Modular Contactor For Installation Into Distribution Board
Modular contactors are used for installation in consumer units in dwellings, business premises, hotels, hospitals, shop�ping centres, sport centers, production halls, warehouses etc.
They are used for remote switching and automatic control of electric devices and equipment, such as:
�all types of pumps
�single-phase and three-phase motors
They excel in silent operation, long mechanical life time and high quality.
The contactors are designed for mounting on 35 mm mounting rail in accordance with the EN 60715 standard and they can be leaded by means of lead covers. The auxiliary contact block is available for signalization and ventilation module is available for preventing exceeded heating when contactors are used side-by-side.
All contactors have degree of protection IP20.
Besides the basic AC controlled types R20, R25, R40 and R63, types with increased silent operation RD20, RD25, RD40 and RD63 are available. Due to DC magnet and rectifier enable DC and AC voltage control. Surge arrestor is built in for over voltage protection.
Types R20-R, RD20-R, R25-R and RD25-R are upgraded versions of basic types of modular contactors. Besides basic functions they enable manual control with a handle.
Description of the handle positions:
�A: the contactor functions as an installation contactor without manual control
�O: permanently OFF
�I: manual shifting the handle from position A to I causes the contactor to close; when control voltage is applied, the handle is automatically set to position A.
Types RD20-R and RD25-R are provided with a varistor for over voltage protection and a rectifier, which enables con�trol with AC and DC voltage.
Contactors with manual control enable:
�switching depending on tariff (selection of the most convenient tariff)
�switching when control voltage is not applied
