Why Choose the Mersen ATM30/50 Fast-Acting Fuse?
The Mersen ATM30/50 is a specialised fast-acting midget fuse designed to provide dependable supplementary overcurrent protection for industrial control systems, capacitor banks, power supplies and electrical equipment with exceptionally high inrush currents. As part of the trusted Mersen Amp-Trap® ATM series, it combines rapid fault interruption with enhanced surge withstand capability for demanding industrial applications.
Although designated ATM30/50, the fuse is electrically rated at 30 A with voltage ratings of 600 V AC and 600 V DC. The unique 30/50 designation identifies a special version engineered to withstand significantly higher inrush currents and tougher operating duty cycles than a standard ATM30 fuse, making it particularly suitable for capacitor protection and other surge-intensive applications.
Manufactured in the standard 10 × 38 mm midget fuse format, the ATM30/50 features a current-limiting design and is compatible with standard midget fuse holders and fuse blocks. Like all ATM-series fuses, it is intended for supplementary protection and is not approved for branch-circuit protection.

Engineered for High Inrush Current Applications
The Mersen ATM30/50 has been developed for applications where high repetitive inrush currents are expected. While maintaining a nominal current rating of 30 A, it withstands substantially greater energisation surges than a conventional ATM30 fuse, helping reduce nuisance operation in demanding industrial installations.
Its fast-acting current-limiting construction rapidly clears genuine fault conditions while providing dependable protection for capacitor banks, industrial controls and other equipment exposed to repeated surge currents.
Typical Applications
- Capacitor bank protection.
- Industrial control panels.
- Power supplies.
- Automation systems.
- OEM electrical equipment.
- Industrial circuits with exceptionally high inrush currents.
