Industrial FNQ-15-100 Time Delay Fuse

Description:

The TRON FNQ-15 Time Delay Fuse is used in electrical protection systems for providing supplemental overcurrent protection in control circuits, transformers, relays, and industrial equipment. Commonly installed in motor control panels, electrical cabinets, HVAC systems, and power distribution equipment requiring protection against overloads while allowing temporary inrush currents. Maintenance teams and electricians use this part for fuse replacement, electrical repairs, preventative maintenance, and restoration of protected circuits.

Applications:

The TRON FNQ-15 Time Delay Fuse is commonly used in industrial electrical applications including control transformers, relay circuits, instrumentation panels, lighting systems, and motor control equipment where reliable circuit protection and tolerance of startup current surges are essential. The FNQ series is designed as a time-delay midget fuse for circuits with inrush current conditions.
