Description
ABB A145-30-11 is a three-phase block contactor from the ABB A Contactor family, configured with an AC control circuit and a main contact arrangement for industrial switching duties. The assembly is intended for integration into motor starters, power-control panels, and distribution equipment.
Its contactor design supports switching tasks associated with motor starting, circuit isolation, bypass operation, and power distribution. The separate auxiliary contact arrangement allows the device to participate in control, interlocking, and status-signalling circuits within a coordinated control system.
For replacement work, the control-coil variant, main-circuit rating, auxiliary-contact arrangement, terminal construction, and overload-relay coordination must be checked against the existing installation. Any alternative A145 configuration should be verified by its complete ABB order code before substitution.
Before replacing ABB A145-30-11, verify the complete control-coil variant and auxiliary-contact arrangement against the existing starter circuit. Do not substitute another A145 order code without confirming its full ABB configuration.

FAQS
The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
ABB A145-30-11 is a three-phase block contactor in the ABB A Contactor family.
Does ABB A145-30-11 include auxiliary contacts?
The listed configuration includes one normally open and one normally closed auxiliary contact.
What should be checked when matching ABB A145-30-11 to an existing panel?
Check the complete order code, control-coil variant, main-circuit rating, auxiliary contacts, terminals, and overload-relay arrangement.
How should ABB A145-30-11 be replaced?
Replacement should use the same complete ABB order code or a formally verified equivalent with matching electrical and mechanical characteristics.
Can another A145-30-11 voltage variant be used as a direct substitute?
Not automatically. ABB lists several A145-30-11 order codes with different control-voltage ranges, so the complete code must be matched.
What information should be included in an ABB A145-30-11 quotation request?
Include the complete model, ABB product ID 1SFL471001R8011, required quantity, control-voltage variant, application, and any auxiliary or overload-relay requirements.
