Red GPO-3 fiberglass Sheet / Red polyester sheet / Red upgm203 / Red HM 2471 / Red GP0-3
Red GPO-3 fiberglass Sheet or related products are consists of non-alkali glass mat impregnated and boned with an unsaturated polyester resin ,and laminated under high temperature and press,GPO3 sheet offer a superior combination of electrical and mechanical properties such as dielect ric strength ,flame resistance,arc and track resistance,high-flexural and high-impact strength.
our laminates also have superior consistency in thickness, punchability and property control. Add a high degree of quality and cost-ffectiveness.
These sheets are fiberglass reinforced thermoset polyester,They will not melt under heat and have excellent overall electrical properties .all grades are UL Recognized.
Electrical Insulation :All grades of Red GPO-3 fiberglass Sheet have inherently good dielectrics. They are engineered to maximize the specific properties required for a wide range of electrical applications.
Flame Resistance :Red GPO-3 fiberglass Sheet are UL-rated V-0. They belongs to halogen-free system that generates very low smoke and smoke toxicity in a fire situation.
Mechanical Strength :Red GPO-3 fiberglass Sheet have stable mechanical strength wich won’t cracked when machining
Heat Resistance:Red GPO-3 fiberglass Sheet have excellent property retention and dimensional stability at elevated temperatures. These laminates have UL temperature index ratings over 150℃

GPO3 Used in the Molded case circuit breaker:
The molded case circuit breaker is also called a device breaker ,all parts are sealed in plastic shell, the touch head, arc-suppression , release devices and operating mechanism are assembled in a plastic casing through modularization.Generally, maintenance is not considered ,it suitable for branch protection switch ,overcurrent tripping device has two types: thermally magnetic and electronic.The arc-suppression plate in the structure is mainly used for the thin plate and the arc resistance HC-GPO3 ,arc-suppression plate acts as a protective effects.
