product details

Type and meaning

Product structure characteristics

□It has simple, compact, new and unique, with modular function and assembly modularization.

□The coil is packaged in plastic, with advanced technology, beautiful appearance, good insulation strength and high mechanical strength.

□For ZHCt-120~780-1200-1400, coil and static iron core form a drawer for pushing in and puling out by pressing the button and thus for easy repair.

□The are extinguishing chamber is made of high-strength plastic, which has high mechanical strength and good are extinguishing performance and is fixed by locking bar rotating compression spring, which is convenient and reliable.

□There are many auxiliary contacts, which are replaced easily. For ZHCt-120~780~1200~1400 contactors, the coil is provided with a special auxiliary contact for DC control of self-locking conversion. It is allowed to additionally install two auxiliary contactor sets so that there are 8 pairs of auxiliary contactors. The auxiliary contactor sets are installed only alone the guide rail. with no need of screws. Give it a push,when you hear a click, the auxiliary contactor sets are installed successfully.If the air damping type time relay is required, it can be used directly to replace the auxiliary contact set.

□The contactor can save electricity significantly,ZHCt-400-780~1200-1400 features AC input and DC control.

□The mechanical interlocking of the contactor is simple and reliable. Two contactors can be interlocked horizontally. ZHCt-120 ~630contactors can also realize vertical interlocking of two contactors and vertical interlocking between three contactors.

Main parameters and technical performance

□Action performance:The pull-in voltage is 85%~110% Us the release voltage is 20%-75%Us for the AC coil.and 10%~75%Us for the DC coil.

□Coil control voltage:ZHCt-120~780~1400 AC 127.220,380V DC 110,220V,can also be used for coils of any other voltage.

□Recommended short circuit protection for contactors is NT series fuse.
