Fuji Electric EW50RAGU-3P030 Earth Leakage Circuit Breaker

Fuji Electric EW50RAGU-3P030 Earth Leakage Circuit Breaker is a three-pole protection device designed to quickly interrupt current when residual (earth) leakage is detected in a three-phase electrical system, helping to prevent electric shock and minimize damage to connected equipment. The unit is rated for 30 A and 440 V, indicating the maximum current the breaker will permit under normal operation and the voltage range it is designed to protect, making it suitable for medium-scale three-phase installations. The model designation EW50RAGU-3P030 identifies the specific Fuji Electric product and configuration, with '3P' denoting three poles and '030' reflecting the 30 A rating; this helps ensure compatibility in compatible panels and distribution boards. Common applications include three-phase distribution panels, motor control centers, and industrial electrical systems where leakage protection is required to meet safety standards and reduce the risk of shock or equipment damage.
