Figure 1. Restructuring the circuit in Figure 2 with redundant machinery power contactors and a double-pole interlock switch increases the probability that the circuit will work, even if a single ...

Electric drives require effective protection against overloads and short circuits. Both phenomena cause motor disruption and create a risk of damage to the motor. This could lead to a potentially ...

Altech’s load-safe LSF Series and RT Series non-fusible motor disconnect switches and accessories de-energize electrical circuits for safe maintenance, repairs, inspections and emergencies. RS has ...

Controlling a small dc motor without speed control sounds like a trivial task; a switch or a relay should suffice. However, several problems accompany this approach. For one, the switch, because of ...

Santa Barbara, Calif. — GIGAVAC has rolled out a sealed 150-amp single pole/single throw (SPST) normally open (NO) contactor that can power switch both AC and DC up to 750 volts. The GX11 sealed ...
