ZKF2-C1

The superiority of series ZKF vacuum auxiliary switch.

1.      Adaptable

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

2.      Long Lifetime & Antijamming

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

3.      High Mechanical Strength & little overhauling 

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

4.      Good Electrical Contact

Series F auxiliary switchs uses contact style of mechanical friction, and the contact area is usually blackened because of the electric arc, which seriously effect the contact. However, the contacts of series ZKF work under vacuum or inert gases, and creat no electric arc under rated current to make sure good contact.
