The ABB WA4-13 is a mechanical latching unit designed to enhance the functionality of AF09 to AF96 contactors and NF contactor relays. This versatile component ensures that contactors remain engaged even in the event of a voltage drop or failure, providing reliability in various industrial applications. The WA4-13 features a robust mechanical latching mechanism that can be released either through an electromagnetic impulse, compatible with both AC and DC currents, or manually via a convenient pushbutton located on the unit's front face. This unit is easily mounted onto the front of a 1-stack contactor, occupying two central slots, while allowing for the addition of CA4 single pole auxiliary contacts on either side. The WA4-13 supports a wide range of control voltages from 100 to 250 V, making it a flexible choice for diverse control systems. Its compact design optimizes space and simplifies the conversion of standard contactors into latched contactors, enhancing operational efficiency and reducing the need for extensive inventory.
