## Summary description

Eti-Polam KZS-2M is a 2-pole residual-current overcurrent protection device combining RCD and MCB functions. Rated current 25 A with C-type tripping characteristic and 30 mA residual current sensitivity (AC type). Designed for protection against earth leakage and short-circuit/overload in single-phase installations and general electrical circuits.

## Long description

Eti-Polam KZS-2M 2P 25A C 30mA type AC is a combined residual-current device and miniature circuit breaker designed for single-phase installations and general electrical circuits. It integrates leakage current detection with overcurrent and short-circuit protection in a single 2-pole unit. The device has a rated current of 25 A, a C-type magnetic trip characteristic for handling moderate inrush currents, and a 30 mA residual current sensitivity of AC type for protection against earth leakage.
Advantages
This unit combines RCD and MCB functions in one compact module, reducing the number of components and simplifying distribution board layouts. The 2-pole design provides simultaneous disconnection of phase and neutral, improving safety in single-phase circuits. The C-type trip curve balances protection against overloads and immunity to harmless inrush currents from motors and transformers. The 30 mA AC sensitivity offers standard personal protection against indirect contact and earth leakage faults.
Suitable for
Protection of lighting and socket circuits in residential and small commercial installations
Supply lines for small appliances, power tools and motors with moderate start currents
Replacement or upgrade of separate RCD and MCB combinations in consumer units
Key specifications
Poles: 2-pole (simultaneous disconnection of phase and neutral)
Rated current: 25 A
Tripping characteristic: Type C (moderate magnetic tripping)
Residual current sensitivity: 30 mA, AC type (senses sinusoidal AC leakage)
Function: Combined residual-current device and miniature circuit breaker
Typical mounting: DIN-rail compatible for standard distribution boards
Application environment: Indoor electrical installations for single-phase circuits
How to use
Install the device in the distribution board on a standard DIN rail, ensuring correct orientation and secure terminal connections for phase and neutral conductors. Connect the load and supply conductors to the corresponding input and output terminals, and tighten terminals to the manufacturer's recommended torque. Test the residual-current function after installation using the built-in test button or a suitable RCD tester to confirm operation. Observe local electrical codes and switch off supply before performing installation or maintenance.
Usage recommendations
Use this 2-pole 25 A C 30 mA residual-current circuit breaker in circuits where combined earth-leakage and overcurrent protection is required. Avoid using AC-type RCDs where pulsating DC leakage is expected; in such applications consider devices specified for A-type leakage. Periodically test the device and follow recommended maintenance intervals to ensure reliable protection.
