The 'C' represents the tripping characteristic, indicating the breaker is designed to trip between 5 and 10 times the rated current, which is suitable for standard loads with surge potential.
No, this is a 1-pole (1P) breaker designed specifically for single-phase electrical circuits.
This model has a rated short-circuit breaking capacity of 6kA.
While it is a maintenance-free device, you should ensure that terminals remain tight and that the environment is kept dry and clean.
The unit has a width of 17.8 mm, which corresponds to 1 standard module width.
Identify if there is a short circuit in the downstream wiring or if a connected device is faulty. Disconnect all appliances and try resetting the breaker.
Check if the internal mechanism is damaged or if there is excessive load on the circuit exceeding 20A. If the issue persists, the unit may need replacement.
Installation must be performed by a certified electrician following regional electrical standards. The device clips directly onto a standard DIN-rail. Ensure all wire connections are tightened to the manufacturer's specified torque settings to prevent heat buildup and poor connectivity. As an IP20-rated device, it should be housed in a distribution board or protective enclosure to shield it from moisture and debris. Periodically inspect the terminals for signs of oxidation or loose wiring during routine maintenance of your electrical panel.
