Over current detectors
E-T-A Circuit Breakers has announced the extension of its product offering to include a line of over current detectors. The TD and 9001 Hall effect current detectors protect power semiconductors in power electronic circuits by signaling when current in the circuit has exceeded the nominal detector trip point. They provide isolation between the sensed current and the output. Both have a response time of 1 ¼s (typical) and operate over -40° to 125ºC.
