ACI ECMCS25-A : Split-Core Adjustable Trip Point ECM Current Switch, Designed for ECM Motors, Amperage Range 0-25A, Lowest Industry Trip point of 0.075 to 0.5A, Contact Rating: 0.1A @30 VAC/DC, Made in USA, 5-Year Warranty
Precision Adjustable Current Switch for ECM Motors
The ACI ECMCS25-A split-core current switch is designed specifically for electronically commutated motors (ECMs), offering exceptional accuracy in motor status monitoring. Unlike traditional PSC motors, ECMs maintain a small standby current, making the ECMCS25-A indispensable for reliable operation tracking.
Key Features:
- Adjustable Trip Point: Industry-leading sensitivity with a trip range of 0.075A to 0.5A, ensuring precise motor activity detection.
- Power-Free Operation: No external power source is needed—the switch draws power directly from the monitored conductor.
- Versatile Installation: Compact split-core design with an integrated cable tie anchor and a mounting foot for effortless setup on flat surfaces or 35mm DIN rails.
- Durable Build: Made with flame-rated PC/ABS material (UL94-V0) for long-lasting performance.
- Amperage Range: Monitors currents from 0 to 25A, compatible with most ECM applications.
- USA-Made Quality: Backed by a 5-year limited warranty.
Installation Made Easy:
The ECMCS25-A comes with a calibration tool for a visual indication of output state, simplifying the setup process. The compact design ensures easy mounting with minimal space requirements.
Note: This product is not designed for variable frequency drive (VFD) motor applications or life safety environments.

Datasheets
Automation Components Inc. (hereafter "ACI") provides either a five (5)-Year Limited Warranty or a two (2)-Year Limited Warranty to the initial purchaser of any product manufactured by ACI based on the product category. Specific warranty durations can be found on corresponding data sheets at www.workaci.com. The term "product manufactured by ACI" means any sensors and transmitters assembled by ACI, even if such sensors and transmitters include component parts manufactured by companies other than ACI. For any part or product sold by ACI, but manufactured entirely by a company other than ACI, whether or not relabeled with ACI product information or product number, or repackaged with ACI information, ACI provides a two (2)-Year Limited Warranty to the initial purchaser. With regard to parts or product manufactured entirely by a company other than ACI, if the original manufacturer's warranty is longer than 2 years, it will be assigned to the initial purchaser, to the extent such
original manufacturer's warranty allows for such assignment.
During the Limited Warranty periods expressed above, ACI warrants that beginning on the date the initial purchaser receives products from ACI, such products will be (i) free from defects in workmanship; and (ii) free from defects in materials. The term "free from defects in workmanship" means that all products will conform to product specifications and function as described in catalogs, sales brochures, or other materials supplied by ACI. The term "free from defects in materials" means that the product will be free of material defects.
In the event any defect(s), as defined above, manifests itself or is discovered within the five (5) or two (2) year limited warranty periods set forth above, ACI will, at its sole discretion, do one of the following:
1 Repair the defective product;
2 Replace the defective product; or
3 Refund to the purchaser, the amount charged by ACI for the original product.
The choice of which of the above remedies will be provided to the purchaser by ACI, pursuant to this Limited Warranty, shall be solely in the discretion of ACI.
THESE FIVE (5) YEAR OR TWO (2) YEAR LIMITED WARRANTIES SET FORTH ABOVE, PROVIDED TO THE INITIAL PURCHASERS OF ACI PRODUCTS, ARE MADE IN LIEU OF ALL OTHER EXPRESS OR IMPLIED WARRANTIES, INCLUDING THE IMPLIED WARRANTY OF FITNESS FOR A PARTICULAR PURPOSE AND MERCHANTABILITY. ANY OTHER IMPLIED WARRANTIES CREATED BY COMMON LAW IN ANY JURISDICTION, ARE ALSO EXPRESSLY WAIVED AND DISCLAIMED. THIS LIMITED WARRANTY APPLIES TO THE ORIGINAL PURCHASER OF PRODUCT FROM ACI AND TO ANY SUBSEQUENT PURCHASERS OF THE SAME PRODUCT, BUT THE LIMITED WARRANTY PERIODS COMMENCE TO RUN ON THE DATE ACI'S PRODUCTS ARE DELIVERED TO THE INITIAL PURCHASER.
