IEC Combination Starters

Available21 products
IEC combination motor starters are made to standards designated by the International Electrotechnical Commission (IEC). Combination motor starters turn high-current circuits on and off and help protect downstream connections like motors, machinery, and electrical systems from damage caused by overheating, low voltage, and overcurrent. Combo starters are electrically operated motor controllers that combine contactors, overload relays, and short circuit protection in the form of circuit breakers or disconnect switches inside a protective enclosure. IEC combination starters are cost-effective alternatives to heavy-duty NEMA combination motor starters.

Circuit Breaker Starters with Thermal Overloads

Circuit Breaker Starters with Thermal Overloads

These IEC combination motor starters with thermal overloads have circuit breakers that trip if the connection experiences an electrical overload or short. They shut off power immediately if there is an electrical malfunction to protect high-current industrial equipment and operators. Breakers are manually reset after they trip to resume normal operation. Thermal overloads, also known as heaters, prompt motor starters to break electrical connections with downstream equipment once a set temperature is reached to protect connected loads from overheating and causing damage. They contain either bimetallic strips or melting alloy solder materials. When the current exceeds a predetermined threshold and temperatures rise, the material bends or liquefies, causing the thermal unit to break the circuit and cause the motor starter to break its power contacts. As the materials cool down, they will return to their normally closed position and the circuit can be reset automatically or manually.
