Why Choose the TE Connectivity 1SNA168560R1500 FU633 6.3A Cartridge Fuse?
The TE Connectivity 1SNA168560R1500, also identified as FU633-6.3A, is a 6.3 A fast-acting cylindrical glass cartridge fuse from the Entrelec SNA terminal block accessory range. It is designed to provide replaceable overcurrent protection in compatible fused terminal blocks and electrical fuse holders used in industrial control and distribution systems.
The FU633 has a compact 6.3 × 32 mm cylindrical format, corresponding closely to the nominal 6.3 × 31.5 mm description used for this product. Its fast (F) operating characteristic enables prompt interruption when excessive current occurs, helping protect connected wiring and equipment.
Designed for compatibility with selected Entrelec fused terminal blocks including M10/16.SF, ML10/13.SF, MU10/13.SF and MU10/14.5.SF, the 1SNA168560R1500 weighs approximately 2 g and is supplied in a factory pack quantity of 10. It is a practical replacement fuse for maintaining established SNA terminal installations.

Fast-Acting Protection for Fused Terminal Circuits
Fast-acting cartridge fuses are intended to interrupt excessive current rapidly before prolonged overcurrent can damage compatible wiring or equipment. The FU633-6.3A provides this protection in a compact replaceable format suitable for selected industrial fused terminal blocks.
When a fuse operates, the underlying electrical fault should be identified and corrected before the cartridge is replaced with a fuse of the correct type and rating. The removable FU633 format supports efficient maintenance of control panels, machine systems and other industrial electrical assemblies.
Typical Applications
- Compatible Entrelec SNA fused terminal blocks.
- Industrial control and automation panels.
- Instrumentation and measurement circuits.
- Machine control equipment.
- Switchgear and electrical distribution assemblies.
- 6.3 A fast-acting overcurrent protection in compatible fuse holders.
