Suitable for
Residential electrical distribution boards
Commercial office lighting circuits
Protection of standard household appliances
General purpose branch circuit protection
This device may not be suitable for industrial applications requiring higher breaking capacities or specialized tripping curves, such as those needed for large motor starting currents. It is also not intended for use in environments with extreme moisture or corrosive atmospheres without appropriate protective enclosures.
Key specifications
Number of poles: 1
Rated current: 40A
Tripping characteristic: B-curve
Breaking capacity: 6kA
Mounting type: DIN rail
Installation should be performed by a qualified professional in accordance with local electrical regulations. The device is mounted onto a standard DIN rail within a distribution board. Ensure that the supply voltage is disconnected before beginning the installation. Once snapped onto the rail, connect the incoming supply wire to the top terminal and the outgoing load wire to the bottom terminal, ensuring all connections are tightened to the manufacturer's specified torque to prevent overheating.
What to consider before purchase
Verify that the 40A rating matches your circuit requirements
Ensure the B-curve characteristic is appropriate for your load type
Check available space in your distribution board
Confirm compatibility with existing DIN rail systems
For optimal safety and longevity, regularly inspect the circuit breaker for signs of heat damage or loose connections. Do not attempt to modify or repair the internal mechanism of the device.
