The HNT251JR from Hager is a compact circuit breaker designed according to DIN EN 60947-2 to protect electrical installations and networks from overload and short circuits. With a rated current of 250 Amperes and a short-circuit strength of 40 kA, this breaker offers a reliable solution for demanding applications. The trip curve of the electronic release can be precisely adjusted via a rotary switch, allowing for customization to specific requirements. The breaker features multiple adjustable trip settings that ensure a differentiated response to overload and short-circuit conditions. A series of LEDs provide visual feedback on the operating status and potential faults, facilitating monitoring and maintenance. The HNT251JR is thus a robust and versatile choice for the protection of electrical systems.

• Adjustable trip curves for overload and short-circuit current
• Activatable I²t function for trip curve adjustment
• Visual status indicators via multiple LEDs
• Differentiated setting of neutral conductor protection
• Robust design for demanding applications.
