Cylindrical Fuse(RT14)

Product Description

These fuse are supporters for fuses with size up to 22*58mm. They are capable of working under heat caused by rated current and expected short impacting current up to 100KA. It can also function as a fuse disconnecting switch by multi-phase combination. There are two in/out lines at the RT18N fuse base, providing a power cut function. The RT 18L type has a safety lock to lock the fuse carrier when disconnected to avoid wrong operation; It can also be equipped with an indicator, which goes on when the fuse links breaks.

Rated insulate voltage up to 690V, Working frequency 50Hz AC. Conventional free air thermal current up to 125A, Compliant with GB13539.1, GB13539.2, GB13539.6, GB14048.3 and IEC269-1, IEC269-2, IEC 269-2-1, IEC947-3

RT14 SERIES FUSE

Application

RT14 type cylinder cap fuse can be applied in power distribution devices with rated voltage up to AC 380V, and rated current up to 63A to protect the devices from overload and short-circuit. The combining using of impinger-installed fuse and fuse type isolator can be used for motor’s open-phase protection means.
