1sna167090r2100 – fu 103 accompagn, 6a

Why Choose the TE Connectivity 1SNA167090R2100 FU103 6A Motor Fuse?

The TE Connectivity 1SNA167090R2100, also identified as FU103 6A and FU103-6A-SB, is a specialised 10.3 × 38 mm cylindrical motor fuse from the TE Connectivity / Entrelec SNA Series accessory range. Rated at 6 A, it is designed for compatible fused terminal blocks used in industrial control, motor and electrical distribution applications.

This FU103 variant is the slow / aM motor-circuit type, providing characteristics suited to circuits where short-duration starting currents need to be tolerated while maintaining fuse protection against higher fault currents. Its cylindrical 10.3 × 38 mm format allows installation in specified Entrelec fuse terminal blocks including the MB10/22.SF, MB10/22.SN, MB10/24.SF and MB25/30.SF.

With a rated current of 6 A and an approximate net weight of 10 g, the 1SNA167090R2100 provides a compact replacement fuse for compatible Entrelec assemblies. It is supplied in manufacturer packs of 10 and is intended for use with fuse terminal block installations on common G32 and TH35 DIN rail systems.

FU103 Slow-Acting Motor Circuit Protection

The FU103 1SNA167090R2100 is an aM-type motor fuse, making it suitable for compatible motor circuits where temporary starting currents are expected. The time-delay characteristic helps prevent unnecessary fuse operation during normal motor starting conditions while providing protection against higher fault currents as part of a correctly coordinated motor protection system.

Its 10.3 × 38 mm cylindrical construction is designed for specified Entrelec fuse terminal blocks, allowing the fuse to be integrated into modular control panel assemblies. When replacement is required, the defined 6 A rating and FU103 format make correct component identification straightforward for maintenance and panel service work.

Typical Applications

• Motor control circuits.
• Industrial fuse terminal block assemblies.
• Machine control panels.
• Automation and process control equipment.
• Switchgear and electrical distribution panels.
• Maintenance and replacement of compatible Entrelec fused circuits.
