Product Overview
The Chint NL1-63 2P 40A 30mA RCCB is designed to provide life-saving residual current protection against electric shock and earth leakage in residential, commercial, and light industrial electrical systems. This 2-pole RCCB disconnects both the line and neutral conductors, offering full protection for single-phase circuits.
With a sensitivity of 30mA, this RCCB is ideal for personal protection, while the AC-type sensing ensures it detects standard alternating leakage currents. Its 6kA short-circuit withstand capability makes it robust enough for use in modern distribution boards.
