Description
Residual current device designed for installation under the P250 h3+ series molded case circuit breakers, it is a type A-HI digital device, suitable for the detection of unidirectional fault currents with reinforced immunity.
It offers variable sensitivity (from 30 mA up to 6000 mA) and adjustable intervention time, and is equipped with differential and mechanical test buttons.
It also features LED signaling, remote fault output and fault warning function.
Made in accordance with the CEI EN 60947-2 standard, it allows wiring on screw terminals for rigid (35–185 mm²) or flexible (35–150 mm²) conductors, with insulation voltages up to 500 V and impulse withstand up to 6 kV.
Guaranteed RoHS and REACH environmental compliance.
