•  Circuit breaker requirements:
When the hoist motor starts, it draws a lot of power. It is therefore important that the electric supply is equipped with a suitable circuit breaker. The circuit breaker must be able to withstand the large starting current. We recommend using circuit breaker with one of the following ratings:
–  16D
–  20C
The circuit breaker is labeled with the rated current in amperes, but excluding the unit symbol, A. Instead, the ampere figure is preceded by a letter, B, C, or D, which indicates the instantaneous tripping current. That is the minimum value of current that causes the circuit breaker to trip without intentional time delay. In general terms, the C type circuit breaker will withstand 10 times the rated current for a short period of time. The D type circuit breaker will withstand 20 times the rated current. For more information, see standard BS EN 60898.
