Suitable for
Residential electrical distribution boards
Commercial office power circuits
Protection of lighting systems
Control circuits requiring low-amperage protection
This device may not be suitable for high-inrush current applications, such as large industrial motors or heavy-duty machinery, where a different tripping curve might be required. It is also not intended for use in environments with extreme moisture or corrosive atmospheres without appropriate protective enclosures.
Key specifications
Rated current: 4A
Number of poles: 1P
Tripping characteristic: C-curve
Breaking capacity: 6kA
Mounting type: DIN rail
Installation should be performed by a qualified electrician in accordance with local electrical regulations. The device is mounted by snapping it onto a standard 35mm DIN rail within a distribution enclosure. Ensure that the supply wires are correctly terminated into the terminals and tightened to the manufacturer's specified torque to prevent loose connections and overheating.
What to consider before purchase
Verify that the 4A rating matches the load requirements of your circuit.
Ensure the C-curve characteristic is appropriate for the specific equipment being protected.
Check the available space in your distribution board for a single-module device.
Confirm compatibility with existing DIN rail systems.
For optimal performance and safety, regularly inspect the circuit breaker for signs of physical damage or discoloration and ensure that all terminal connections remain tight during periodic maintenance checks.
