Description: Model: A9F18250 Type: Miniature Circuit Breaker (MCB) Poles: 2P (Two-pole, for single-phase or two-phase systems) Rated Current: 50 A Rated Voltage: 230/400 V AC Application: The A9F18250 MCB is designed to provide overload protection and short-circuit protection for single-phase or two-phase electrical circuits, making it suitable for use in distribution boards, lighting circuits, appliances, and other low-voltage systems. This MCB is commonly used in residential, commercial, and industrial environments to ensure electrical safety and protect circuits from overcurrent conditions. Mounting: DIN rail mounted Standards Compliance: IEC 60898-1, UL 489, CE marking Parameters: Rated Current (In): 50 A Number of Poles: 2P (Two-pole for single-phase or two-phase systems) Rated Voltage (Ue): 230/400 V AC Suitable for single-phase and two-phase systems. Rated Breaking Capacity (Icn): 6 kA (at 230 V AC) – The MCB can interrupt fault currents up to 6,000 A. Tripping Characteristics: Type C (Instantaneous tripping for short-circuits and moderate delay for overload) Overload Protection: Trips between 5 to 10 times the rated current (for overload conditions). Short-circuit Protection: Instantaneous trip for short-circuit conditions. Frequency Range: 50/60 Hz Temperature Range: -5°C to +40°C Mounting Method: DIN rail mounted Connection Type: Screw terminals for secure and reliable wiring Mechanical Durability: 20,000 operations Electrical Durability: 10,000 operations Rated Insulation Voltage (Ui): 500 V Rated Impulse Withstand Voltage (Uimp): 4 kV
