Bowthorpe Plug-in Surge Protection SPM Series


The SPM series of modular surge protection devices provides protection of equipment connected to incoming low voltage AC power supplies against the damaging effects of transient over voltages caused by local lightning strikes, or the switching of electrical inductive or capacitive loads. SPM devices are ideally suited for the protection of electrical distribution systems in buildings, generator set standby power supplies, combined heat and power, and co-generation applications against corrupted data and software, equipment failure and structural damage.

The SPM comprises separate 1, 2, 3 or 4 modular DIN rail connection bases, and a comprehensive range of 6kA or 40kA replaceable plug-in protection modules with integral mechanical status indication, which simply plug in. Connection bases are available with, or without, an additional remote indication facility for the communication of status information into building management or SCADA systems. For installation convenience, the SPM series allows the selection and configuration of any number of modules to suit individual applications, or complete assemblies of the most popular configurations.

The SPM series provides protection of expensive power assets against the damaging effects of mainsbourne transients through carefully matched high energy absorbing elements. Each type of plug-in protection module has a colour coded label to enable easy identification, eg: 6kA modules are purple, 40kA modules are blue, and neutral/earth modules are green. The highly flexible characteristics of the SPM allow the selection and configuration of any number of modules to suit the surge protection requirements of individual applications.

DIN Rail Modular Connection Bases

The SPM series offers DIN rail mount connection bases in 1, 2, 3 or 4 modules, into which the chosen surge protection module(s) simply plug-in. Connection bases can be supplied either with, or without, additional remote indication facility for communication of status information into building management or SCADA systems.

6kA SAD Plug-in Surge Protection Modules

Silicon avalanche diode (SAD) models conduct maximum current without any increase in clamping voltage. The robust nature of this component technology offers long product life expectancy, ideally suited for high risk mobile telecom or other mission critical applications. 6kA modules are available in phase, and neutral to earth versions.

40kA MOV Plug-in Surge Protection Modules

Metal oxide varistor (MOV) models provide excellent clamping of transients and are ideally suited for high/medium/low risk applications, as detailed in EN 61643-11:2002. 40kA modules are available in phase, and neutral to earth versions.

6kA and 40kA Neutral to Earth Plug-in Surge Protection Modules

SPM series offers neutral to earth protection for use in conjunction with 6kA SAD or 40kA MOV surge protection modules. Surge voltages affect system earth to neutral to a lesser degree than the main incoming AC supply, but should be protected against damaging transients.

Complete Assemblies

For installation convenience, the SPM series offers the most popular configurations of connection bases and surge protection modules as complete protection assemblies.
