Mersen A70P Amp-Trap High Speed Fuse, Bolted Blade Terminal, 700VAC

The Mersen A70P Amp-Trap Form 101 is a high speed fuse engineered for higher voltage AC and DC drives, UPS systems, reduced voltage motor starters, and similar applications where low l2t and superior reliability are critical. Rated 700VAC with a bolted blade terminal connection and a GMG insulating body, this A70P series is offered across a Motor FLA range of 15A, 25A, 30A, 35A, 50A, 60A, 80A, 100A, 125A, 200A, 250A, 300A, and 400A, allowing engineers and electricians to select the exact current rating required for a given drive, UPS, or motor starter circuit. Every rating in the series shares the same 700VAC voltage rating, bolted blade terminal design, GMG insulating body, and 50/60 Hz frequency rating, making the A70P a popular, consistent platform for both new installations and direct replacement in existing fuse blocks and disconnect switches. RoHS compliant construction and high speed, low l2t let-through performance help protect sensitive semiconductors and power electronics from damaging fault currents across the entire rating range.

Key Features

  • Current Rating Range: Available across Motor FLA ratings from 15A through 400A (15A, 25A, 30A, 35A, 50A, 60A, 80A, 100A, 125A, 200A, 250A, 300A, 400A) to match specific drive and starter load requirements.
  • Connection/Terminal Type: Blade terminals provide a secure, low-resistance bolted connection for demanding industrial circuits, consistent across every rating in the series.
  • Mounting: Bolted mounting configuration for stable, vibration-resistant installation in fuse blocks and disconnects.
  • Voltage Rating: 700VAC rating suits higher voltage AC and DC drive systems, UPS equipment, and reduced voltage motor starters, and applies uniformly across all current ratings.
  • Speed/Characteristic: High speed operation with low l2t let-through energy for superior protection of semiconductors and drive components at any rating.
  • Body/Insulating Material: Durable GMG insulating body supports reliable performance across the fuse's rated life, shared by every current rating.
  • Frequency: Rated for standard 50/60 Hz electrical service.
  • Availability: Offered across a wide range of Motor FLA current ratings, making the A70P a popular choice for direct replacement.

Mersen A70P30-4 – Frequently Asked Questions

1) Can a Mersen A70P Amp-Trap high speed fuse be used on a 480V or 600V drive, or is it only for 700V systems?
The A70P Amp-Trap is rated 700VAC, which is a maximum rating, so it covers 480V and 600V drive circuits as well as 700V systems. It is built for higher voltage AC and DC drives, UPS equipment and reduced voltage motor starters, and runs on standard 50/60 Hz service. Every current rating in the series carries the same 700V rating, so stepping up or down in amps does not change the voltage capability.
2) What amp ratings does the Mersen A70P series come in?
Ratings run 15A through 400A: 15, 25, 30, 35, 50, 60, 80, 100, 125, 200, 250, 300 and 400 amps. Part numbers follow the pattern A70P15-4 for 15A, A70P125-4 for 125A, A70P400-4 for 400A, so you can match the exact rating your drive or starter circuit calls for without changing the fuse platform.
3) Is a high speed semiconductor fuse like the A70P the right choice, or should I use a standard time-delay fuse?
Pick based on what you are protecting. The A70P is a high speed fuse with low I2t let-through, which is what semiconductors, SCRs, IGBTs and drive power sections need because they fail faster than a conventional fuse will clear. A time-delay fuse such as the Littelfuse CCMR Series Class CC is built to ride through motor inrush on branch circuits instead, and will not protect power electronics. Use high speed on the DC bus and drive input, time-delay for motor starting loads.
4) I need to replace a failed semiconductor fuse in a UPS cabinet. Will a different amp rating of the A70P fit the same mounting?
Within the A70P family the platform is consistent, every rating uses the same 700VAC rating, bolted blade terminal, GMG body and 50/60 Hz rating. Physical dimensions do still step up with current rating, so match the amp rating and center-to-center hole spacing of the fuse you pulled out. Read the old fuse label and order the matching A70P number, for example A70P100 class ratings are listed by Motor FLA on the series.
5) Is the Mersen A70P a glass tube or automotive style fuse?
No. The A70P Amp-Trap is an industrial bolt-in high speed fuse with a GMG insulating body, used in drives, UPS systems and motor starters. Glass tube fuses like the Littelfuse AGA and AGU Series are small electronic and automotive style parts, and the Littelfuse BLF Series is a 250V midget fast-acting fuse in a laminated tube. None of those are interchangeable with a 700V bolted blade semiconductor fuse.
6) Can I use the A70P on a DC bus, or is it AC only?
The A70P Amp-Trap is applied in both higher voltage AC and DC drive systems. Its published voltage rating is 700VAC at 50/60 Hz, so for a DC application confirm the DC voltage rating against the manufacturer's data for the specific amp rating before committing.
7) Is the Mersen A70P RoHS compliant for an export or spec-driven project?
Yes, A70P Amp-Trap fuses are RoHS compliant, which covers most specification and export documentation requirements for restricted substances. The body is a GMG insulating material.
