Short circuit current rating 中文
Splet02. okt. 2024 · The short-circuit current rating is the maximum amount of RMS (Root-Mean-Squared) current an electrical component can handle when using an overcurrent protection device, such as a fuse, or for a given amount of time at a specified voltage. The SCCR rating applies both for individual electrical components and for entire electrical assemblies or ... Splet13. apr. 2024 · The GP2E series of manual motor controllers conform to UL 60947-4-1 and are suitably rated for motor disconnect (Figure 4). The series combines motor control with both thermal and magnetic current overload protection. Pushbutton start and stop controls, and user-selectable thermal current limits are accessible via the front panel.

SpletRated vs. Nominal Current Joel Goergen, 1/22/18 “Rated current” is defined by the following: Generally, rated means that the product is marked on the nameplate with the rating. E.g. 100-120Vac, 1A, 50/60Hz. Then, in most standards, there is an input current/power test where you verify that you do not exceed the rating by more than 10%. SpletThe current that a fuse in series with the device can continously pass through without opening. According to the comment below, the device marked with gG/gL is a Motor Starter Protector (MSP). This should be put in series with a fuse that won't trip unless a short circuit fault occurs. Not even a stalled motor should trip it.
