The usual way of preventing a small motor from drawing too much current is to install overcurrent protection in the form of a circuit breaker or some other kind of limiter. But installations that ...

In Part 1, we saw why we must separate overload protection from fault and short circuit protection for motor circuits. But correctly sizing these different devices can be confusing. And if you follow ...

Jams or sudden stops during an indexer's moving periods can subject its drivetrain to damaging torques. A few setups prevent damage in such situations. In engineering, indexing is the movement from an ...

When an overload device sized in accordance with 430.32(A)(1) and (B)(1) is not sufficient to start the motor, higher size sensing elements shall be permitted if the trip current does not exceed ____% ...

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 ...

The RSGD Series from Carlo Gavazzi is an easy to use soft-starter for 3-phase induction AC motors, needing just three settings. The self-learning algorithm adjusts the unit's parameters to work with ...
