CHINT 169347 ā NM8L 350A 4P RCCB
350A rated, 4-pole residual current MCCB with 50kA breaking capacity and 100% Ics. Built on the NM8L-250 frame using a 250A module, equipped with X2-type earth leakage protection (0.1 / 0.3 / 0.5 / 1A), thermal-magnetic adjustable trip unit, and programmable T1 time delay.
š¹ Description (English):
The CHINT 169347 ā NM8L-250S/250/4 X2 T1 is a high-reliability molded case RCCB ideal for industrial systems requiring sensitive earth leakage protection and robust fault interruption. With a 350A current rating and 50kA breaking capacity at 100% Ics, it integrates X2 residual current sensing, allowing wide leakage trip thresholds, a configurable T1 time delay, and an adjustable thermal-magnetic trip unit for overload and short-circuit protection. The breaker is housed in an NM8L-250 frame with a 250A internal module for optimal thermal handling.
