Description

The Cylindrical Fuse Holders are designed for reliable performance in electrical systems, rated for an insulated voltage of up to 690V and operating at a frequency of 50Hz AC. With a conventional free air thermal current capacity of up to 125A, these fuse holders comply with GB13539.1, GB/T13539.2, and IEC60269-1 and IEC60269-2 standards. They support fuses sized up to 22x58mm and can effectively manage the heat generated during operation.

These holders also function as fuse disconnecting switches in multi-phase combinations. The RT18N model features two in/out lines, enabling a power cut function, while the RT18L model includes a safety lock to prevent incorrect operation when the fuse carrier is disconnected. An optional indicator light alerts users when the fuse link is broken, enhancing safety and operational efficiency.

Additional Information

The Cylindrical Fuse Holders are engineered with a plastic-injected case that houses contacts and fuse links. The bases are either welded or riveted, ensuring durability and multi-phase structural capability. Models such as FB15C, FB16-3J, FB19C-3J, and RT19 offer open-structure designs, while others are semi-concealed. The RT18 series bases can be installed on DIN rails, with the RT18L model providing an added safety lock feature during disconnection.
