The KZS 1M-FN is a residual current circuit breaker with integral overcurrent protection (RCBO), designed to be functionally dependent on line voltage. It is a single pole device that switches the phase pole while keeping the neutral pole fixed. The device operates at voltages above 85V and includes a sealing option.

The product dimensions are provided in a schematic, indicating a compact design suitable for various installations.

• The blue conductor, with a length of 600 mm, serves as the neutral conductor on the line side.
• The white conductor is connected to FE and is used for earthing the electronics.

The product is available in various rated currents (6A to 40A), each with specific code numbers for tripping characteristics B and C. The weight ranges from 177g to 192g, and packaging is typically 1 piece per box, with 42 boxes per package.
