A 30 mA rating for an Earth Leakage Miniature Circuit Breaker (ELMCB) indicates the device's sensitivity to earth leakage currents, which is crucial for protecting against electrical shock and fire hazards. This means that the ELMCB will trip and disconnect the circuit if it detects a leakage current of 30 milliamperes (mA) or more. Such a rating is typically used in residential and commercial applications to enhance safety by minimizing the risk of electric shocks.
