MERSEN FERRAZ ATDR2 Fuse Atdr 2 Amp 600vac 1p

Mersen Ferraz ATDR2 fuse is used in electrical circuits to provide precise time-delay protection against overcurrent conditions, ensuring the uninterrupted operation of sensitive machinery and equipment. This fuse is used in small motors, contactors, lighting, heating & general loads and branch circuit protectors.

Working Mechanism:

• This Mersen Ferraz ATDR2 fuse operates based on a time-delay mechanism.
• When the current flowing through the fuse exceeds its rated limit, a heat buildup occurs within the fuse element.
• This heat causes the fuse element to melt or open, interrupting the circuit.
• This delay prevents immediate fuse tripping, ensuring the uninterrupted operation of equipment while offering reliable protection against sustained overcurrent events.

Features:

• This fuse features a time delay to accommodate motor starting inrush currents and has improved cycling ability for frequent motor starts / stops without nuisance fuse opening.
• This fuse offers the high current limiting capability for low peak let-thru current.
• It offers a rejection-style design to prevent replacement errors when used with recommended fuse blocks.
• This fuse offers fibreglass body that provides dimensional stability in harsh industrial settings.
• It has a high-grade silica filler to ensure fast arc quenching and optimum current limitation.

Frequently Asked Questions:

Q. Does the ATDR2 Fuse come with any safety or identification features?

A. Yes, it features a high-visibility orange label for easy recognition and the metal-embossed date and catalogue numbers for traceability and lasting identification.

Q. What safety precautions should I take when installing or replacing the ATDR2 Fuse?

A.

• De-energise the circuit by turning off the power supply and verifying its status.
• Follow lockout / tagout procedures to prevent accidental power restoration.
• Confirm you have the correct replacement fuse with the right ratings.
• Visually inspect the fuse holder or block for damage or wear before installation.
• Safely discharge capacitors to prevent electrical shocks.
• Adhere to the manufacturer's installation and replacement guidelines.
• Allow equipment to cool down if it was recently in operation.
• Use a torque wrench or recommended torque values when securing the fuse.
• Ensure the circuit is not overloaded and address underlying issues causing repeated fuse blows.
• Inspect wiring for damage or wear while working on the circuit.
• Have a suitable fire extinguisher for electrical fires nearby.

Q. What is the difference between a time-delay fuse and a fast-acting fuse?

A. Time-delay fuse has a built-in delay to withstand temporary current surges, ensuring equipment starts smoothly, while fast-acting fuses respond immediately to overcurrents, providing rapid protection against short circuits and overloads.
