Overview

The ABB S201MR-K20 is a single-pole miniature circuit breaker (MCB) designed for overcurrent protection in North American electrical systems. Rated at 20A with a 10kA interrupting rating, this device meets UL 1077 standards for supplementary protectors, ensuring compliance with North American safety requirements. The K-characteristic trip curve provides optimized protection for inductive loads such as motors, transformers, and solenoids by allowing brief inrush currents while tripping quickly on sustained overloads or short circuits. This makes it ideal for applications where transient surges are common but sustained faults must be interrupted reliably. Equipped with ring cable lug terminals, the S201MR-K20 simplifies wiring by accommodating solid or stranded conductors securely. The ring lug design reduces connection resistance, minimizing thermal stress and ensuring long-term reliability in industrial, commercial, and infrastructure installations. Manufactured by ABB - Electrification, this MCB is part of the S200M series, a widely deployed range in panelboards, distribution boards, and control panels. Its compact 1-pole design allows space-efficient installation in tight enclosures while maintaining full compliance with UL 1077 for supplementary protection applications.
