Mersen A6D Series Class RK1 Time-Delay Fuse, 600VAC/600VDC, SmartSpot

Mersen A6D Series Class RK1 Time-Delay Fuse, 600VAC/600VDC, SmartSpot

The Mersen A6D Series is a family of Class RK1 time-delay blade-type fuses from the Amp-Trap 2000 line, rated 600VAC and 600VDC for demanding industrial and commercial power distribution circuits and available across a range of ampere ratings to match specific feeder and branch circuit requirements. Built with a PolyTube body and tin-plated copper connection terminals, these fuses deliver dependable overcurrent protection with an AC max breaking capacity of 200 kA. An integrated SmartSpot® indication system gives technicians a fast visual check on fuse condition, reducing troubleshooting time during maintenance and outage response.

Key Features

• Dual Voltage Rating: 600VAC and 600VDC (UL) at 50/60 Hz for versatile AC/DC application.
• Class RK1 Time-Delay: Blade-type Amp-Trap 2000 construction engineered to ride through motor inrush and other temporary overloads before opening, reducing nuisance blows in motor circuits.
• SmartSpot® Indication System: Built-in visual indicator simplifies identification of a blown fuse without removal, speeding up troubleshooting during outages.
• Durable Construction: PolyTube body insulating material for reliable dielectric performance in demanding electrical enclosures.
• Connection Terminals: Tin-plated copper terminals for low-resistance, corrosion-resistant connections that hold up over repeated thermal cycling.
• Mounting Method: Clip-mount design for straightforward installation in compatible fuse blocks and disconnects.
• Breaking Capacity: 200 kA AC max interrupting rating (I1) for high fault-current environments where reliable clearing is critical.
