The electronic compact starters of the HF...DOLE-24VDC series are hybrid starters for motors up to 3 kW / 400 V or resistive loads up to 9 A / 400 V in accordance with IEC/EN 60947-1, -4-2.
They include the direct start and overload protection functions with very wide current setting ranges as well as the safety functionality for emergency stop. Safety Integrity Level 3 according to the standard for functional safety IEC 61508-1 and Performance Level >e< according to ISO 13849-1 are certified. The devices also have ATEX approval.
The hybrid technology of semiconductors and bypass contacts makes HF starters particularly suitable for applications with frequent switching operations and are low-loss.
The compactness and integrated design of the devices save space, reduce wiring errors and save time during installation.
