MERSEN FUSE CC TD FUSE 600V 1/2A ATDR ATDR1/2

Why Choose the Mersen ATDR1/2 Class CC Fuse?

The Mersen ATDR1/2 is a compact 0.5 A Class CC time-delay fuse designed to protect industrial control circuits and electrical equipment against overloads and short circuits. As part of the Mersen Amp-Trap 2000 ATDR series, it combines current-limiting protection with the ability to tolerate brief, harmless inrush currents.

Its time-delay operating characteristic helps prevent unnecessary fuse operation during normal transformer energisation, control-circuit start-up and other temporary current surges. The ATDR1/2 remains responsive to sustained overloads and high-level fault currents, helping protect conductors, controls and connected equipment.

With a rated current of 0.5 A and voltage ratings of up to 600 V AC and 300 V DC, the Mersen ATDR1/2 is suitable for low-current industrial control, instrumentation and branch-circuit applications. Its compact Class CC format also helps conserve space inside machinery panels and electrical enclosures.

Reliable Protection for Industrial Control Circuits

The Mersen ATDR1/2 interrupts excessive current before wiring and connected components sustain serious thermal or mechanical damage. Its current-limiting action restricts peak fault current and reduces the amount of energy passing through the protected circuit during a short circuit.

The time-delay characteristic allows the fuse to tolerate short-duration current surges while remaining sensitive to sustained overloads. This balance makes the ATDR1/2 suitable for low-current industrial controls, transformers, instrumentation and automation equipment requiring dependable branch-circuit protection.

Typical Applications

• Industrial control and automation circuits.
• Control transformers and power supplies.
• Instrumentation and monitoring equipment.
• Contactors, relays and solenoid circuits.
• Machinery and control panels.
• Low-current branch-circuit protection.
