Surge arrester, disconnector and plug in one compact module
Get to know this SPD – Surge Protection Device
The Alfacomp SW3300 module was designed to compose electrical command and automation panels and integrates the following functions:
- Sectioning
- Over-current protection by means of fuses
- Over voltage protection by varistors
- Bipolar socket with ground
- Power-on Signaling
By including several functions in a single module, the device simplifies frame assembly and therefore contributes to more compact lay-outs.
Space saving: The SW3300 module advantageously replaces one disconnector + two fuses + one outlet + three SPDs.
Installation: The module is fixed to the DIN rail by a quick-fit plastic clip on the back of the module.
