Description

The CDA463U is a 4-pole RCCB rated at 63A with 30mA Type A residual current sensitivity. It provides earth leakage protection across all three phases and neutral in three-phase installations such as commercial buildings, light industrial premises, or sub-distribution boards.
The 63A rating and 4-pole configuration make the CDA463U suitable as a main or sub-main protective device in three-phase distribution boards. Type A sensitivity ensures reliable detection of AC and pulsating DC residual currents from inverter-controlled and electronic equipment.
The device is DIN rail mountable and operates at 230/400V AC. It is IP20 rated and RoHS compliant, with packaging of 1 piece per unit.
