5 x 20mm Fast-acting Glass Tube Fuses
GMA Series
Description
• Fast-acting, low breaking capacity
• Optional axial leads available
• 5 x 20mm physical size
• Glass tube, silver-plated (63mA-315mA) and nickel-
• Designed to UL/CSA 248-14
* Interrupting ratings: Interrupting ratings for 63mA - 6A were measured at 70% - 80% power factor on AC. The interrupting ratings for 7A - 15A were measured at 100% power factor on AC.
** DC Cold Resistance (Measured at <10% of rated current)
† Typical Pre-Arching I
