Installatieautomaat Hager NBN316 3P, 16 A, 50–60 Hz, 52.3×70×83 mm

Hager NBN316 is a three-pole miniature circuit breaker designed for protection of three-phase electrical circuits. With a rated current of 16 A and compatibility with AC mains at 50–60 Hz, this device provides overcurrent protection in a compact form factor measuring 52.3 × 70 × 83 mm. Intended for installation in distribution boards, the breaker suits residential and light-commercial electrical systems where reliable short-circuit and overload protection is required.

Advantages

The breaker offers three-pole protection in a single compact module, allowing secure disconnection of all phases simultaneously. Its 16 A rating matches common branch circuit loads in homes and small businesses, and the 50–60 Hz compatibility ensures use with standard power systems. The compact dimensions save space inside distribution panels and simplify wiring layouts during installation.

How to use

Install the device in the distribution board according to local electrical regulations and manufacturer installation practices, ensuring correct identification of the three phases and secure terminal connections. Switch off the incoming supply before making connections. After mounting and wiring, test the breaker by applying normal operational loads and checking for correct tripping behaviour under fault conditions. Routine inspection and testing should be performed as part of periodic electrical maintenance.

Recommendations

Use this breaker as part of a coordinated protection scheme with compatible upstream and downstream devices. Verify cable ratings and load currents to ensure the 16 A rating is appropriate; avoid using the breaker where sustained currents exceed its nominal rating. Follow applicable standards and local codes for installation and periodic verification.
