T1SP Type I Class I
Designed for use on the boundary between LPZ 0 and 1, the T1SP range of surge arrestors are a Class I and II protective device available in both single phase and three phase configurations. For use on installations such as commercial/industrial premises, schools, hospitals and anywhere else where there is a perceived risk from lightning strikes and transient voltages (10/350µs).
DSP Series Type I1 Class Il
The DSP Series surge arrestors are a robust Class II arrestor (8/20µs) available in single and three phase configurations. The units feature a two stage arrestor that gives your system double the protection of normal “plug in” surge arrestors. This allows identification of the possible lack of protection to be caught early and preparations made for the replacement unit to be installed (all while the system is still protected). Suited to all commercial/industrial projects as well as schools, hospitals, etc.
SPM Series Type I1 Class I1
Featuring a pluggable surge protection module, the SPM Series of arrestors are ideally suited for most commercial/industrial applications. The pluggable aspect allows the replacement of the modules without having to disconnect cabling. The units are rated at Class II protection levels (8/20µs) and can be configured in various formats to cater for most earthing systems (TNS/TNC). With a DIN rail mount and each module being DIN width, placement of arrestors in consumer units and Type B distribution boards is easily achieved.
T3SP1/1.5/3.0/230S Type I1I Class IlI
A Class III surge arrestor that is a flexible solution to protecting individual pieces of equipment. Perfectly suited to protecting ring mains and individual sockets, switch fuse spurs, lighting, fire alarm panels, CCTV cameras, etc. Its small size means that it can be mounted in confined spaces and the audible alarm will indicate if the arrestor needs to be replaced. The T3SP1/1.5/3.0/230S will offer 10m of protection either side of the device it is installed on.
SPLB1/13 Type I1I Class I1I
The ‘Spur Protector’ SPLB1/13 provides an economic means of preventing damage to sensitive electronic equipment on individual ring mains from the dangers of transients, which can occur as the result of a nearby lightning strike or surges derived from the switching of inductive or capacitive loads.
