## Summary description

Two-pole residual-current circuit breaker (RCCB) Kanlux KRD10-2/40/30-AC provides 40 A rated current and 30 mA residual current sensitivity (type AC). Designed to detect AC residual currents and disconnect supply to protect against electric shock and leakage faults. Suitable for residential and light commercial installations to enhance electrical safety in circuits requiring RCD protection.

## Long description

The Residual-current circuit breaker (RCCB) 2P 40A 30mA Type AC Kanlux KRD10-2/40/30-AC is a two-pole device designed to monitor and interrupt AC residual currents in low-voltage electrical installations. It provides a rated current of 40 A and a residual current sensitivity of 30 mA (type AC), disconnecting the supply when an imbalance between live and neutral conductors is detected. The unit is intended for installation in distribution boards to improve protection against electric shock and to reduce the risk of fire caused by earth leakage faults.
Advantages
This RCCB offers reliable detection of alternating residual currents with quick disconnection behavior at a 30 mA threshold, helping to protect people from direct contact with live parts. The two-pole design enables simultaneous isolation of both live and neutral conductors, and the compact form factor facilitates mounting in standard DIN-rail distribution panels. Designed for residential and light commercial use, the device is compatible with typical circuit wiring and contributes to meeting safety requirements in modern installations.
Suitable for
Protection of household circuits such as lighting and socket groups
Supplementary protection in small commercial premises and offices
Use in distribution boards for earth leakage protection
Circuits requiring 40 A nominal current and 30 mA residual sensitivity
Key specifications
Poles: 2P (two-pole)
Rated current: 40 A
Residual current sensitivity: 30 mA (Type AC)
Rated operational voltage: suitable for standard low-voltage AC distribution (single-phase)
Tripping characteristic: detects alternating sinusoidal residual currents
Mounting: DIN-rail compatible enclosure for distribution boards
Application area: residential and light commercial electrical circuits
How to use
Install the two-pole RCCB in the distribution board on a standard DIN rail in accordance with local electrical codes and the manufacturer's installation instructions. Connect the incoming live and neutral conductors to the line terminals and the load conductors to the corresponding load terminals, ensuring proper tightening of terminals and correct polarity. After installation, test the device using the built-in test button, if present, to verify correct operation and tripping at the rated residual current. Coordinate the RCCB with upstream and downstream protective devices to maintain selectivity where required.
Usage recommendations
Use this RCCB for circuits where human protection against electric shock is required and where detection of AC-type residual currents is sufficient. Regularly test the device (typically once a month) using the test function and inspect connections periodically. When installing in systems with electronic loads or equipment that may produce DC components or complex fault currents, assess whether a Type A or other RCCB type is more appropriate.
