GMA-3.15A Description

Short technical summary and product information.

The Eaton GMA-3.15A is a fast-acting glass tube fuse designed for overcurrent protection. It is rated for 3.15A at 125V AC and offers a breaking capacity of 10kA at 125V (measured at 70-80% power factor). The fuse features a typical melting I²t of 9.7 A²s, a DC cold resistance of 0.036 Ω, and a maximum voltage drop of 210 mV at rated current.

 

Constructed with a glass tube and nickel-plated brass endcaps, the fuse is housed in a 5mm x 20mm cartridge package. It requires a holder for mounting and is available in packaging codes BK, BK1, and TR2. The GMA series is designed to UL/CSA 248-14 standards and carries UL and CSA approvals.

 

This fuse is suitable for a wide range of general-purpose circuit protection applications where fast-acting characteristics are required. Its compact size and reliable performance make it a common choice for power supplies, appliances, and industrial control circuits.
