Contaktors

Contactors

Contactors are single-pole or multi-pole devices designed for switching DC and AC power circuits and ensuring safe arc quenching during operation.

Contactors are manufactured individually upon customer request.

R-Series Contactors

Depending on the application, R-series contactors can be either normally closed (NC) or normally open (NO).

R-series contactors with different numbers of pole contacts and their configurations (contactors with both NC + NO contacts) are used for controlling power circuits up to 1000 V AC and 1500 V DC. These contactors are assembled from standardized components, which ensures the possibility of fast development of devices according to customer requirements.

R-series contactors are designed for use in harsh operating conditions, in areas where the use of standard equipment is limited.

R-Series Bus Contactors

R-series bus contactors are manufactured in accordance with IEC 60947. They represent a complete range of modular contactors:

• for switching currents from 60 to 5000 A;
• for switching currents at voltages up to 1000 V (AC) and up to 1500 V (DC).

Product Design Capabilities

• combine NO and NC contactors in a single device;
• control both AC and DC power circuits within one device;
• configure various combinations of microswitches (auxiliary contacts) to display the contactor operation on control panels and signaling equipment.

R-series contactors meet special requirements for managing electrical equipment up to 5000 A, with additional requirements to ensure increased reliability in power distribution.
