Mersen ATDR20 Fuse Amp-Trap 2000 20A 600V Time-Delay Class CC, 1.5 Inch Length, 0.41 Inch Diameter

Description

Features

• The ATDR20 is a 20-Amp, 600V AC/300V DC Class CC time-delay fuse from Mersen s Amp-Trap 2000 series. It features the signature rejection tip, a physical safety feature that prevents lower-rated "midget" fuses from being installed in its place, ensuring the branch circuit remains protected to its high-performance design specifications.
• Designed specifically for small motor and control transformer protection, the ATDR20 provides exceptional time-delay characteristics. It is engineered to "ride through" the high initial current surges (inrush) of 20-Amp inductive loads without nuisance tripping, while still providing ultra-fast protection against actual fault conditions.
• This fuse is highly current-limiting, providing IEC Type 2 "No Damage" protection. In the event of a short circuit, it can interrupt the fault in less than half a cycle (<0.008 seconds). With a 200,000 Amp interrupting rating, it drastically reduces the energy (I^2t) that reaches downstream components, preventing catastrophic equipment failure.
• The ATDR20 is constructed with a high-grade fiberglass body and silver-plated copper contact caps. This robust build ensures dimensional stability and electrical reliability even in high-vibration or high-temperature environments, such as compact industrial control panels or rooftop HVAC systems.
• The Mersen ATDR20 is UL Listed to Standard 248-4 (Class CC) and CSA Certified to Standard C22.2. Its ability to provide superior branch circuit protection makes it a primary choice for engineers looking to comply with NEC and CEC safety requirements in automation, lighting, and machinery applications.
