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.
