TMS7 SERIES 

The TMS7 is designed to operate with or without a line 
contactor. In many regions there is a statutory requirement that 

a line contactor be employed with electronic motor control 
equipment. From a safety point of view, this is the preferable 
option, however is not necessary for starter operation. An 

additional benefit gained by use of a line contactor is isolation of 
the starter SCR’s in the off state, when they are most 

susceptible to damage from voltage transients. 
 

The TMS7 can directly control a line contactor via the Main 
Contactor Control output. 

 
As an alternative to a line contactor, either a circuit breaker with 

a no volt release coil operated by the TMS7 trip output, or a 
motor operated circuit breaker can be considered. If a motor 

operated circuit breaker is used as a line contactor, the potential 
delay between the breaker being told to close and phase power 
being applied to the TMS7 could cause the TMS7 to trip on 

installation faults. Closing the motorized breaker directly and 
using the breaker’s auxiliary contacts, or preferably a slave relay 

with gold flash contacts, to control the TMS7 can avoid this. 
 

Line contactors must be selected such that their AC3 rating is 
equal to or greater than the full load current rating of the 

connected motor.
