- For three-phase induction motors of up to 22 kW / 400 V.
- Built in heat dissipater and electro-mechanical bypass relay.
- Substitutes the conventional contactors with a greater operating life. One in direct start-up and three in star-delta start-up.
- Lower maintenance cost.
- No pressure surge when using pumps and compressors. Reduces hammering.
- Less current and voltage drop during start up. Allows for reduced power consumption.
- Mechanical dimensioning can be optimised.
- Simplified automation.
- Assembly, setting, installation, commissioning and maintenance are made easy by the compact design.
- Reduces start and stop torque, eliminating mechanical problems.
- Additional cooling is not necessary thanks to the bypass built-in relay.
- Substitutes the conventional contactors: one for direct start-up and three for star-delta start-up
