ABB Electrical 1SBL141001R8810 Auxiliary Block Contactor

ABB Electrical 1SBL141001R8810 Auxiliary Block Contactor

Basic Information

Model No.: 1SBL141001R8810 belongs to ABB A series AC contactor.

Place of origin: Sweden.

Technical Parameters

Voltage: The rated voltage of the control coil is 230 - 240V 50Hz / 240 - 260V 60Hz, and the rated voltage of the contacts can be up to 690V.

Current: The rated operating current of the AC-3 varies at different voltages, e.g. 9A at 220/230/240V and 7A at 690V. The rated current for general use is 25A, and the controllable power varies accordingly at different voltage levels, such as 4kW at 415V and 5.5kW at 690V.

Contact configuration: the main contact is three-pole, the number of normally open contacts is 3, the number of normally closed contacts is 0; the number of auxiliary contacts is 1 normally open, 0 normally closed.

Functional characteristics

Control function: It is mainly used to control the on-off of three-phase AC circuit, and is suitable for all kinds of equipments that need to control three-phase power supply, such as three-phase motor, three-phase heating equipment, and so on. By controlling the energising and de-energising of the coil, the main contact is closed or disconnected, thus realising the control of the load.

Auxiliary Control Expansion: The auxiliary contacts can be used to expand the control functions and realise complex control logics such as forward and reverse motor control, star-delta start control, etc. They can also be used for signal feedback to the control system. They can also be used to provide feedback to the control system on the contactor's engagement and release status for system monitoring and troubleshooting.

Compatibility and Integration: Compatible with other ABB electrical products and common electrical equipment, it can be easily integrated into an electrical control system with main contactors, PLCs, relays, sensors and actuators to perform complex control tasks.

Application Areas

Industrial automation: in automated production lines, it can be used to control the operation of conveyor belt motors, robotic arm motors and other equipment; in machine tool control, it can be used to control cooling pumps, tool feed motors and so on.

Building electrical system: in the three-phase lift control system, it can be used to control the three-phase motor operation of the lift car; in the HVAC system, it can be used to control the starting and stopping of three-phase air-conditioning unit fans, compressors and other equipment, and the switching of operating modes.

Power system automation: It is used for signal processing and control logic in power facilities such as substations, distribution rooms, etc., and cooperates with the main contactor to achieve safety control and condition monitoring of power equipment.
