Chint 40A 1 Pole B Curve 6kA MCB

The CHINT EBG-1P-B40 is a compact and reliable Miniature Circuit Breaker (MCB) designed to provide essential protection for electrical circuits against overload and short-circuit faults. As part of CHINT’s EBG series, this device is widely used in modern electrical distribution systems where dependable circuit protection and compact installation are required.

Rated at 40A, the EBG-1P-B40 is a single-pole (1P) B-curve MCB, making it suitable for general-purpose applications with standard inrush current characteristics. It is commonly installed in residential consumer units, commercial distribution boards, and light industrial control panels, offering stable and fast fault interruption to protect wiring and connected equipment.

The device operates with a Type B tripping curve, meaning it will trip at approximately 3–5 times its rated current, making it ideal for resistive and low-inductive loads such as lighting circuits, socket outlets, and general power distribution. With a breaking capacity of 6kA, it is capable of safely interrupting fault currents in typical low-voltage installations, helping to prevent electrical damage and fire hazards.

Its compact modular design allows for easy installation on a standard DIN rail, ensuring compatibility with most modern distribution boards. The EBG series is also designed for cost-effectiveness while maintaining CHINT’s reputation for safety and reliability.
