## Long description

Hager SBN340 is a Type B miniature circuit breaker with a rated current of 40 A intended for DIN‑rail distribution boards. It occupies 3 modules (52.5 mm width) and provides overcurrent protection by tripping on overloads and short circuits. With compact dimensions of 52.5×68×83 mm, this breaker is designed to fit into residential and light commercial electrical installations where selective protection and straightforward installation are required.
Advantages
The Type B tripping characteristic ensures reliable protection for circuits with primarily resistive loads and low inrush currents. Three-module width allows integration of the device in multi‑way consumer units while keeping the overall panel footprint small. The device is suitable for standard DIN‑rail mounting and complies with common installation practices, enabling easy replacement or upgrade of existing breakers without significant cabinet modification.
Suitable for
 Protection of lighting circuits in residential buildings
 Protection of socket circuits for household appliances
 Light commercial electrical circuits with mainly resistive loads
 DIN‑rail distribution boards in renovation and new‑build projects
Key specifications
 Type: B characteristic (suitable for resistive loads with low inrush)
 Rated current: 40 A
 Number of modules (width): 3 modules (52.5 mm)
 Mounting: standard DIN‑rail
 Function: protection against overload and short‑circuit
 Overall dimensions (W×H×D): 52.5×68×83 mm
How to use
Install the breaker on a standard DIN‑rail within the distribution board, ensuring the rail and enclosure meet local electrical codes. Connect the incoming supply to the line terminal and the outgoing circuit conductor to the load terminal, tightening terminals to the manufacturer’s recommended torque. Verify correct orientation and secure mounting. After wiring, switch the device to the ON position and test the circuit for proper operation. For safety, isolate power before installation and perform continuity and insulation checks as required.
Usage recommendations
Use this Type B, 40 A breaker where circuit loads are mainly resistive and inrush currents are low. For circuits with motors, compressors, or other high inrush devices, evaluate the need for a different tripping characteristic. Ensure terminal connections are tightened per installation guidelines and that the overall panel protection coordination is reviewed by a qualified electrician.
