Product Overview
- NYKC2 series AC contactor (hereafter referred to as contactor), mainly used for AC 50HZ or 60HZ, rated insulation voltage of 690V, rated working voltage is 380V under AC-3 use classification, in circuit with rated current to 800A, for long-distance making and breaking circuit, it also can work with proper thermal overload relay to form electromagnet starter, to protect circuits that may cause operation overload.
- The product satisfies GB4048.4, IEC60947-4-1 standard.
Structural Characteristics
- Cordwood installation methods can be used to install auxiliary contact group, air time-delay contact, thermal relay and other accessories, to form many kinds of derivatives (see sheet).
- AC contactor has such characteristics as small volume, light weight, small power consumption, long lifetime, safety and reliability;
- Contactor body has one pair of normal open or normal close auxiliary contacts under 32A and below, one pair of normal open and normal close auxiliary contacts under 40A and above, product body has no auxiliary contact under 115A and above, additionally;
- Except screw installation, Contactor also can use 35mm﹝NYKC2-09~95﹞, 75mm﹝NYKC2-40~95﹞ and 2×35mm﹝NYKC2-115~170﹞ for standard card rail installation.
