1 pole DC breaker

Choosing the right breaker comes down to three key criteria: the type of network (AC or DC), the rated current In, and the tripping curve suited to your load. In this selection, you’ll find Acti9 iC60N 1P breakers with In ranging from 6 A to 63 A and curve C for common loads. Some models offer breaking capacity up to 10 kA. For DIY users, choose versions from 6 A to 25 A for light circuits; for heavier circuits, opt for 40 A or 63 A to protect more demanding lines.

The tripping curve describes how the breaker reacts to overloads or short circuits. Curve C is commonly used for household loads with moderate inrush current, such as lighting and outlets. It provides a good balance between protection and avoiding nuisance tripping. For the models on this page, most show a C curve, making them effective for residential circuits and small, lightly loaded industrial installations—while keeping normal current flow without unexpected trips.

For a residential user or a small office, a 1P breaker from 6 A to 16 A with curve C is ideal for lighting and outlet circuits. If your installation needs more protection, a 25 A or 40 A model works for heavier circuits, and a 63 A model may be required for larger distribution sections. For example, Acti9 iC60N 1P variants in 16 A and 40 A cover these use cases, and 63 A options are available for higher loads.

Make sure the breaker is designed for single-pole use (1P) and is compatible with your electrical panel. Mounting is typically done on DIN rails, and the standard 18 mm width dimensions fit easily into available slots. Also confirm the amperage and breaking capacity are appropriate for your cables and the relevant local standard. Some models explicitly state compliance with EN/IEC 60898-1 for safety and interoperability.

Dimensions and weight vary by model, but a common reference shows an 18 mm width with approximate dimensions around 85 mm in height and 78.5 mm in depth. This allows compact installation in most domestic equipment. For instance, some datasheets list these precise measurements, making it easier to calculate available space in the panel and compare with other equivalent modules.

Focus on the rated current In (e.g., 6 A, 10 A, 16 A, 20 A, 25 A, 40 A, 63 A), the tripping curve (ideally C for common loads), the network type (AC/DC if specified), and the breaking capacity (6 kA or 10 kA depending on the model). Also check the number of poles (1P) and the manufacturer compatibility references to avoid any mismatch with your electrical panel.
