Current Monitor Relays from Macromatic

Current Monitor Relays (also known as Overcurrent Relays & Undercurrent Relays) are used in a variety of applications where protection of sensitive or expensive equipment against over or under current conditions is required. These products are perfect for applications such as detecting (sensing) conveyor jam-up conditions, machine tool wear, no load conditions or monitoring status of heater or lamp load.

Innovative Design

Macromatic current monitor relays utilize a microprocessor-based design for greater performance and maximum flexibility. The internal relay will energize when the monitored AC current is above the pick-up setting and will de-energize when the current is below the drop-out setting. An adjustable time delay on either pick-up or drop-out can be selected to avoid nuisance tripping issues. An external current transformer may be used to extend the range of these products (for more information, read our KnowledgeBase Article).
