Product Description

General Instruction
FC series auxiliary switch is one of the auxiliary components for the set of highvoltage
equipments. It adopts the cam composition and magnetic quenching
method, and with multitudinous contacts--the feature of cam switch. Meanwhile,
it has the function of increasing the contact quantity by adding the accessories
to meet customer`s needs.
The contact section of FC series auxiliary switch adopts the advanced
permanent magnet magnetic quenching technic to restrain the electric arc in
breaking off the circuit, which enhances the breaking capacity of the contacts
and solve the industry problem that is auxiliary switch is quite hard to break off
in DC circuit. The permanent magnet which generates high magnetic field
intensity guarantees the stability and perdurability of the magnetic field.
Besides, FC series auxiliary switch is also applicable both for controlling switch
on & off functions, interlocking, signal circuits of high-voltage-switch driving
mechanism and for conversions or group switches.
