Mersen A60X151 Amp-Trap High Speed Fuse, 500VAC/500VDC Rated

The Mersen A60X151 Amp-Trap® High Speed Fuse is a Form 101 semiconductor fuse engineered to protect dynamic solid-state equipment such as motor drives, inverters, and UPS systems. This family is available with your choice of Blade or Ferrule termination, so the same proven Amp-Trap® performance can be specified for the connection style your enclosure requires. Every option in this family carries the same dual 500VAC and 500VDC (UL) rating with a high-speed characteristic at 50/60 Hz, delivering lower I²t let-through for improved equipment protection, longer service life under cyclic loading, and lower watts loss compared to earlier semiconductor fuse designs. The fuses are RoHS compliant and packaged 20 EA per box for professional electrical and industrial supply applications.

Key Features

  • Connection Options: Available in Blade or Ferrule termination styles to match your equipment's mounting requirements.
  • Dual Voltage Rating: Rated 500VAC and 500VDC (UL) for use across AC and DC power electronics applications.
  • High-Speed Protection: High-speed characteristic engineered for fast clearing of fault currents in semiconductor circuits.
  • Lower I²t Performance: Reduced I²t let-through provides better protection for sensitive dynamic solid-state equipment.
  • Extended Cyclic Life: Engineered for longer life when subjected to cyclic loading versus standard semiconductor fuses.
  • Lower Watts Loss: Improved efficiency reduces heat generation and watts loss in the fuse itself.
  • Form 101 Design: Amp-Trap® Form 101 construction purpose-built for motor drives, inverters, and UPS protection.
  • Frequency Rating: Rated for 50/60 Hz power systems.
  • Packaging: Supplied 20 EA per box for stocking and resale.

Mersen A60X15-1 – Frequently Asked Questions

1) Can the Mersen A60X151 Amp-Trap fuse be used on a DC bus, or is it AC only?
Both. The A60X151 Amp-Trap high speed fuse carries a dual rating of 500VAC and 500VDC (UL), so it works on the DC link of a drive or UPS as well as on the AC input side. The AC rating applies at 50/60 Hz.
2) Do I order the blade or the ferrule version of the A60X151 fuse?
That depends on the holder in your equipment. The Amp-Trap A60X151 family is offered in two terminations: a blade (bolt-down tag) style, ordered as A50QS100-4, and a ferrule (cylindrical end cap) style, ordered as A60X15-1. Ferrule fuses drop into clip-type or cylindrical fuse holders; blade fuses bolt to busbar or stud mounting pads. Check how the existing fuse is secured in the drive or panel before picking.
3) Is a high speed semiconductor fuse like the Amp-Trap A60X151 the right choice to protect a VFD, or should I use a standard Class CC or midget fuse?
For solid-state protection, go with the semiconductor fuse. The A60X151 is a Form 101 high speed Amp-Trap built to clear fast enough to save diodes, IGBTs and SCRs in motor drives, inverters and UPS systems, with lower I2t let-through than earlier semiconductor designs. Ordinary branch-circuit fuses do not clear fast enough for that job. A time-delay Class CC such as the Littelfuse CCMR040 is for motor branch circuits where inrush must be ridden through, and a midget fast-acting fuse like the Littelfuse BLF Series is a 250V control-circuit part, neither is a substitute for semiconductor protection.
4) If I need a RoHS compliant fuse for a 500VDC solid-state circuit, which option fits?
The Mersen A60X151 Amp-Trap is the fit: it is RoHS compliant and carries a 500VDC (UL) rating along with a high-speed characteristic for semiconductor protection, in Blade or Ferrule termination. Among the alternatives, the Littelfuse BLF is a 250V midget fast-acting fuse and the Littelfuse CCMR040 is a Class CC time-delay fuse, neither of which matches a 500VDC high-speed requirement.
5) What does Form 101 mean on the Mersen Amp-Trap fuse?
Form 101 is Mersen's body style and construction designation for this Amp-Trap semiconductor fuse. It tells you the physical form and performance class of the fuse rather than a safety grade, and it is what you match when replacing an existing Amp-Trap in a drive, inverter or UPS so the new fuse fits the same holder and behaves the same electrically.
6) Will a glass tube fuse work in place of a Mersen semiconductor fuse?
No. Glass tube fuses such as the Littelfuse AGA Series 5A or the AGU Series are small automotive and appliance-style parts, not 500V semiconductor protection. The Amp-Trap A60X151 is rated 500VAC/500VDC with a high speed characteristic for power electronics, and swapping in a glass fuse leaves the drive or inverter unprotected and the fuse over-stressed on voltage.
7) Is a Littelfuse BLF midget fast-acting fuse an equivalent to the Mersen A60X151?
They serve different circuits. The Littelfuse BLF series is a midget fast-acting fuse rated 250V in a laminated tube body. The Mersen A60X151 Amp-Trap is a Form 101 semiconductor fuse rated 500VAC and 500VDC (UL) at 50/60 Hz. If the equipment calls for a 500V DC-rated semiconductor fuse, a 250V midget fuse does not meet the voltage requirement, and a fast-acting midget is not the same as a high-speed semiconductor element.
8) What should I use instead of the Mersen A60X151 for a low-amperage glass-fuse holder in automotive or appliance wiring?
The A60X151 Amp-Trap is a Form 101 semiconductor fuse for 500V power electronics and is not intended for small glass-tube holders. For AG-style glass tube holders, the Littelfuse AGA series includes a 5A glass fuse, and the Littelfuse AGU series is an AG glass tube fuse supplied in a boxed package. Confirm the holder clip spacing matches the AG body you select.
9) Will the Mersen A60X151 work as a replacement fuse for a Square D PowerLogic energy meter?
No. The Square D PowerLogic energy meter fuse pack is a set of three 0.5A 600V fuses sized for metering voltage inputs. The Mersen A60X151 Amp-Trap is a high-speed semiconductor fuse rated 500V, built for motor drive, inverter, and UPS power circuits, and comes in Blade or Ferrule termination. Use the PowerLogic meter fuse pack for meter sensing circuits and the Amp-Trap for the power stage.
10) Is the A60X151 Amp-Trap fuse RoHS compliant for our spec submittals?
Yes, the A60X151 Amp-Trap high speed fuse is RoHS compliant, and RoHS is the standard recorded against it. That covers the common restricted-substance requirement on institutional and OEM submittals.
11) How are these Mersen Amp-Trap fuses packaged if I want to stock them?
They ship 20 each per box, which suits distributors and MRO storerooms keeping spares on the shelf for drive and UPS service calls.
