Why Choose the Mersen ATDR1/4 Class CC Fuse?
The Mersen ATDR1/4 is a premium 0.25 A Class CC time-delay fuse designed to provide reliable overcurrent and short-circuit protection for industrial control circuits, instrumentation and sensitive electrical equipment. As part of the trusted Mersen Amp-Trap 2000 ATDR series, it delivers outstanding current-limiting performance while accommodating temporary inrush currents associated with transformers, relays and small motors.
Its dual-element time-delay construction helps prevent nuisance fuse operation during normal equipment start-up while rapidly clearing sustained overloads and fault currents. The compact Class CC design allows panel builders and OEMs to maximise valuable enclosure space without compromising electrical protection.
With a rated current of 0.25 A and voltage ratings of 600 V AC and 300 V DC, the ATDR1/4 is ideally suited to industrial control panels, automation systems, branch circuits and low-current electrical applications requiring dependable circuit protection.

Reliable Protection for Industrial Control Circuits
The Mersen ATDR1/4 interrupts excessive current before wiring and connected equipment can sustain thermal or mechanical damage. Its highly current-limiting design significantly reduces the fault energy transmitted through the circuit during a short circuit, helping protect expensive control components and minimise downtime.
The fuse's time-delay characteristic allows harmless temporary current surges associated with transformer energisation and small motor starting while providing rapid interruption of sustained overloads. This makes the ATDR1/4 particularly suitable for industrial automation, instrumentation and control panel applications.
Typical Applications
- Industrial control panels.
- Instrumentation and monitoring equipment.
- Control transformers.
- Relays and contactors.
- Small motors.
- Branch circuit protection.
