Questions about this product
- How do I choose the right current rating, and what does the C-type curve mean?
- This breaker comes in ratings from 3A up to 63A to match your specific circuit load. The C-type trip curve handles moderate inrush currents between 5 to 10 times the rated current. It is ideal for standard home lighting, outlets, and small appliances without causing nuisance trips.
- How do I mount this circuit breaker, and does it require a specific enclosure?
- You can easily snap this single-pole breaker onto any standard 35mm DIN rail. Since it has an IP20 protection rating, you need to install it inside a suitable electrical distribution board or enclosure. This keeps the terminals protected from accidental contact.
- What are the maximum voltage and short-circuit limits for this breaker?
- This MCB is rated for operational voltages of 230V to 400V AC at 50Hz or 60Hz. It has a short-circuit breaking capacity of 6 kA to safely interrupt fault currents. Do not use it on DC circuits, as it is strictly rated for AC protection.
