SW150 & SW250 Heavy Duty D.C. Contactors for Power Distribution Centres ji&biùj/iZ International announces two new additions for use within the Télécommunications market: The SW150 & The SW250 These busmountable compact contactors follow the recognised design of the SW260 series of contactors. The majority of the features available on the SW260 series are also available on these two new ranges of Contactors: • Coil Suppression & Auxiliary Contacts • Mounting bracket kits are available for alternative mounting arrangements. In addition, both types are available with Magnetic Latching which enables them to remain closed whilst consuming no coil power.
