Description: Model: R9F44463 Type: Miniature Circuit Breaker (MCB) Poles: 4 (Four-pole protection) Rated Current: 63 A Rated Voltage: 400 V AC Application: The R9F44463 is designed for overcurrent protection in four-phase systems, typically used in industrial, commercial, and residential electrical installations. It provides both overload and short-circuit protection to prevent damage to electrical circuits and connected devices. Mounting: DIN rail mounted Standards Compliance: IEC 60898-1, UL 489, CE marking Parameters: Rated Current (In): 63 A Number of Poles: 4 (for four-phase systems) Rated Voltage (Ue): 400 V AC (suitable for industrial and commercial power systems) Breaking Capacity (Icu): 10 kA (at 400 V AC) – The MCB can safely interrupt fault currents up to 10,000 A. Tripping Characteristics: Type C (typically trips between 5 to 10 times the rated current) – ideal for inductive loads such as motors, transformers, and other heavy-duty equipment. Rated Frequency: 50/60 Hz Mechanical Durability: 20,000 cycles Electrical Durability: 10,000 cycles Rated Insulation Voltage (Ui): 690 V Rated Impulse Withstand Voltage (Uimp): 6 kV Temperature Range: -5°C to +40°C Auxiliary Contacts: Optional auxiliary contacts (NO or NC) for signaling or remote control purposes Connection Type: Screw terminals Protection Type: Overload and short-circuit protection
