Mersen AJT17-1/2 Amp-Trap 2000 Time-Delay Class J Fuse 17.5A 600V SmartSpot Indicator

Description

Features

• The Mersen AJT17-1/2 features advanced SmartSpot technology.
• Engineered to standard Class J dimensions (13/16-inch diameter by 2-1/4-inch length), this 17.5-amp cylindrical cartridge fuse explicitly enforces a physical rejection feature that prevents dangerous installation errors with other fuse types. It drops directly into any standard low-voltage Class J fuse block, making it a drop-in replacement for older configurations or upgrades in tight control centers.
• Built with dual-element, time-delay characteristics, this current-limiting power fuse safely absorbs harmless transient surges and momentary starting inrush currents from motors and transformers.
• Boasting an exceptional 200 kA interrupting rating (AIC) at 600 VAC, this Amp-Trap 2000 series fuse delivers superior current limitation by lowering peak let-through energy. It is actively recommended for facility arc flash energy reduction, keeping your maintenance crew safer and satisfying strict industrial safety compliance codes.
• The body is constructed from premium fiberglass-reinforced GMG (glass melamine) material filled with high-grade silica sand for rapid arc quenching. This resilient design guarantees structural stability and prevents arc tracking in high-vibration manufacturing plants, industrial processing facilities, and HVAC control panels.
• Featuring an engineered 2-to-1 coordination selectivity ratio, this Class J fuse simplifies system design by isolating faults strictly to the affected branch circuit.
