Alternating current (ac) or direct current (dc) circuits are capable of carrying very different currents, as illustrated by the ratings on the switch in Figure 1. This is why it’s so important for ...

When choosing a switch to use in an electrical design project, there is a perception that it is possible to use any switch, provided its current rating is greater than the maximum load in the circuit.

A load switch is simply a switch, mechanical or electronic, that connects or disconnects a load to the high side of a power source. A wall light switch is a load switch. Any off/on switch on an ...

Designed for manual or remote operation Can be removed and parts replaced Load switching capability Magnum DC switches provide DC disconnect and switching technology in a common power breaker platform ...

The lightweight, portable CBS ArcSafe RSA-22 allows technicians to remotely close or trip the load break switch from a safe distance. CBS ArcSafe has introduced its remote switch actuator (RSA) for ...

You use an active-load test circuit to ensure that a power supply for a microprocessor or for other digital loads supplies 100A transient currents. This active load can provide a dc load for a power ...
