Do you know the facts about circuit protection, or have you just been relying on what you hear around the shop? As an electrical contractor, system designer, plant electrician, or electrical inspector ...

Note: This article is based on the 2011 NEC. Overcurrent exists when current exceeds the rating of equipment or the ampacity of a conductor. This can be due to an overload, short circuit, or ground ...

This circuit provides latching and high-speed overcurrent protection for power-factor corrected (PFC) boost converters operating at dc voltages to 380 V. Overcurrent damage of PFC front-end boost ...

Circuit protection has become a crucial design consideration to protect sensitive applications against overcurrent conditions. In most applications, overcurrent and overtemperature conditions are an ...
