Overview

The Mersen SAG6-1/4 plug fuse (SKU: SAG6-1/4) is a high-performance time-delay fuse designed for industrial and residential electrical systems requiring precise overcurrent protection. This 6.25A fuse operates at 1500V and features a ceramic body with a low melting-point temperature element, ensuring rapid response to overloads while accommodating normal surge currents typical in motor and cyclical load circuits. The SAG series is CSA-certified for Canadian applications, with Type 'P' fuses recommended for non-motor loads and Type 'D' fuses for electrical heating and cycling loads. Both fuse types have low melting-point temperature elements. Type 'S' plug fuses are time-delay and tamper resistant. The fuse dimensions are 1/4" x 1-1/4", making it compatible with standard Edison base sockets. With a 10kA interrupting rating (I.R.) and UL/CSA Listed certification, the SAG6-1/4 provides reliable protection for receptacle, lighting, and motor circuits. Its time-delay design allows brief overloads without nuisance tripping, while the tamper-resistant Type 'S' configuration prevents unauthorized ampere substitutions. Non time-delay fuses are available for receptacle and lighting circuits and time-delay fuses for motor loads. Ideal for demanding environments where safety and performance are critical, this fuse meets stringent North American electrical standards.

Littelfuse Plug fuses provide overcurrent protection to general purpose circuits and small motor loads. Edison-base Plug fuses (TOO and TLO series) feature metal threads similar to incandescent lamp bases. Type S Plug fuses (SOO and SLO series) utilize a nonmetallic threaded base and must be used with Type S adapters (SAO series). The National Electrical Code permits Edison base Plug fuses to be used for replacement purposes only. Type S fuses and adapters prevent shunting open fuses and over-fusing.
