Chint 25A B Curve RCBO 30mA 1 Pole + Neutral

The CHINT NB1L-B25 RCBO (25A) is a compact, high-reliability protective device designed to deliver comprehensive electrical safety by combining the functions of a Miniature Circuit Breaker (MCB) and a Residual Current Device (RCD) in a single unit. It is engineered for use in modern electrical distribution systems where both overcurrent protection and earth leakage protection are required to ensure maximum safety for people, equipment, and property.

Built to meet demanding safety standards, the NB1L-B25 is widely used in residential, commercial, and light industrial applications, offering dependable protection against electrical faults such as overloads, short circuits, and leakage currents. Its integrated design reduces panel space requirements while simplifying installation and maintenance, making it an efficient solution for today’s compact electrical boards.

With a 25A rated current and a Type B tripping curve, this RCBO is suitable for general-purpose circuits that experience low to moderate inrush currents, such as lighting systems, socket outlets, and small appliances. The device is designed for fast disconnection in the event of a fault, significantly reducing the risk of electric shock or fire hazards.
