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.
