It works by detecting leakage current and immediately disconnecting the power supply when an imbalance occurs.<\/p>\n\n\n\n<p>In modern electrical systems, an <strong>RCCB breaker<\/strong> is essential for ensuring safety in homes, commercial buildings, and industrial environments.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-how-an-rccb-breaker-works\"><strong>How an RCCB breaker works<\/strong><\/h2>\n\n\n\n<p>An <strong>RCCB breaker<\/strong> continuously monitors the current flowing through live and neutral wires.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-leakage-current-detection\"><strong>Leakage current detection<\/strong><\/h3>\n\n\n\n<p>Under normal conditions, current flowing in the live and neutral wires is equal.

id=\"h-instant-circuit-disconnection\"><strong>Instant circuit disconnection<\/strong><\/h3>\n\n\n\n<p>Once detected, the device trips within milliseconds, cutting off electricity and preventing
