Description
The ATQR3 Time Delay Fuse is a Class CC, full-range time-delay (slow-blow) industrial fuse designed to protect electrical circuits that experience high inrush current, such as control transformers, solenoids, and motor control systems. It allows temporary surge currents to pass safely while still protecting against overloads and short circuits.
It belongs to the Mersen Amp-Trap ATQR series, which is widely used in industrial control panel protection systems.
Key Features
- Time-delay (slow-blow) characteristic for inrush current protection
