Why Choose the Mersen ATQR1-4/10 Class CC Fuse?
The Mersen ATQR1-4/10 is a premium Class CC time-delay fuse designed to provide dependable overcurrent protection for industrial control transformers, solenoids, relays and other inductive loads. As part of the proven Mersen Amp-Trap® 2000 ATQR series, it delivers excellent current-limiting performance while withstanding the temporary inrush currents associated with transformer energisation and motor control circuits.
Its time-delay characteristic helps minimise nuisance fuse operation during normal equipment start-up while rapidly interrupting overloads and short circuits. The rejection-style Class CC construction also prevents incompatible fuse replacement when installed in a suitable Class CC fuse holder, improving electrical safety and system reliability.
With a rated current of 1.4 A, a maximum voltage rating of 600 V AC and a 300 V DC rating, the ATQR1-4/10 is ideally suited to industrial control panels, OEM machinery and automation systems requiring dependable branch circuit protection.
