Overview

The ABB S203MUC-C63 is a 3-pole miniature circuit breaker (MCB) from the System pro M compact® series, engineered for both AC and DC applications. Rated at 63A with a C-curve trip characteristic, this device provides reliable overcurrent protection in industrial and commercial electrical systems. The S203MUC-C63 delivers a rated short-circuit breaking capacity of 10 kA at 253V AC, 400V AC, and 440V DC, ensuring robust fault protection. Its high interrupting rating of 10 kA at 500V DC and 6 kA at 480Y/277V AC meets stringent safety standards for demanding environments. Designed for seamless integration with the System pro M compact® ecosystem, this MCB supports flexible installation and maintenance workflows. It mounts directly onto a 35 mm DIN rail and accommodates terminal/cable sizes from 18–4 AWG, simplifying wiring and reducing downtime. The S203MUC-C63 operates reliably across an ambient temperature range of -40°C to 70°C, maintaining calibration at 25°C. With a mechanical service life of 20,000 operations, it ensures long-term durability in continuous-use applications. This MCB is compatible with a wide range of System pro M compact® accessories, including auxiliary contacts (e.g., S2C-H6RU, S2C-S6RU), shunt trips, lockout/tagout devices, and rotary operating mechanisms, enabling expanded functionality and remote monitoring. Ideal for panelboards, motor control centers, and distribution boards, the S203MUC-C63 is a versatile solution for protecting circuits in industrial machinery, renewable energy systems, and commercial buildings. Choose ABB for dependable electrical distribution components that meet global standards.
