The ECS is excellent for new installations, where the conductors run through the housing, requiring no cutting. These switches are also ideal for retrofits, since split-core models can be opened to fit around existing conductors. The current switch is accurate, reliable and easy to install. The ECS can sense continuous currents from 1 to 150A and does not require any supply voltage, as the power required is induced from the monitored conductor. The output is a non-polarity-sensitive solidstate contact for switching AC and DC circuits up to 240 Vac/dc. This switch also includes an LED indicating two states: on and below trip point, and above trip point with contacts energized. All ECS Series switches carry an unconditional five-year warranty. For the most current information on this product, visit our Web site: www.eaton.com V8-T7-8 Any change in current can be sensed with the ECS Series. A change in current may indicate motor failure, belt loss/slippage or mechanical failure. Any of these events can cause the current to drop significantly, tripping the switch and notifying the controller. Example Application-- Pump Jam and Suction Loss Protection PLC Jam Motor Off Time Motor Starter Typical Applications Electronic Proof of Flow--Current operated switches eliminate the need for multiple pipe or duct penetrations and are more reliable than electromechanical pressure or flow switches Conveyors--Detect jams and overloads Lighting Circuits--Easier to install and more accurate than photocells Fans, Pumps and Heating Elements--Faster response than temperature sensors Critical Motors Ancillary Equipment Overload Setpoint Normal Operation Digital Input Motor Control Signal Application Description AMPS ECS Series CurrentWatch Current Switches B/I Card 7 Current Switch Features Universal Outputs--NO or NC solid-state switch for control circuits up to 240 Vac/dc, compatible with most automation systems Self-Powered--Cuts installation and operating costs Easily Adjustable Setpoint--Increases application flexibly and speeds start-up Solid- or Split-Core Housings--Versions tailored for each type of installation LED Indication--Provides quick visual indication of contact status Built-In Mounting Feet-- Simple, two-screw panel mount or attach with optional DIN-rail mounting kit accessory For Customer Service in the U.S. call 1-877-ETN CARE (386-2273), in Canada call 1-800-268-3578.

The EACR Series provides True RMS output on distorted waveforms found on VFD or SCR outputs, and on linear loads in "noisy" power environments. Available in solid- or split-core housings. Typical Applications VFD Controlled Loads-- Monitoring VFD output indicates how the motor and attached load are operating SCR Controlled Loads-- Accurate measurement of phase angle fired or burst fired (time proportioned) SCRs, with faster current measurement than temperature sensors Switching Power Supplies and Electronic Ballasts--True RMS sensing is the most accurate way to measure power supply or ballast input power 7 7 7 7 7 7 7 7 For typical applications of the CurrentWatch EACR Series, see listing on this page. 7 7 7 7 7 7 7 7 7 7 Example Application-- Current Sensing for Non-Linear AC Loads 137.2A Two-Wire Installation Is Fast and Easy Controller True RMS Output even on VFDs or SCRs Field Selectable Ranges 54.7Hz L I N E Motor VFD Features Why "True RMS"? The current waveform of a typical linear load is a pure sine wave. In VFD and SCR applications, however, output waveforms are rough approximations of a sine wave. There are numerous spikes and dips in each cycle. The CurrentWatch EACR Series current sensors use a mathematical algorithm called "True RMS" which For the most current information on this product, visit our Web site: www.eaton.com V8-T7-30 integrates the actual waveform over time. The output is the amperage component of the true power (heating value) of the AC current waveform. True RMS is the only way to accurately measure distorted AC waveforms. Select the EACR Series sensors for nonlinear loads in "noisy" power environments. True RMS Output--True RMS technology is accurate on distorted waveforms like VFD or SCR outputs Jumper-Selectable Ranges--Reduces inventory and eliminates zero and span Isolation--Output is magnetically isolated from the input for safety and elimination of insertion loss (voltage drop) UL, cUL and CE Approved--Accepted worldwide For Customer Service in the U.S. call 1-877-ETN CARE (386-2273), in Canada call 1-800-268-3578.

Ground fault sensors help protect people, products and processes from damage by ground fault conditions by monitoring all current-carrying conductors in grounded singleand three-phase delta or wye systems. Typical Applications Personnel Protection (Typically 5 mA)--Detects sensitive ground fault conditions, which could cause injury to people, and functions as a sensor and alarm trigger when applied as an input to an overall ground fault protection system Equipment Protection (Typically 10 or 30 mA)-- For applications where personnel protection is not the primary concern, higher setpoint capability helps eliminate nuisance tripping while still providing adequate ground fault detection to protect machine electronics Regulatory--Meets requirements as stipulated by governmental and industrial regulatory groups for ground fault sensing The EGF Series with solidstate outputs offers the benefit of reliable, longlasting solid-state switches. Solid-state design provides unlimited switch operating life, superior resistance to shock and vibration, zero offstate leakage, high switch speeds and high input-output isolation. The EGF Series with mechanical relay outputs is available in solid-core housings with a choice of NO or NC SPST latching relays and a SPDT Form C relay with auto-reset. 7 Example Application--Insulation Breakdown Monitoring Ground Fault Sensor 7 7 7 7 Circuit Interruption Device Shunt Trip Breaker For example, Contactor Leakage to Ground 7 7 7 "Zero Sequence" Operating Principle In three-phase delta and wye soon as current leaks to systems, under normal ground (fault condition), the conditions, current in the two currents become "hot" leg of a two-wire load imbalanced and a net is equal in magnitude but magnetic field results.

As a result, sensors monitor this field and the electromagnetic fields trip the contacts when the surrounding these two leakage rises above the conductors cancel, producing setpoint. a "zero sum current."
