DC motor reversing contactor series TLD
The motor reversing contactor type TDL18A consists of 2 single pole contacts with 1NO/1NC each and the contactor TDL18B consists of 2 single pole contacts with 1NO each, both with internal wiring. The result is this compact product with a protection degree of IP 50. The normal operating mode is 50% interval mode. The maximum continuous load is 15min. The NC contacts are not designed to switch the current on or off.
The contactors have a very fast switch-off time (10msec.) and a relatively long pick-up time (about 20msec.).
This mode of operation enables safe reversals and prevents the contacts from being closed at the same time.
The use of spark quenching diodes increases the switch-off time and therefore it is very important to choose the correct type of diodes (diode+resistor).
The performance data can be taken from the TL11 model.
