Type A indicates that the device can detect both AC and pulsating DC residual currents, which is necessary for modern electronics.
While it fits standard DIN rails, it is highly recommended to use it within Lewden consumer units to ensure proper busbar alignment and mechanical fit.
An MCB only protects against overcurrent (overload/short-circuit), whereas an RCBO adds an integrated RCD function to protect against earth leakage.
You should press the test button at least every six months to verify the mechanical trip functionality.
Yes, this device is designed for standard UK 230V AC residential single-phase supplies.
Check the circuit for existing neutral-to-earth faults or insulation resistance issues before resetting.
Ensure the device is powered correctly; if it still fails, the internal mechanism may be faulty and the unit must be replaced.
Verify if the connected appliance has excessive leakage current or a faulty component causing intermittent earth faults.
Installation must be performed by a certified electrical contractor to comply with BS 7671 regulations. The RCBO snaps onto standard DIN rail systems commonly found in modern consumer units. Ensure that all electrical supplies are isolated before attempting to mount or wire the device. Once installed, perform a standard RCD trip test using a multifunction tester to verify that the 30mA sensitivity functions correctly. Regularly check the device by pressing the 'Test' button every six months to ensure the mechanical tripping mechanism remains operational.
