UL definition of a Manual Motor Controllers, see also Chapter: 7.6.1 Defining Manual Mo-
tor Controllers (NLRV).
UL definition of a Combination Motor Controllers, see also Chapter: 7.6.2 Defining Com-
bination Motor Controllers (NKJH).
Unwanted disturbances in a communication medium that tend to obscure the data con-
tent.
The voltage that is fed to the motor, usually 3-phase.
A device used to avoid overheating of the motor. Can be of electronic or thermal type.
The rated current is the current drawn by a fully loaded motor at its specified nominal
speed.
The power consumed by the motor which is used for the magnetization of the motor.
Root Mean Square: The RMS value of an AC supply is the steady DC equivalent, which
would convert electrical energy to thermal energy at the same rate in a given resistance.
Short Circuit Current Ratings, see also Chapter: 7.1.6 Selecting the right Short Circuit Cur-
rent Ratings (SCCR) level for your UL application
The tripping Class defines the starting time at a specific current before tripping occurs.
Different classes exist, for example 10, 20, 30 etc. where class 30 allows the longest start-
ing time.
Rated operation voltage, see also Chapter: 2.2.1 Rated operational voltage (Ue).
