Eaton TMT355 British Standard Fuse - CE RoHS
Part Number: TMT355
Quick Summary
TMT355 is a low voltage British-standard fuse protecting electrical circuits in switchgear and control panels. This compact device is designed to simplify protective-coordination work, helping engineers prevent nuisance outages while staying within footprint constraints. The fuse delivers reliable overcurrent protection for AC circuits up to 660 V and 355 A, supporting fast site diagnostics when trips occur. It aligns with CE and RoHS compliance and carries BS88 certification, with UKCA declarations available for UK specifications. By combining a predictable form factor with straightforward installation in standard fuse holders, the TMT355 reduces design risk, supports regulatory adherence, and lowers total cost of ownership through longer service intervals and consistent performance in harsh industrial environments.

FAQs
TMT355 is designed to be compatible with standard BS88 fuse blocks used in European and UK control panels. Its 355 A current rating and 660 V AC voltage rating align with common industrial circuits, enabling straightforward substitution in existing installations and minimizing enclosure changes. It supports reliable protection without compromising space or serviceability.
TMT355 is manufactured to meet CE and RoHS requirements for European markets, ensuring restrictions on hazardous substances are respected. BS88 certification confirms conformity with British standards for low-voltage fuses. This combination simplifies procurement across EU/UK projects and supports traceability in compliance documentation and audits.
The fuse measures approximately 64 mm in depth, 64 mm in height, and 255 mm in width, with a weight around 785 g. These dimensions suit standard DIN-rail or cabinet-mounted fuse blocks in space-constrained panels. When selecting mounting hardware, verify enclosure clearance and ensure adequate airflow for thermal management during continuous operation.
Yes. TMT355 is specified for AC circuits up to 660 V and 355 A, making it appropriate for general protection of feeders, control circuits, and motor connections in industrial automation. Its gL/gG classification supports general-purpose protection, while the BS88 format ensures compatibility with British standard fuse links and common industrial apparati.
The 355 A/660 V rating provides reliable, predictable protection, reducing unplanned outages and downtime. BS88 compliance and CE RoHS support durable procurement and regulatory readiness, potentially lowering maintenance costs and administrative overhead. Documented performance and long service life contribute to improved total cost of ownership in new builds and retrofits.
