WebLong time delay tripping settings. Go back to CB tripping settings ↑. 3. Short-Time Pickup. Short-time pickup is used for selective tripping. The short-time pickup function determines the amount of current the breaker will carry for a short period of time, allowing downstream protective devices to clear short-circuits without tripping the upstream device. WebMicrologic™ 3.2 Long Time Trip Curve 60A, 100A, 150A H-Frame The time-current curve information is to be used for application and coordination purposes only. Notes: 1. There is a thermal-imaging effect that can act to shorten the long-time delay. The thermal imaging effect comes into play if a current above the long-time delay pickup value exists

Webwww.mavtechglobal.com WebThe eclipsing binary IT Librae is an unusual system of two B-type stars that is situated about 1 kpc above the Galactic plane. The binary was probably ejected from its birthplace in the disk, but the implied time of flight to its current location exceeds the evolutionary lifetime of the primary star. Here we present a study of new high-dispersion spectroscopy and an …
WebDec 11, 2014 · A device’s time-current characteristics can be broken up into three different regions: Instantaneous – the initial period of an electrical fault, from zero up to several milliseconds. This portion of the device response is adjustable on more complex breakers. Short time – the period of time in the fault ranging from tenths of a second to ...
