## Summary description

Eti-Polam KZS-2M is a combined residual-current and overcurrent breaker (RCCB + MCB) in 2-pole configuration with 25 A rated current, B characteristic tripping curve and 30 mA residual current sensitivity (type AC). It provides protection against earth leakage and short-circuit/overload in residential and light-commercial electrical circuits and is mounted on DIN rail.

## Long description

Eti-Polam KZS-2M 2P 25A B 0.03A type AC is a combined residual-current device and miniature circuit breaker (RCCB+MCB) in a two-pole DIN-rail housing. Designed for residential and light-commercial electrical installations, it provides earth-leakage protection with 30 mA sensitivity while also protecting against overloads and short circuits with a 25 A rated current and B-type tripping characteristic. The device fits standard distribution boards and integrates both leakage detection and overcurrent interruption in a single module to simplify wiring and save space.
Advantages
The combined design reduces the number of modules required in a consumer unit by integrating residual-current detection and overcurrent protection into one compact unit. With 30 mA sensitivity it addresses personal protection against electric shock from alternating current faults, while the B tripping curve ensures reliable service for circuits with moderate inrush currents such as lighting and general-purpose outlets. DIN-rail mounting enables straightforward installation and replacement in standard electrical panels.
Suitable for
Residential branch circuits for lighting and sockets
Small commercial or office electrical circuits with standard loads
Protection of circuits where personal leakage protection (30 mA) is required
Retrofits or compact distribution boards where space saving is important
Key specifications
Poles: 2-pole configuration for single-phase circuits
Rated current: 25 A
Tripping characteristic: B curve (suitable for general-purpose loads)
Residual current sensitivity: 0.03 A (30 mA), AC type (senses AC leakage)
Function: Combined residual-current protection and overcurrent protection (RCCB + MCB)
Mounting: DIN-rail compatible housing for distribution boards
How to use
Mount the device on a standard DIN rail inside the distribution board and connect the supply and load conductors according to local wiring rules and the circuit diagram. Ensure the device is installed in a circuit with a neutral conductor present, as the residual-current function measures imbalance between live and neutral. Verify correct polarity and tighten terminals to the manufacturer’s recommended torque. After installation, test the residual-current operation using the built-in test button or an external RCD tester to confirm trip at the prescribed sensitivity.
Usage recommendations
Use this combined RCCB+MCB unit for single-phase circuits where both earth leakage and overcurrent protection are required. Verify compatibility with the connected equipment’s inrush currents and interrupting capacity requirements. Regularly test the residual-current function (typically every 6–12 months) and follow local electrical codes for installation and maintenance.
