Circuit breaker Eti-Polam ETIMAT 6 1P B20 6 kA - miniature overcurrent protection

The Eti-Polam ETIMAT 6 1P B20 miniature circuit breaker is a single-pole overcurrent protection device intended for residential and light commercial electrical installations. It features a B20 tripping characteristic, a thermal-magnetic trip unit and a rated breaking capacity of 6 kA. The breaker is designed for DIN-rail mounting in standard distribution boards and provides reliable protection for circuits up to 20 A against overloads and short circuits.

Advantages

The ETIMAT 6 1P B20 combines a compact housing with a thermal-magnetic mechanism that ensures automatic disconnection under both sustained overload and instantaneous short-circuit conditions. Its B-type characteristic gives fast response to low inrush currents typical for lighting and general-purpose circuits while avoiding nuisance trips from moderate startup currents. The device’s 6 kA breaking capacity supports coordination with common upstream protection and offers robust interruption performance for typical residential networks.

Suitable for

• Protection of lighting circuits in homes and apartments
• Overcurrent protection for socket and general-purpose branch circuits
• Integration into DIN-rail distribution boards and consumer units
• Use in light commercial installations with standard load profiles

Key specifications

• Pole configuration: single-pole
• Tripping characteristic: B20 (thermal-magnetic)
• Rated current: 20 A
• Breaking capacity: 6 kA (rated short-circuit making and breaking capability)
• Mounting: DIN-rail compatible
• Application: overcurrent and short-circuit protection for branch circuits

How to use

Install the breaker on a standard DIN-rail inside the distribution board, ensuring power is isolated before making connections. Connect the supply conductor to the line terminal and the load conductor to the load terminal, observing proper torque and conductor sizes per local wiring regulations. After wiring, switch the device ON to restore the circuit. In case of trip, first isolate the faulted circuit and clear the cause of overload or short circuit before resetting the breaker.

Usage recommendations

For safe and reliable operation, select this B20 breaker for circuits with predominantly resistive or low-inrush loads such as lighting and general outlets. Verify compatibility with upstream protective devices and ensure wiring and terminal torques comply with applicable electrical standards. For circuits with motors or heavy inductive loads, consider a breaker with a different tripping characteristic to prevent unwanted trips.
