Information About AJT200
The AJT200 is a member of the Mersen Amp-Trap 2000® AJT Series, designed to deliver reliable circuit protection with time-delay functionality. This fuse supports both AC and DC systems—rated at 600V AC and 500V DC—and is UL Listed and CSA Certified. Its cylindrical melamine body houses a dual-element design for handling motor starting surges and transformer inrush currents. Compatible with various fuse block series like JFB, SJ, US3J, and US5J, the AJT200 is engineered for quick identification with a SmartSpot® indicator and embossed catalog markings.
Key Features:
- Time-Delay Dual-Element Design: Handles temporary inrush current from motors and transformers without nuisance tripping.
- SmartSpot® Visual Indication: Provides clear fuse status at a glance to reduce troubleshooting time.
- High Interrupting Rating: 200kA at 600V AC and 100kA at 500V DC for enhanced circuit protection.
- Extremely Current Limiting: Minimizes let-through current, protecting downstream components.
- Class J Non-Rejection Fuse: Prevents incorrect fuse substitution through unique dimensions.
- Compact Cylindrical Body: Small footprint allows flexible installation and economical panel layouts.
- Global Standards Compliance: UL listed (UL248-8), CSA certified (C22.2 No. 248.8), and RoHS compliant.
- Reliable Connection Type: Ferrule-style tin-plated copper terminals ensure solid clip-mounted contact.
- Marine and Automotive Approval: Recognized by American Bureau of Shipping and meets key automotive specs.
- Wide Compatibility: Functionally equivalent to Bussmann LPJ and Littelfuse JTD series fuses.
The AJT200 delivers the reliability, current limitation, and clear fault indication required for mission-critical industrial and commercial electrical systems.
