Information About AJT150

The AJT150 is part of the Mersen Amp-Trap 2000® AJT Series, offering time-delay circuit protection up to 600 V AC and 500 V DC. With a SmartSpot® indicator for quick identification of blown fuses, the AJT150 ensures maximum uptime and faster maintenance. Its dual-element design handles inrush currents while limiting let-through energy, making it suitable for motor loads, transformers, and other inductive circuits. Built with a melamine fiberglass-reinforced body and tin-plated copper terminals, it meets UL, CSA, and IEC standards and is compatible with non-rejection Class J fuse blocks such as JFB, SJ, US3J, and US5

Key Features:

  • Time-Delay Performance: Designed to manage temporary inrush without nuisance tripping.
  • SmartSpot® Indication: Visual fuse status indicator improves maintenance efficiency.
  • Dual-Element Construction: Supports both short-circuit and overload protection.
  • High Interrupt Ratings: Rated 200kA at 600V AC and 100kA at 500V DC for robust fault handling.
  • Compact Blade Design: 5-3/4" length requires less panel space compared to Class RK fuses.
  • Melamine Body Material: Offers high thermal and dimensional stability under harsh conditions.
  • Hazardous Location Compatibility: Suitable for use in NEC Class I Div. 2 environments.
  • Arc Flash Reduction: Recommended for systems requiring minimized arc energy exposure.
  • Permanent Traceability: Metal-embossed date and catalog marking for lifecycle management.
  • Easy Selectivity Coordination: Supports 2:1 ratio for preventing upstream fuse tripping.

The AJT150 offers rugged time-delay performance, fast fault clearing, and easy blown fuse identification for industrial circuit protection.
