Compare MCB and ELCB.
MCB ELCB MCB stands for Miniature Circuit Breaker. ELCB stands for Earth Leakage Circuit Breaker. It protects against overcurrent. It protects against earth leakage currents It uses thermal and magnetic mechanisms to detect overcurrent. It detects imbalance between live and neutral currents. It is less sensitive to current changes. It is highly sensitive to current
