Description

The ADM490C is a 4-pole RCBO with a 40A C-curve characteristic and 6 kA breaking capacity. It provides 30mA Type A residual current protection for three-phase plus neutral circuits in demanding commercial or light industrial environments.
This 40A variant is appropriate for main distribution circuits or high-current three-phase loads. The C-curve enables the device to accommodate significant inrush currents without nuisance tripping, while Type A sensitivity monitors for AC and pulsating DC fault currents.
Housed in a 4-module DIN rail format, the ADM490C is IP20 rated and operates at 230/400V AC. It conforms to IEC 61009 and RoHS standards.
