TeSys D contactors have been designed for perfect integration into control systems. They can be used to create motor starters for almost any type of application. TeSys D contactors are available in 13 contactor ratings for inductive motor applications up to 150 full-load amps and resistive loads up to 200 amps. This 4 pole IEC contactor can be mounted on DIN rail or mounted directly to a panel. Contactor has two normally open and two normally closed power contacts. Power contacts have a 25A resistive load rating. Contactor is supplied with a 48 VAC 50/60 Hz coil. Contactor has one normally open and one normally closed auxiliary contact built-in as standard. The NC contact is mirror certified. Screw clamp terminals are used for load and auxiliary connections. An extensive line of accessories makes it easy to meet the requirements of most applications. The contactor is 3.35 inches tall, 1.77 inches wide and 3.62 inches deep. It weighs 0.80 lbs. Contactor is certified to UL, CSA, IEC, CCC, EAC and Marine standards. Contactor also meets the requirements of RoHS/REACh making it a Green Premium product.
