Product Description:

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 the neutral pole remains fixed. The device operates at voltages above 85V and includes a sealing option.

Dimensions and Connection:

The product dimensions are specified in the document, with a blue conductor of 600 mm length serving as the neutral conductor on the line side, and a white conductor connected to FE for earthing the electronics.

Packaging and Codes:

• Available in various rated currents (6A to 40A) with specific code numbers for tripping characteristics B and C.
• Each unit weighs between 177g and 192g and is packaged in quantities of 1/42.
