STANDARD SW2000
NO - SP - ST
The SW2000 is designed for use in telecommunication and power distribution applications where an uninterrupted load is switched. These contactors are primarily for use with Direct Current loads but can also be used with Alternating Currents.
The SW2000 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 SW2000, however, optionally it can be excluded from the specification. This compact contactor can be busbar mounted vertically or horizontally, however if mounted vertically, the coil should be at the bottom. Optional extras include auxiliary switches, brackets, coil finishes and magnetic latching – this allows the contactor to remain closed while consuming no coil power.
