Contactor ABB ESB20-11N-06, 20A, 1no-1nz, 230V

ABB ESB20-11N-06 Contactor

    ID: 1SBE121111M0611
Rating current: 20 A
Auxiliary contact contact:1 no (one opens frequently) -1 nz (one constant closed)
Control Circuit Voltage (UC): 230V
Rated Working Voltage (Main Circuit):
Main circuit 220V DC
Main circuit 250V AC
Protection level: IP20

Functions and features

Electromagnetic system: When the coil is turned on, the static iron core generates electromagnetic suction, which sucks the iron core, which causes the tentacle system to close and the power supply is connected. When the coil is broken, the suction force disappears.
Contact system: includes main contact and auxiliary contact (one often opens, one often closes) and links with moving iron core to realize circuit control.
Arc extinguishing device(can be equipped): For the contactor with large power, a quick arc interruption device can be installed to quickly cut off the arc to protect the contact.
Insulation shell and accessories: including various springs, drive mechanism, wire column, etc., to ensure the safe and stable operation of the contactor.
Environmental adaptability: It has certain environmental adaptability, such as IP20 protection level, which can prevent the intrusion of external objects and liquid to a certain extent.

Precautionary measures

When using ABB ESB20-11N-06 contactor, please ensure that the voltage of external power supply matches the rated voltage of the contactor to avoid failure caused by overvoltage or underwriting.
The selection of contactor should be made according to the current requirements of the actual load, and the selection is generally selected according to 1.5 times of the rated current of the motor.
During installation and maintenance, relevant safety specifications and operating guidelines should be followed to ensure correct installation and stable operation of the contactor.

Sum up

ABB ESB20-11N-06 contactor is a contactor with rated current of 20A, frequent opening and closing of auxiliary contact, suitable for control voltage of 230V and main circuit voltage of AC 220V/250V. It has key components such as electromagnetic systems, contact systems, possible arc extinguishing devices and insulating shells, which can manage stable and reliable interruption of circuits. During the use process, pay attention to the conformity with the power voltage, reasonably select the contact device model, and follow the safety specifications and operating guidelines.
