- Self-powered operation eliminates external supply
- Adjustable trip point from 1.75 to 150 A covers wide range
- Split-core design allows installation without disconnecting conductors
- LED status indicator provides immediate visual feedback
- Fast 0.12 sec trip delay limits fault exposure
Adjustable Current Sensing Relay
The Eaton ECSNCASP is a self-powered relay that detects AC current from 1.75 to 150.00 amperes without an external supply. It suits installers who need a compact, split-core device for status monitoring or load-shedding circuits in electrical panels.
Compatibility Checklist
Verify the conductor fits the split-core opening and that the circuit voltage does not exceed 135 volts AC or DC at the relay contacts. Confirm a 0.12 second trip delay matches the protection scheme and that surface mounting with terminal-strip wiring is practical in the enclosure.
Integration Notes
The solid-state SPST-NC output opens when the adjustable trip point is reached, freeing the control circuit from continuous coil power. An LED indicator shows trip status at a glance, and the 2.25 by 3.53 by 1.19 inch body fits standard panel layouts without requiring a separate control transformer.

Questions about this item
What accessories or separate purchases are required to install the ECSNCASP relay?
The relay mounts on a surface and connects via its built-in terminal strip. No extra mounting hardware or wiring harnesses are listed in the specifications.
How do I decide which trip-point setting to use on the 1.75-150A adjustable range?
Set the trip point between 1.75 and 150.00A to match the current level at which you want the SPST-NC solid-state output to open.
What does the 0.20A @ 135V contact rating mean for my control circuit?
The solid-state output can switch up to 0.20 amps at 135 volts AC or DC, so the driven load must stay within that limit.
