ABB RC4-2/440 Surge Suppressor for AFC40-AFC96 Contactors, 250-440V AC, 50/60 Hz
ABB
$118.26
The RC4-2/440 is a robust RC type surge suppressor engineered to mitigate the maximum overvoltage peak value and limit high pre-damping voltage frequencies that occur in control circuits during contactor operation. When a contactor coil opens, it can generate high voltage surges of several kilovolts, potentially causing interference and damage to sensitive electronics within the installation. This surge suppressor is capable of operating within a control voltage range of 250 to 440 V AC at 50/60 Hz. Designed for seamless integration, the RC4-2/440 mounts directly onto AFC contactors, either on the top or bottom, and includes coil connection terminals. It is specifically tailored for use with AFC40 to AFC96 contactors, ensuring reliable protection and performance.
