£91.41
The ABB ASL12-30-01-81 is a compact three-pole DC-operated contactor designed for controlling three-phase motors, power circuits and non-inductive or slightly inductive loads. As part of the ABB ASL contactor range, it combines three normally open main contacts with one built-in normally closed auxiliary contact.
This contactor features a low-consumption 24 V DC coil suitable for direct control from compatible PLC outputs. Its solid-core magnet circuit provides dependable DC operation, while the compact block-type construction supports straightforward integration into industrial automation and motor-control panels.
With an AC-3 operational current rating of 12 A at 220–415 V and a motor rating of 5.5 kW at 400 V, the ASL12-30-01-81 is suitable for switching industrial motors and power circuits. The contactor supports operational voltages up to 690 V and includes front-mounting provision for add-on auxiliary contact blocks.
Contactors such as the ABB ASL12-30-01-81 provide electrically controlled switching for three-phase motors and other industrial power loads. Its three normally open main poles switch the power circuit, while the built-in normally closed auxiliary contact can support interlocking, status monitoring and control functions.
The ASL series uses low-consumption DC coils suitable for direct operation from compatible PLC outputs. Correct polarity must be observed at the A1+ and A2− coil terminals, helping ensure reliable operation within automated machinery and industrial control systems.
