This overview compares the ETI ETIMAT 10 Polam 25A B-Curve 2-pole miniature circuit breaker with similar protective devices from Eti-Polam, Hager, CNC, Schneider, and Spamel. All featured products are designed to protect electrical installations against overloads and short circuits, but they differ in pole count, rated current, tripping characteristic, and breaking capacity.
⚙️ The table below compares the core technical characteristics, such as pole count, rated current, tripping curve, breaking capacity, and their practical significance for electrical installations.
| Parameter | ETI ETIMAT 10 Polam 25A B | Eti-Polam ETIMAT10 10A B | Hager NCN110 10A C | CNC NV821617 25A C | Schneider IC60N 20A C | Spamel SPMN-C25/3 25A C | Practical significance |
|---|
| Pole count | 2-pole | 2-pole | 1-pole | 4-pole | 3-pole | 3-pole | Determines the type of electrical circuit supported (single-phase, two-phase, or three-phase). |
| Rated current | 25A | 10A | 10A | 25A | 20A | 25A | Indicates the maximum continuous operating current the device can carry without tripping. |
| Tripping curve | B | B | C | C | C | C | Type B is more sensitive to short-circuit faults for general circuits, while Type C allows higher inrush currents. |
| Breaking capacity | 10 kA | 10 kA | 10 kA | 6 kA | 10 kA | 6 kA | Represents the device's ability to safely interrupt high fault currents during a short circuit. |
◎ The table below evaluates the suitability of each device for various use cases and application scenarios across residential, commercial, or industrial electrical systems.
| Use case | Recommended product | Why |
|---|
| Protecting a two-phase line with standard loads (25A) | ETI ETIMAT 10 Polam 25A B-Curve | Provides precise protection with a B curve in a two-phase format rated for 25A operations. |
| Protecting a two-phase line with lower loads (10A) | Eti-Polam ETIMAT10 10A B | Features a similar two-phase build and B curve but is sized for lower current requirements. |
| Protecting a single-phase circuit with inductive or motor loads | Hager NCN110 10A C | Single-pole design with a C curve handles startup current spikes better in single-phase setups. |
| Protecting a three-phase industrial distribution line | Schneider IC60N 3-Pole 20A C | Three-pole format and 20A rating with a C curve suit balanced three-phase power distribution. |
| Protecting a four-phase power distribution network | CNC NV821617 4P 25A C | Four-pole configuration allows complete switching of all phases and neutral in complex panels. |
The ETI ETIMAT 10 Polam 25A B-Curve circuit breaker is best suited for two-phase electrical distributions requiring a 25A rating and sensitive B-curve short-circuit protection. Choose this model when you need a reliable two-pole modular device with a high breaking capacity for residential, commercial, or industrial distribution boards.
