Why Choose the Mersen ATQR3/16 Class CC Fuse?
The Mersen ATQR3/16 is a high-performance Class CC time-delay fuse engineered to provide dependable overcurrent protection for industrial control transformers, relays, solenoids and other inductive electrical loads. As part of the trusted Mersen Amp-Trap® 2000 ATQR series, it combines advanced current-limiting technology with a time-delay characteristic that withstands temporary inrush currents while delivering rapid protection against sustained overloads and short circuits.
Designed specifically for industrial branch circuit protection, the ATQR3/16 helps eliminate nuisance fuse operation during transformer energisation while protecting valuable control equipment from damaging fault currents. Its rejection-style Class CC design also helps prevent incompatible replacement fuses from being installed when used with an appropriate Class CC fuse holder.
With a rated current of 0.187 A (3/16 A), a maximum voltage rating of 600 V AC and 300 V DC, the ATQR3/16 is ideally suited to sensitive industrial control circuits requiring accurate low-current protection.
