ABB AFS12Z-30-22-30 3-Pole Contactor for Machine Safety Applications with 24V DC Coil and Built-in Surge Suppression

The ABB AFS12Z-30-22-30 Afs12Z is a robust 3-pole contactor designed specifically for machine safety applications. It features fixed front-mounted auxiliary contact blocks with 2 normally open (N.O) and 2 normally closed (N.C) contacts, ensuring reliable monitoring and control of circuits. The contactor is equipped with mechanically linked and mirror contacts, enhancing system safety by always guaranteeing the correct contactor status. The control circuit is optimized with an electronic coil interface, dedicated to 24 V DC for direct control by PLC-output with a minimum of 250 mA, and boasts low holding consumption of up to 1.7 W, significantly reducing panel energy consumption. The front-mounted auxiliary contact block is permanently fixed and protected by a cover to prevent manual operation, with a distinctive yellow housing for easy identification. It supports a minimum switching capacity of 12 V / 3 mA, with a failure rate of 10^-7 as per IEC 60947-5-4 standards, and includes built-in surge suppression for added reliability. This contactor is capable of controlling motors up to 5.5 kW at 400 V AC (AC-3) or 7-1/2 hp at 480 V UL, and can switch power circuits up to 28 A (AC-1) or 28 A UL general use. It is compliant with key safety standards EN ISO 13849 and EN 62061, ensuring the safe operation of machinery and equipment. The AF technology incorporated in the contactor allows for a wide control voltage range (100 ... 250 V), accommodating large voltage variations and ensuring consistent performance even in unstable networks. The compact design includes built-in surge protection and allows for easy integration with additional auxiliary contact blocks and a wide range of accessories, making it a versatile and efficient choice for machine safety applications.
