Mounting: On a DIN rail in boards or in watertight box for ТМ2

– 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


– 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
