Description: Model: C9GQ 4P40A Type: Molded Case Circuit Breaker (MCCB) Poles: 4 (Four-pole protection) Rated Current: 40 A Rated Voltage: 400 V AC Application: The C9GQ 4P40A is used for overcurrent protection and is ideal for motor protection, power distribution systems, and industrial equipment. It is widely used in three-phase systems, providing reliable protection against overload and short circuits. The four-pole configuration makes it suitable for four-wire systems. Mounting: DIN rail mounted or panel mounted Standards Compliance: IEC 60947-2, UL 489, CSA C22.2, CE marking Parameters: Rated Current (In): 40 A Number of Poles: 4 (for four-wire systems, including neutral protection) Rated Voltage (Ue): 400 V AC (suitable for industrial and commercial power systems) Breaking Capacity (Icu): 25 kA (at 400 V AC) – Can safely interrupt fault currents up to 25,000 A. Tripping Characteristics: Adjustable thermal-magnetic tripping characteristics for overload protection and short-circuit protection. Thermal Protection: Adjustable to prevent damage from prolonged overloads. Magnetic Protection: Provides fast disconnection during short-circuit conditions. 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): 8 kV Temperature Range: -5°C to +40°C
