TAR-463L Automatic Recloser RCCB

Reclosing Mechanism Technology: The TAR-463L employs an advanced automatic reclosing (REC) mechanism that operates on 220/240V AC at 50Hz. The recloser activates within 0.4 to 1.0 seconds following an RCCB trip event, initiating the first reconnection attempt after a 10-second delay. If the fault persists and causes subsequent tripping, the system progressively extends the delay period through six stages, allowing increasing time for temporary faults to clear naturally.

RCCB Protection Characteristics: The integrated electromechanical RCCB provides Type AC earth leakage protection with a rated residual current of 300mA (0.3A). The device is designed with a non-trip threshold of 0.5 × I∆n, ensuring stability against minor leakage currents while maintaining sensitivity to genuine fault conditions. With a rated breaking capacity of 500A and rated limited short-circuit current capacity of 6kA, the TAR-463L offers comprehensive protection against both earth leakage and overcurrent conditions.

Control and Monitoring: The device features toggle-type control and includes auxiliary contacts (1 NO + 1 NC) rated for 250V / 2A, enabling integration with building management systems, remote monitoring equipment, or alarm circuits. The dry contact configuration ensures electrical isolation between the main circuit and control systems.

Lockout and Reset Logic: After six unsuccessful reclosing attempts, the TAR-463L enters a lockout state, requiring manual reset to restart operation. This intelligent safety feature prevents continuous reclosing in the presence of persistent faults, ensuring personnel safety and preventing equipment damage.

Environmental Durability: Designed for demanding applications, the TAR-463L operates reliably across temperatures from -35°C to +70°C and humidity levels up to 93%. The device is rated for 5,000 electrical cycles, ensuring long-term reliability in high-utilization installations.
