Monitoring relays from Carlo Gavazzi can also be used as 1-phase or 3- phase over current monitoring relays when connected with MI or MP current transformers.Owing to the built-in latch function, the ON-position of the relay output can be maintained. The red LED indicates the alarm status. · · · AC/DC over voltage monitoring relay · · Adjustable voltage limit on relative scale · · Programmable latching at set level · · Output: 8 A SPDT relay normally de-energized · · 3-phase monitoring relays for phase sequence and phase loss · · Detect when all 3 phases are present and have the correct sequence · · Limiting temperature -40 to 125°C · · IP65 degree of protection · · Unsuitable for ModuPlug®
