Thermomagnetic automatic breaker TM2 and TM3

 

 

 

 

 

Technical characteristics:
 
Model: TM2

 - Rated operating current range: from 0.1 up to 80А

 - Rated operating voltage: up to 690V АС, 50/60Hz

 - Insulating voltage: 690V

 - Impulse voltage withstand: 6 000V

 - Electrical wear resistance (number of cycles): ≥1000000

 - Mechanical wear resistance (number of cycles): ≥10000000

 - Ambient temperature: -10°÷60ºС

 - Maximum altitude: 2000m
 
Mounting: On a DIN rail in boards or in watertight box for ТМ2
 

Advantages:

 - Option for independent operation or as an element of an automation system

 - Option for operation at higher frequency

 - Option for adjustment of protection activating range 

 - High reliability of the current characteristics

 - Option for change/choice of the protection current (according to the rated operating current)

 - Automatic compensation of the ambinet temperature

 - Easy mounting and long life
 
 

Functions:

 - For switching off alternating current consumers at current overload

 - For switching off the electrical circuit to the consumer at input short circuit 

 - For protection of the motor at lack/lowering of the phase voltage (if there is under voltage release)

 - Used as a protective operating element against overload, overheat or short circuit in control panels of induction motors 
 
 

Applications:

 - Industry

 - Building construction
