EHDB280 ABB Spectrum Drive Contactor

ABB EHDB280 is a drive contactor in the Spectrum series. The following is its introduction:

Features

Large current carrying capacity: The rated current is 280A, which can meet the control requirements of equipment such as large power motors. It can be used to control motors of large fans, water pumps, compressors and other industrial equipment.

Multiple coil voltages are available: Common ones are 110V, 120V AC and 240V AC, etc., which can adapt to different control circuit voltage requirements, and facilitate users to choose according to actual power supply conditions.

Applicable to specific systems: Designed specifically for solid-state DC speed control drive systems, it has good compatibility and matching with such systems, and can effectively realize the control and protection of motors in drive systems.

Reasonable structural design: For example, the air electromagnetic structure has good electromagnetic performance and mechanical stability, ensuring that the contactor can work reliably during frequent operation and long-term operation, reducing the probability of failure.

Technical parameters

Rated voltage: Generally applicable to higher voltage levels, such as 600V DC and below circuits, depending on different application scenarios and configurations.

Number of poles: There are different configurations such as 2 poles and 3 poles. The appropriate number of poles can be selected according to the needs of the actual circuit to achieve control of motors or loads with different phases.

Application field

It is mainly used in occasions where DC speed regulation drive systems need to be accurately controlled and protected, such as industrial automation production lines, elevator control systems, textile machinery, papermaking machinery and other fields. In these application scenarios, it can be used in conjunction with control systems such as PLC and DCS to achieve control functions such as start and stop, speed regulation, forward and reverse rotation of the motor, and when the motor is overloaded, short-circuited or other faults occur, the circuit is cut off in time to protect the safety of the equipment.
