SW150

NO - SP - ST

The SW150 is designed for use in telecommunications and power distribution applications where an uninterrupted current load is switched.  These contactors are primarily for use with Direct Current loads but can also be used with Alternating Currents.

The SW150 features double breaking main contacts with silver alloy tips which are weld resistant, hard wearing and have excellent conductivity.  Silver plating on the main contacts is standard for the SW150, however optionally it can be excluded from the specification.  The SW150 is a compact contactor which can be busbar mounted vertically or horizontally, if mounted vertically the coil should be at the bottom.  If the coil is required at the top, we can adjust the contactor to compensate for this.
