Hager 40A Single Pole 6kA B Curve MCB

The CHINT MTN140 is a reliable Miniature Circuit Breaker (MCB) designed for protection of low-voltage electrical circuits against overload and short-circuit faults. It is widely used in residential, commercial, and light industrial installations, offering dependable circuit protection and safe electrical distribution.

Rated at 40A, the MTN140 features a single-pole (1P) configuration and a Type B tripping curve, making it suitable for general-purpose circuits with low inrush currents such as lighting and socket outlets. It ensures fast disconnection during fault conditions, helping to protect wiring, appliances, and downstream equipment.

The device has a 6kA short-circuit breaking capacity, allowing it to safely interrupt fault currents in standard low-voltage networks. It is designed to meet IEC 60898-1 standards, ensuring compliance with modern electrical installation requirements. The breaker is intended for DIN rail mounting, making installation quick and compatible with standard distribution boards.

The MTN140 is part of a modular protection range and is commonly used as a final circuit protection device in consumer units and distribution boards where reliability, compact size, and cost-effectiveness are important.
