1sna167091r1600 – fu 103 accompagn, 8a

Why Choose the TE Connectivity 1SNA167091R1600 FU103 8A Motor Fuse?

The TE Connectivity 1SNA167091R1600, also identified as FU103-8A-SB, is a specialised 8 A slow-acting cylindrical motor fuse from the TE Connectivity / Entrelec terminal block accessory range. Manufactured in the standard 10.3 × 38 mm format, it is designed for compatible fused terminal block assemblies used in industrial motor control and electrical protection applications.

This FU103 variant uses a SLOW / aM characteristic, making it suitable for motor circuits where temporary starting currents must be tolerated without unnecessary fuse operation. The aM operating characteristic is intended for motor-circuit applications and provides short-circuit protection when correctly coordinated with appropriate overload protection.

Rated at 8 A and 500 V, the 1SNA167091R1600 provides a compact replacement fuse for compatible Entrelec installations. It is supplied in manufacturer packs of 10, providing a convenient option for panel builders, maintenance teams and industrial users servicing multiple fused circuits.

Slow-Acting Protection for Motor Circuits

Electric motors can draw significantly more current during starting than during normal operation. A slow-acting motor fuse is designed to tolerate these expected short-duration current peaks while remaining available to interrupt higher fault currents. The FU103 1SNA167091R1600 provides this functionality through its aM motor fuse characteristic.

The compact 10.3 × 38 mm cylindrical format makes the FU103 suitable for compatible fused terminal block and fuse-holder installations. When combined with appropriate overload protection and correctly rated system components, the 8 A FU103 provides a practical fuse solution for motor control panels, machinery and industrial electrical distribution equipment.

Typical Applications

• Industrial motor control circuits.
• Motor starter and control panels.
• Machine electrical systems.
• Automation and process control equipment.
• Compatible fused terminal block assemblies.
• Industrial switchgear and electrical distribution panels.
