Key Features Circuit Breaker Type: Fixed molded case circuit breaker with thermomagnetic protection. Poles: 3 poles for three‑phase circuit protection. Trip Mechanism: Thermal‑magnetic (TMF) — provides overload and short‑circuit protection. Front Terminals: Designed for easy front access connections for incoming and outgoing conductors. Compact Design: Slim profile suited for modular panel installations. Electrical Ratings Rated Current (In): 63 A — continuous current capacity of the main circuit. Rated Uninterrupted Current (Iu): 125 A — maximum continuous conductor rating of the breaker frame size. Rated Operational Voltage: 550 V AC for AC power distribution. 250 V DC for DC systems. Insulation Voltage (Ui): 690 V — withstands common low‑voltage system insulation requirements. Impulse Withstand Voltage (Uimp): 6 kV — resistance to high voltage transients. Service Short‑Circuit Breaking Capacity (Ics): Varies by voltage, typically several kiloamperes in AC systems. Ultimate Short‑Circuit Breaking Capacity (Icu): Higher fault‑current interruption capability rated by voltage system. Rated Frequency: Suitable for 50 Hz / 60 Hz systems. Mechanical & Performance Durability: Electrical Life: Rated for thousands of operations under load. Mechanical Life: Designed for repeated operation cycles. Performance Level: Suitable for general power distribution and protection. Operating Environment: Typical industrial ambient conditions inside enclosed panels. Physical & Installation Mounting: Panel or enclosure mounted. Terminals: Screw/clamp front terminals for secure conductor connections. Frame Size: Compact MCCB frame for space‑efficient distribution boards. Weight & Footprint: Moderate weight and size suitable for standard low‑voltage switchgear. Typical Applications Low‑voltage distribution boards in industrial and commercial buildings. Branch circuit protection for feeder circuits and motor loads. Control panels and machinery power isolation where reliable overcurrent protection is needed. General electrical safety against overloads and short circuits.
