The WRT350C-030 is a 3-pole Type A RCBO designed for higher-current three-phase circuits requiring combined residual current and overcurrent protection. Rated at 50A with a C curve tripping characteristic and 30mA sensitivity, it provides dependable protection against overload, short-circuit, and earth leakage faults in a compact 3-module DIN rail format.

Type A residual current protection allows detection of AC residual currents and pulsating DC components, making this RCBO suitable for modern installations with electronic equipment and inverter-driven loads. The C curve response supports moderate inrush currents, commonly associated with motors, plant equipment, HVAC systems, and higher-load commercial distribution boards.

Installer note: The switched neutral design disconnects L1, L2, L3, and N simultaneously, improving isolation safety and reducing time required for insulation resistance testing.
