ZKF Series Vaccum auxiliary switch ZKF6-8W

Specifications

 Adaptable

The switch with mechanical contact sometimes causes stiff work when the contact is corroded quickly in corrosive environment, such as F series.Different from F series, ZKF series’ contacts are enclosed in vacuum tube, so that they can still have good making and breaking capacity even it’s surrounded with dust, damp, and corrosion. To meet various requirements from clients, ZKF series are of different installing ways, different angles of rotation, and different central heights. ZKF series can replace F series, excludes the situation of being the main auxiliary contacts for the breaker.

Long Lifetime & Antijamming

The reed switch in ZKF series can be used for over 100,000 times, and its lifetime is much longer than the mechanical contacts. The permanent magnet steel, which controlling the making and breaking process, is made of rear earth magnet, and it’s ferromagnetic. The configuration of the switch can resist the interference from the magnetic field and electric field effectively.

High Mechanical Strength & little overhanuling

The parts of F series are loose that they often require overhauling. Differently, ZKF series uses epoxy to seal the center part-vaccum reed switch with connection bar into the stator. With the high mechanical strength, it saves trouble because loosing contacting happens rarely.

Good Electrical Contact

F series auxiliary switch adopts mechanical friction contacting mode, and the friction area is usually blackened because of the electric arc, which seriously influences the contact. However, the contacts of ZKF series work under vacuum or inert gases. And create no electric arc under rated current to make sure good contact.
