Contactors are electromagnetic

Contactors 0, 1, 3, 4 sizes are intended for switching of chains constant (and variable for 1 size) current of crane and traction electric equipment.

Scope:
City electrotransport (trolleybuses, trams, subway), heavy-load cars, locomotives.
- KTK-0, KTK-1 - crane and traction electric equipment of trolleybuses, trams, subway cars,
- KTK-3, KTK-4 - crane and traction electric equipment of trams, heavy-load cars, conveyors, trolleybuses, locomotives,
- KPD-113E, KPD-114E - crane electric equipment,
- KPP-113, KPP-114 - traction electric equipment of trolleybuses, trams, the subway, heavy-load cars,
- TKPD-114V - traction electric equipment of locomotives.

Main consumers:
Metallurgical, machine-building enterprises, city electrotransport, railway transport.

Types of a climatic modification: UHL2, U2, HL2, T2.

Distinctive features:
- optimum scheme of a rupture of the main contacts,
- modern the design and materials of dugogasitelny devices providing a big switching resource
- the maximum speed, high mechanical wear resistance of magnetic system and the including coil,
- the high degree of reliability confirmed with resource tests and data of operation
- the minimum expenses at installation and service,
- existence of execution of contactors with auxiliary contacts for low-exact (current 15 ma and more, voltage is 24 V and more) alarm chains.
