The Eaton WR210030 Residual Current Circuit Breaker is a 100 A, 2-pole device with a 30 mA residual-current rating for 240 V systems. As a residual current device (RCD), it detects imbalance between live and neutral conductors and interrupts power to protect people from electric shock and to help prevent electrical fires. This Cutler-Hammer/Eaton WR model provides ground-fault protection for 240 V installations that require automatic disconnection when leakage is detected.
