Live Electrical RKN320B-030 Bi-Directional RCBO
The Live Electrical RKN320B-030 Bi-Directional RCBO provides combined residual current and overcurrent protection for 400/415V AC three-phase circuits. This 20A, 3P+N device uses a Type A 30mA residual current element and is rated at 10kA breaking capacity. Featuring a Curve B trip characteristic (3–5 × rated current), this 20A device is suited to appropriately designed circuits where a lower magnetic trip threshold is required.
