The Hager HHA040U is a three-pole moulded-case circuit breaker (MCCB) from the H3 X160 range, engineered to protect three-phase low-voltage distribution circuits at moderate current levels. Rated at 40A with a 25kA short circuit breaking capacity, it is ideal for commercial or industrial applications requiring dependable fault protection. The integrated thermal-magnetic trip unit delivers responsive protection against overloads and instantaneous short circuits, safeguarding downstream equipment and maintaining operational continuity. Designed for straightforward panel integration, the HHA040U enables clear organisation of distribution boards and is compatible with Hager structured assemblies, providing reliable isolation and control for three-phase circuits.
Commonly used in commercial and industrial distribution boards, motor control centres, and secondary distribution panels. Suitable for three-phase circuits requiring reliable fault interruption, protection against overloads, and controlled isolation for maintenance. Typical installations include small to medium industrial plants, commercial facilities, and sub-distribution circuits.
The Hager HHA040U offers a practical solution for three-phase protection when a compact MCCB with a 25 kA rating is required. Its thermal-magnetic trip unit ensures reliable operation under both sustained and instantaneous overload conditions, while the H3 X160 design provides consistent compatibility across Hager panels. Engineers and installers benefit from simple integration, reliable isolation, and clear fault protection for moderate current three-phase circuits.
