surge protection devices (SPDs) play an essential role in protecting sensitive electrical and electronic equipment from damage caused by overvoltages or other electrical power surges or spikes. Alan Reed, low voltage product manager at Cooper Bussmann, takes a look at the latest developments in surge protection for a wide range of applications 
Overvoltages, electrical power surges or spikes are fast, short duration electrical transients in an electrical circuit. It is generally thought that up to 80% are generated from internal sources such as inductive load switching and normal equipment operations, while around 20% derive from lightning strike and power utility switching. The result can be cumulative equipment damage and possible premature failure, expensive system resets, downtime and data losses. Lightning strikes can cause catastrophic equipment failure, resulting in longer-term business disruption, plus expensive equipment repair and replacement costs.

Mersen (previously Ferraz Shawmut) is the inventor of TPMOV, a technology that disconnects metal oxide varistors at their end-of-life via a shield to protect them against damage from overheating. This patented, fully-standardised technology has enabled Mersen to launch a line of UL 1449 3rd edition approved Surge-Trap modular surge protective devices (SPDs) on the North American market followed by a line of SPDs for other markets and which also meet the requirements of IEC 61643-1.
Surge-Trap SPDs feature a failsafe design that protects them against disruptive, dissipative and destructive damage caused by transient surges in low-voltage equipment.

Schneider Electric has launched the latest addition to its successful Qwikline range of  consumer units, the SQOSR4R4.
The new consumer unit’s dual RCD 4+4 configuration is particularly suited to smaller properties such as flats, where space is limited. This ensures smaller residential and light commercial properties can still benefit from the features of the Qwikline range without losing too much space to their consumer unit.

Now available from Martindale Electric is the new SB13 Safebreak Socket Test Adapter, an accessory for electricians who carry out electrical installation testing.
Eliminating the need to remove the wall socket faceplate, the compact and robust SB13 enables electricians to safely and quickly make tests at wall socket outlets. Providing good connection to the wiring installation using standard 4mm test probes, R2 and R1 and R2 measurements are quickly identified, saving electricians valuable time and money.
Suitable for use with any meter having industry standard 4mm plugs, the SB13 from Martindale Electric speeds up periodic 17th edition testing and Part P testing of electrical installations.
