Description
S800-SCL-SR is ABB’s innovative self-resetting current limiting module which considerably increases the short-circuit breaking capacity of downstream manual motor starters and high performance MCBs The S800-SCL-SR is a self-resetting short-circuit current-limiter. The major advantage of S800-SCL-SR is the ability for continuous group protection. The S800-SCL-SR protects all downstream devices up to 100kA. In case of a fault current in one of the motor circuits the resulting short-circuit current is limited and only the faulty branch is cut off. After the downstream device has tripped, the S800-SCL-SR contacts re-close automatically. All other downstream devices continue to operate without interruption.
