For installation, insert the fuse into a compatible holder until it seats firmly, ensuring the electrical contacts align with the busbar and the fuse carrier. Verify polarity isn’t a factor for these non-polarized devices and replace only with the same current rating to preserve protection integrity.
The TC100M125 is rated at 125 A with AC voltage up to 660 V and DC voltage up to 350 V. It is suitable for industrial power distribution, electrical panels, and feeder circuits where overcurrent protection is required for both AC and DC service conditions, including control panels and motor feeder lines. Use within the BS88 fuse family to ensure interchangeability with compatible enclosures.
Yes. The TC100M125 carries IEC Rated certification and is built to align with the BS88 British Standard fuse family, enabling standardized protection across international and UK-based installations. This compatibility supports regulatory compliance, simplifies audits, and ensures consistent protection performance in industrial environments.
UK regulatory declarations related to this product include UKCA declarations for fuse-link variants. Eaton provides declarations of conformity in the product downloads area, such as UKCA Redspot fuse-links PDFs. These documents help verify regulatory compliance for UK installations and support procurement with formal conformity evidence.
The TC100M125 delivers reliable protection with a defined 125 A rating, potentially reducing unexpected outages and equipment damage. In practice, maintenance involves periodic inspection of fuses in service, replacement with identical current rating and voltage specifications, and monitoring for signs of contact resistance. The standardized BS88 form factor and IEC Rated certification help simplify stocking and spare-part costs, contributing to lower total cost of ownership over time.
