630A current rating protects high-energy feeders and main circuits; this translates to measurable downtime reduction and equipment longevity in switchgear applications. Engineers can select this fuse with confidence for UK BS88-standard installations, knowing it fits British-standard carriers and harmonizes with existing protection schemes across plants. AC voltage rating of 660V and DC rating of 450V broadens application across mixed-supply environments; this flexibility reduces the need for multiple fuse types in a single panel, streamlining procurement and spare-part logistics. The gL/gG fuse type delivers high breaking capacity for general protection and short-circuit scenarios; invaluable for feeders, motors, and distribution circuits where reliable interruption is critical. Compact 74 x 210 mm footprint with a 75 mm width and 1082 g weight fits standard fuse carriers and retrofit projects; installers benefit from predictable handling and minimal alteration to panel enclosures. Regulatory compliance is built in with CE marking, RoHS, BS88 IEC 60269 and EAC certifications; this accelerates multi-region deployments and reduces compliance risk. Additional value comes from documentation and availability, including Eaton catalog CA134002EN and UKCA declarations; engineers can reference datasheets and declarations for in-spec procurement.

FAQs
The TTM630 is designed for standard British BS88 fuse carriers and fits the 74x210 mm form factor typical of BS88 British Standard protection devices. When selecting a carrier, verify it supports the 630 A rating, the gL/gG type, and the 75 mm width/height to ensure proper alignment and secure mounting. This compatibility minimizes retrofit efforts and accelerates panel upgrades.
The fuse is rated for 630 A with AC voltage up to 660 V and DC voltage up to 450 V, making it suitable for main feeders, distribution boards, and motor circuits in industrial environments. This versatility supports mixed-voltage panels and simplifies protection schemes, reducing the need for multiple fuse types in a single installation.
Yes. The TTM630 carries CE marking and RoHS compliance, along with BS88 IEC 60269 and EAC certifications. This ensures global regulatory alignment, enabling safer export and multi-region deployment while meeting UK and international protection standards.
To minimize downtime, stock standard BS88-compatible fuses like TTM630 for common panels, label clearly, and maintain documentation such as the CA134002EN catalog and declarations. Verify the carrier compatibility, ensure correct torque values where applicable, and keep spare units on hand for rapid replacement to reduce production impact during faults.
The TTM630 supports longer replacement intervals and standardized procurement across regions, reducing spares variety and stocking costs. Its BS88 compliance and robust discharge characteristics help lower nuisance trips and maintenance overhead, while the common form factor and availability from Eaton streamline procurement and support, delivering predictable total cost of ownership in multi-site facilities.
