Protection can be provided against people, fire, earth current leakage, or protecting from incorrect mains or cables connections. Also cabling and mounting is eased using different types of housing, double cage terminals, or pass-through connections for current measurement. Setup is always easy and accurate with the front dials and DIP switches.• TRMS AC or DC voltage monitoring• Over + over or over + under or under + under• Separately adjustable delays, adjustable hysteresis• Programmable latch / inhibit function• 2 x 8 A SPDT relay output• Zero current transformer for DEA71 and DEB71• Suitable for 1-phase and 3-phase mains• Max.
