SW260

NO - SP - ST

The SW260 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 SW260 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 SW260, however, optionally it can be excluded from the specification.  This compact contactor can be busbar mounted vertically or horizontally, but if mounted vertically, the coil should be at the bottom.  Optional extras for the SW260 include auxiliary switches, brackets, coil finishes and magnetic latching which allows the contactor to remain closed while consuming no coil power.

Please note, although still available the SW260 has been superseded by the SW300.
