Residual current circuit breaker (RCBO) диф.NBH8LE40 1PN C25 30ma 4.5KA AC CHINT

Residual current circuit breaker CHINT NBH8LE-40 1P+N C25 30mA 4.5kA AC The CHINT residual current circuit breaker (RCBO) of the NBH8LE series is a combined device that unites the functions of a circuit breaker and a residual current device (RCD). This compact device takes up only two modules on a DIN rail and provides comprehensive protection: against overloads, short circuits and earth leakage currents. The C25 model with a 30mA setting is the standard for protecting domestic and office circuits where human safety must be ensured in the event of indirect contact with live parts. Technical parameters Manufacturer: CHINT Electric Series: NBH8LE-40 Rated current (In): 25 A Number of poles: 1P+N (phase and neutral) Tripping characteristic: C (5-10 In) Leakage current (residual current): 30 mA (0.03 A) Leakage sensitivity type: AC (sinusoidal alternating current) Breaking capacity: 4.5 kA Rated voltage: 230 V AC Device width: 36 mm (2 modules) Design features The device is fitted with a TEST (T) button intended for regular checking of the residual current protection module. Pressing it simulates a leakage current, and a healthy device must break the circuit instantly. The mechanism of the device is designed so that the phase and neutral conductors open simultaneously, which raises the level of electrical safety. The design of the NBH8LE series is distinguished by highly stable operation of the electronic leakage protection components even when the mains voltage fluctuates. Advantages Space saving: Combining two functions (circuit breaker + RCD) in one housing saves space in the distribution board. Comprehensive safety: Protection of the cable against ignition under overload and protection of people against electric shock when insulation is damaged. Ease of installation: Standard DIN-rail mounting and clear terminal marking speed up board assembly. Trip indication: A special flag or the position of the handle makes it possible to quickly determine the cause of the circuit disconnection. Reliable terminals: The clamp design ensures tight contact, preventing overheating at the point where conductors are connected. Scope of application The NBH8LE C25 30mA is widely used in flat and office distribution boards to protect socket-outlet groups to which medium-power household appliances (washing machines, dishwashers, air conditioners) are connected. The 30mA setting is recognised as the international standard for ensuring the electrical safety of people in residential and public premises.
