Star-Delta Switch: A Smarter Way to Start Three-Phase Motors

Starting a three-phase induction motor can place considerable stress on both the electrical network and the driven equipment. When a motor is connected directly to the supply, the starting current can reach 3 to 8 times its rated current. This can cause voltage drops, while the high starting torque can create undesirable mechanical shocks. One proven way to reduce these effects is star-delta starting.

Rated short-circuit breaking capacity

Rated short-circuit breaking capacity represents the highest value of short-circuit current that a circuit breaker or fuse is capable of interrupting. Each protective device is designed for a specific rated power and therefore for a specific rated (load) current

Compact Circuit Breakers – Understanding the Tripping Characteristics

Low-voltage circuit breakers are used to protect low-voltage installations, cable lines, and connected equipment against overloads and short circuits. On the market, we encounter two different types of compact circuit breakers: those with thermo-magnetic (electromechanical) trip units and those with electronic trip units.
