Circuit breaker Eti-Polam ETIMAT10 1P C 20A 10kA AC (MPN 002131717)

The Eti-Polam ETIMAT10 single-pole miniature circuit breaker with C tripping characteristic provides overcurrent and short-circuit protection for single-phase residential and light commercial installations. Rated for 20 A continuous current and a 10 kA AC breaking capacity, this DIN-rail mountable device is designed to fit standard distribution boards and to interrupt fault currents reliably while allowing for moderate inrush currents from motors or lighting loads.

Advantages

This single-pole breaker combines a clearly defined C characteristic with a compact form factor for easy installation on a standard DIN rail. It offers a 10 kA AC breaking capacity to handle common fault conditions in household and small commercial electrical systems. The device is suited to applications requiring selective protection and stable operation under moderate transient currents without nuisance trips.

Suitable for

• Protection of single-phase circuits in homes and apartments
• Distribution boards in small offices or light commercial premises
• Circuits with moderate inductive inrush such as small motors, pumps, or fluorescent/LED lighting
• Selective coordination in simple single-phase feeders

Key specifications

• Poles: single-pole (1P)
• Tripping characteristic: C curve (suitable for moderate inrush)
• Rated current: 20 A
• Breaking capacity: 10 kA AC
• Mounting: DIN-rail compatible
• Application: overload and short-circuit protection for single-phase circuits

How to use

Install the breaker on a standard DIN rail inside a distribution board following local electrical codes and safety regulations. Connect the incoming phase conductor to the breaker’s line terminal and the outgoing load conductor to the load terminal, ensuring secure torque on terminals. Use a compatible neutral and protective earth arrangement in the panel. Verify correct wiring and perform insulation and continuity tests before energising. After installation, switch the breaker to the ON position and monitor for proper operation; if the breaker trips under normal load, inspect the circuit for overloads, short circuits, or installation faults.

Usage recommendations

For coordinated protection, pair this breaker with upstream and downstream overcurrent devices selected to the same electrical system characteristics and follow local standards for selective protection. Avoid using the device in circuits where extremely high fault currents exceed its 10 kA breaking capacity or where a different tripping characteristic is required for sensitive electronic equipment.
