Protistor AR Cylindrical Fuses (10×38mm, 14×51mm, 22×58mm)
IEC Standard: 60269-4 (aR – Semiconductor Protection)
Key Features:
Ultra-fast acting (aR class) for safeguarding diodes, thyristors, and IGBTs.
DIN-size cylindrical bodies (10×38mm, 14×51mm, 22×58mm) for easy retrofitting.
High breaking capacity (up to 120kA) for industrial power electronics.
Applications: Solar inverters, motor drives, welding equipment.

Protistor GR Cylindrical Fuses (10×38mm, 14×51mm, 22×58mm, 27×60mm)
IEC Standard: 60269-2/4 (gR – Full-Range Motor Protection)
Key Features:
Dual-performance (gL/gR) for overload and short-circuit protection.
Time-delay design to withstand motor inrush currents.
Extended sizes (27×60mm) for higher current ratings.
Applications: Industrial motors, transformers, HVAC systems.

Global Compliance: UL 248, IEC 60269, CSA certified.
Durability: Ceramic bodies with precision sand-filling for arc suppression.
Interchangeability: Direct replacements for common DIN fuses (e.g., 10×38mm).
