Residual current device that delivers focused earth-leakage protection for domestic and light commercial circuits. Peace of mind for electricians and homeowners who need dependable tripping when faults occur, Hager CDA263U RCD. Does it suit modern consumer units and wiring practices?
⚡ At a Glance
- • Protection Type: A-Type detection for earth leakage across AC and pulsating DC currents
- • Best for: Domestic and light commercial consumer units needing sensitive earth-leakage detection
- • Not ideal for: Installations that require combined overcurrent protection and leakage protection in one device
A double-pole RCD designed for dependable earth-leakage sensing. Clips onto standard DIN rails in a double-module form factor.
Sensitive fault detection - with A-Type 30 mA trip sensitivity
A-Type electronics detect both alternating leakage and pulsating direct currents, and the unit is specified at 30 mA sensitivity. That sensitivity level targets human-safety faults while avoiding nuisance trips from minor leakage.
Early detection reduces shock risk and helps isolate faults quickly. Works well where mixed loads or equipment can produce DC leakage.
Full isolation of circuits - with double-pole switching
Double-pole switching interrupts both live and neutral conductors during a trip, ensuring circuit separation. The double-pole design is standard for RCDs used where full isolation is required.
Complete disconnection simplifies safe maintenance and reduces residual voltage on the circuit. Suitable where neutral isolation is part of safe working practice.
Quick install into consumer units - with clip-on DIN-rail mount and double module width
The unit clips onto standard DIN rails and occupies a double-module width, matching common consumer unit layouts. Mechanical design fits into existing rail-mounted switchgear rows.
Faster wiring and neat installation in modern distribution boards. Space planning is straightforward thanks to the double-module format.
