Choosing a soft starter for a 40HP three-phase motor quickly comes down to three questions: Will the unit handle your supply voltage? Does the current rating match the motor? And can it physically fit your panel? The Kimatek ASAC-0/030/5/1 addresses those points directly with a 60A rating, a 200-575V input window, and dual mounting options.
Quick verdict
For a 40HP motor at 400V, this Kimatek soft starter delivers a 60A current rating and supports 45-66Hz operation. The auxiliary contact is built in, so you can wire status feedback without adding a separate block. The unit is cULus Listed with CE and IEC 60947-4 references, which matters if your project requires those compliance marks.
Who it suits
This unit fits a three-phase motor control install where the supply falls between 200V and 575V and the motor draws up to 60A. The DIN rail or chassis mount flexibility is a real advantage if you are working inside a compact enclosure. It is also a reasonable match for a 40HP/400V motor based on the title's rated load.
What stands out
The auxiliary contact is the feature that saves you from sourcing an extra component. The dimensions are 4" wide by 8" high by 7.375" deep, giving you a concrete envelope for layout planning. Withstand current is 5000A at 600Vac, which tells you the unit is built to handle a strong fault current without needing a separate current-limiting device for that rating.
Meaningful trade-offs
The price is USD 575.00, and that buys one unit rather than a full starter assembly. Because the input frequency range is 45-66Hz, motors running outside that span would not be a fit. Your circuit design will determine whether a separate bypass contactor is needed.
Bottom line
If you need a soft starter for a 40HP, 60A three-phase motor and want input voltage coverage from 200V to 575V, the Kimatek ASAC-0/030/5/1 is a strong candidate. The included auxiliary contact and dual mounting options make it easy to work into many control panels, and the listed price is straightforward for a dedicated motor control component.
3ph 40HP Motor Soft Starter 60A 200-575V 45-66Hz w/ aux contact ASAC-0/030/5/1
This Kimatek soft starter is rated for 40HP at 400V and 60A, with an input voltage range of 200-575V and a 45-66Hz frequency window. The auxiliary contact is already on the unit, which saves you from buying a separate block. The single-unit format means the price covers the soft starter only; any additional control or protection devices are separate. At USD 575.00, it's a direct match for projects that need these exact electrical specs.
