SW500 Datasheet | Albright

SW500 Single Pole Single Throw Normally Open (Part of the Busbar Series) The SW500 is designed for use in telemunication 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. - Uninterrupted current - no or infrequent load switching requirements (maintains lower contact resistance).

The SW500 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 SW500, however, optionally it can be excluded from the specification. This pact...
