FuseBox RTA062030B 30mA Curve B 20A Type A RCBO
FuseBox RTA062030B 30mA Curve B 20A Type A RCBO is designed for medium-load domestic circuits where combined overcurrent and earth fault protection is required. It is commonly used for radial socket circuits, electric underfloor heating supplies and selected dedicated appliance circuits when specified by the circuit design.
This 20A device combines overload protection, short-circuit protection and 30mA residual current protection in one compact unit. The Curve B tripping characteristic is suitable for standard domestic loads, while Type A protection detects AC and pulsating DC residual fault currents.
