The CurrentWatch™ ECS series from eaton electrical sector is a family of solid state adjustable current switches, ideal for providing status information on electrical equipment. 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 150 A and does not require any supply voltage, as the power required is induced from the monitored conductor. The output is a non-polarity sensitive solid state 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 5 years warranty. 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.
