AutomationDirect has added the new ProSense T2 series of multi-mode, on-delay, off-delay, fleeting, and on-interval timer relays. These low-cost relays have a compact design with easy-to-use ...

This circuit is designed to provide delayed relay switching action at power on. The delay is a function of the time constant produced by the combination of R1 and C1. At power on, C1 charges slowly ...

Time Delay Control Switch Relay (TD-CSR) from Electroswitch provides a safe and effective means of mitigating arc flash danger in local circuit breaker operation by allowing for a manually initiated ...

New ProSense multi-mode and off-delay timer relays offer the flexible programmability of a multi-function and multi-range time delay relay together with a universal input voltage. The TRM series multi ...

A transformer switching onto a line can sometimes cause a circuit breaker to trip or a fuse to blow. This phenomenon occurs even if the transformer presents no load, such as when the secondary is open ...
