Adjustable Current Sensing Relay 1.75–150 A

The Eaton adjustable current sensing relay monitors AC or DC circuits for overcurrent and undercurrent conditions. It offers a selectable trip range from 1.75 to 150 A using a switch-based adjustment method. The self-powered unit requires no separate input voltage and provides a single SPST-NO contact rated at .15 A at 240 V for control signalling.

Split-Core Design with Surface Mounting

A split core with a .85 in sensing hole allows installation around existing conductors without disconnecting wiring. Surface mounting suits panel or enclosure installations where DIN rail space is unavailable. Screw terminals accept 14 AWG wire for secure connections, and an integrated LED indicator shows relay status at a glance.

Replaces Fixed-Threshold or External-Power Relays

This relay upgrades installations that previously relied on fixed trip points or separate control transformers. The wide adjustable range covers multiple load sizes with one device, reducing inventory variants. The jump is worth it when a project demands flexible, self-powered monitoring with simple screw-terminal wiring and visual confirmation.

Questions about this item

How high can the 150 A adjustable trip point actually switch?

The relay contact is rated 0.15 A at 240 V AC or DC, so the 150 A setting only controls when the output closes — it does not carry the load current.

What size conductor fits through the 0.85 in sensing hole?

The split-core opening accepts wires up to 0.85 in diameter, covering most common feeder cables in this current range.

Which terminals do I use for the 14 AWG control wiring?

Two screw terminals accept 14 AWG wire for the SPST-NO output; the sensor itself is self-powered and needs no separate supply connection.
