Current Monitor Relays

Current Monitor Relays from Macromatic

Macromatic Products Menu :

Current Monitor Relays monitor AC single phase currents for over or under current conditions. A separate 24 or 120VAC input (supply) voltage is required to power these units. Three current ranges are available: 0.1 1A; 0.5 5A; and 1 10A. An external current transformer may be used to extend the range of these products (see Typical Installations below). All versions are available in a compact plug-in case utilizing industry-standard 8 or 11 pin octal sockets. Refer to the table below for more information, then click either the Type or Series to see details about a specific product type. If you have any questions regarding the selection or application of current monitor relays
