MOTOR CONTROL

Four checks before selecting the contactor.

Separate load duty, coil data and auxiliary wiring before ordering.
 
01

Match the motor duty

Confirm motor power, line voltage and AC-3 duty against the 75 kW at 400 V rating.

02

Confirm the control coil

Use the full order code or nameplate to identify the required coil voltage and frequency.

03

Check auxiliary contacts

Verify that one normally open and one normally closed auxiliary contact meet the control scheme.

04

Plan mounting and handling

Allow for the block-contactor footprint, terminals and approximately 3.5 kg reference mass.

APPLICATION PROFILE

Three-phase motor switching and industrial power-circuit control.

SELECTION BOUNDARY

The coil voltage is order-code dependent and is not determined by A145-30-11 alone.

Official reference: ABB official Motor Protection and Control catalog.
03
BUYER FAQ

Six A145 contactor questions before ordering.

Specifications and system fit first; lifecycle and ordering checks follow.
01

What is the AC-3 motor rating?

ABB lists 75 kW at 400 V for A145-30-11.

02

What is the AC-1 current?

03

Which auxiliary contacts are built in?

The -11 suffix corresponds to one NO and one NC auxiliary contact.

04

Does the model define the coil voltage?

No. Confirm the complete order code or coil nameplate before ordering.

05

Is there a direct replacement?

A replacement must match poles, duty, coil, auxiliary contacts and mechanical arrangement.

EXPERIENCE

Nearly 10 Years of Industry Experience

Our team members have an average of more than 10 years of industry experience. We have worked with customers worldwide, including those from India, Germany, Sweden, Italy, Russia, Venezuela, Israel, and many other countries. Throughout our careers, we have collectively completed over 3,000 orders and established long-term business relationships with customers across nearly 30 countries.

02
PRODUCT JUDGMENT

Professional Product Judgment

We can often identify a product’s manufacturer, series, configuration, and function from its model number or nameplate photo. We also understand how revisions, firmware, and specifications affect compatibility and whether an alternative model can be used safely.

IN PRACTICE:

An Indian customer urgently needed a discontinued control module after several suppliers reported no stock. We identified its exact revision and function from the nameplate, checked compatible alternatives, and contacted factory and warehouse channels to locate matching inventory. After installation, the customer confirmed that the module operated correctly and later asked us to source additional spare parts.

03
SERVICE

Sincere and Patient Service

Our team treats every inquiry sincerely and answers every question patiently. Even for complex requests, we verify and respond to each detail instead of providing a rushed or uncertain answer.

IN PRACTICE:

A German customer sent a mixed list of automation products and asked repeated questions about revisions, condition, photos, and delivery. Our team organized the requirements, checked every item, and replied point by point. The customer said our detailed communication made the purchasing decision easier and continued sending us new inquiries.
