Why Choose the Mersen ATQR1/8 Time-Delay Fuse?
The Mersen ATQR1/8 is a 0.125 A Class CC time-delay fuse designed to protect sensitive industrial control circuits, control transformers and other low-current equipment exposed to temporary inrush currents. As part of the Mersen Amp-Trap 2000® ATQR series, it combines time-delay operation, current-limiting performance and a compact rejection-style cartridge design.
Rated at 600 V AC and 300 V DC, the ATQR1/8 accommodates brief, non-damaging current surges generated when transformers, relays, solenoids and similar inductive devices are energised. This helps minimise nuisance fuse operation while maintaining dependable protection against sustained overloads and short-circuit faults.
The fuse uses a standard Class CC rejection cartridge format, helping prevent substitution with an incorrectly classified fuse. When installed in a suitably rated Class CC fuse holder, the ATQR1/8 provides compact branch-circuit protection for industrial control panels, automation systems, instrumentation and OEM machinery.
Key Advantages
- Class CC branch-circuit protection for industrial control equipment.
- 0.125 A current rating for sensitive low-current circuits.

Reliable Protection for Sensitive Control Circuits
Low-current control transformers and inductive components can draw a temporary energisation current considerably higher than their normal operating current. The time-delay characteristic of the Mersen ATQR1/8 allows these brief inrush conditions while responding to sustained overloads that could damage wiring or connected equipment.
During a severe fault, its current-limiting construction rapidly restricts the amount of energy passed into the circuit. This helps reduce thermal and mechanical stress on conductors, terminals and downstream components while supporting dependable operation in compact industrial control panels.
Typical Applications
- Industrial control transformers.
- PLC and automation control panels.
- Instrumentation and monitoring circuits.
- Relay and solenoid circuits.
- OEM machinery and process equipment.
- Low-current industrial branch circuits.

Frequently Asked Questions
What is the Mersen ATQR1/8 used for?
The ATQR1/8 protects sensitive industrial control circuits, control transformers, relays, solenoids and instrumentation against sustained overloads and short-circuit faults.
What is the current rating of the Mersen ATQR1/8?
The Mersen ATQR1/8 has a rated current of 0.125 A, which is equivalent to one-eighth of an ampere.
What voltage is the ATQR1/8 rated for?
The fuse is rated for systems up to 600 V AC and 300 V DC.
Is the ATQR1/8 a Class CC fuse?
Yes. The ATQR1/8 is a Class CC time-delay, current-limiting fuse with a rejection-style cartridge for compatible Class CC fuse holders.
Can the ATQR1/8 be installed in a standard midget fuse holder?
The fuse should be installed in a correctly rated Class CC rejection fuse holder. Its rejection feature may prevent installation in an ordinary non-rejection midget fuse holder.
