Mersen ATDR3 Amp-Trap 2000® 600V 3A Time-Delay Class CC Fuse, 1.5 Inch Length, 0.41 Inch Diameter

Description

Features

• The ATDR3 is a 3-Amp, 600V AC/300V DC Class CC time-delay fuse from Mersen's Amp-Trap 2000® series. It features a specialized rejection tip-a physical protrusion on the end-that prevents the installation of non-rejection or lower-rated midget fuses into critical branch circuits, ensuring your system remains protected by the exact safety specifications required.
• Specifically engineered for small motor and control transformer protection, the ATDR3 provides superior time-delay characteristics. It is designed to "ride through" the high initial current surges of motor startups without nuisance tripping, while still offering ultra-fast, current-limiting protection during actual fault conditions.
• This fuse provides IEC Type 2 "no damage" protection, meaning it can stop a massive electrical fault in less than half a cycle ($<0.008$ seconds). With a 200,000 Amp RMS interrupting rating, it drastically limits the "let-through" energy ($I^2t$) during a short circuit, preventing catastrophic damage to sensitive downstream components like contactors and solid-state relays.
• The ATDR3 is constructed with a high-grade fiberglass body and silver-plated copper contact caps, ensuring excellent dimensional stability and electrical conductivity. This robust build prevents the fuse from becoming brittle or losing calibration when housed in compact, high-temperature control panels or HVAC units.
• The Mersen ATDR3 is UL Listed to Standard 248-4 (Class CC) and CSA Certified to Standard C22.2. Its high interrupting capacity and exceptional cycling ability make it the primary choice for meeting NEC® and CEC® requirements for branch circuit protection in industrial machinery, automation cabinets, and commercial lighting systems.
