Overview
The Bussmann FNQ-R-2 is a Class CC time-delay, dual-element current limiting fuse engineered for industrial control circuits and transformer protection. Rated 2A at 600V with a 200 kA interrupt capacity, rejection type, dual-element melamine construction, this fuse combines rapid short-circuit response with inrush tolerance for equipment compatibility.
Key Features
- Time-delay design with 12-second response at 200% current for compatibility with inrush loads like small control transformers
- Current-limiting performance providing 10X faster short-circuit protection than standard circuit breakers, UL and CSA listed
- Rejection-style cartridge body fits both standard and rejection-type holders with ferrule terminals
- Compact 13/32″ diameter × 1-1/2″ length cylindrical design for space-constrained panels
- Non-indicating fuse; status determined by visual cartridge inspection
- Meets UL 248-4 and CSA standards; CE approved
Technical Specifications
The FNQ-R-2 is a Bussmann Limitron Class CC fuse with a current rating of 2A, voltage rating of 600V, and 200kA interrupting rating. The cartridge features a dual-element melamine tube body measuring 13/32 in diameter by 1-1/2 in length with ferrule end terminals. This design supports rejection-type fuse holders and clip termination.
