The relay will not operate if the input voltage drops below 70 of the minimum input value because l1 and l2 are also used to provide power. Width of 17 5 mm to reduce space required in panels. Article number 1 2 article description tt22 a415 1s psr tt17 a415 1s psr pcs pkt. Connection data type of connection screw connection nominal current carrying capacity 24 a rated voltage capacity.

Functions monitoring of phase sequence phase failure and asymmetry with adjustable asymmetrie. Wiring example timing charts phase sequence and phase loss operation diagram note. Phase loss detection while the motor is operating. Phase loss cannot be detected on the load side because.

Please enter your question. If the control relay coil or contacts the phase failure relay contacts or the shunt trip coil does not have the same voltage rating as the motor control transformers may be interposed where needed.
