787-3861 24 VDC, one-channel electronic circuit breaker (ECB) features LED indicators to identify device status and the ability to configure all S2 output variants. Its output configuration is ...

As the impedance of the LED circuit is generally much higher than the load, the majority of the supply voltage is applied to the LED circuit. No terminations for the neutral/0 V are required. The ...

This circuit can be easily modified to produce a siren in fuse-blown condition (see Fig. 2). An optocoupler is used to trigger the siren. When the fuse blows, red LED glows. Simultaneously it switches ...

Although IC CD4017 is a decade counter, it can be used in a variety of ways. In this programmable LED indicator circuit, it has been used to program a bicolour LED indicator in 10 different modes ...

The catalog includes new UL1077 Standard Circuit breakers. These new supplementary protectors are available in 1, 2 and 3 poles with the option of B, C and D curve. They carry a minimum amp rating of ...

In addition to the interface, the device has bright LED indicators that show clear visual cues during testing -- green for ...

Based on data center and weighting method of combination with indicators, a comprehensive assessment method is proposed to evaluate the operating status of high voltage circuit breaker equipment in ...
