## Long description

The Hager SBN390 circuit breaker is a compact, three-module protective device rated for 100 A with a maximum coil voltage of 440 V. With dimensions of 52.5 mm width, 68 mm depth and 83 mm height, it is designed to fit standard distribution boards and modular enclosures. The device interrupts current in case of overloads or short circuits and helps maintain continuity and safety of electrical installations in residential, commercial and light industrial environments.
Advantages
The circuit breaker combines a high current rating with a small footprint, allowing efficient use of panel space while delivering 100 A protection. Its construction supports reliable tripping performance for overload and short-circuit conditions, and the modular 3-module format simplifies installation and replacement in common DIN-rail systems. The rated coil voltage of up to 440 V ensures compatibility with a range of AC control circuits.
