FAQs
The TTM450 is designed to fit standard BS88 low-voltage fuse applications and conforms to IEC 60269 performance classes gL/gG, ensuring straightforward substitution in compatible BS88 holders. Check that the physical form factor (approximately 74 x 210 mm) matches your enclosure’s fuse space, and confirm mounting or center-bolted arrangements as per your panel design. This minimizes field modifications and reduces commissioning time.
The TTM450 is rated for 450 A with AC operation up to 660 V and DC operation up to 450 V. Its gL/gG characteristics suit main feeders and motor protection in industrial distribution, making it ideal for switchgear assemblies, panel boards, and large control centers where reliable interruption and clear fault isolation are required.
Industries with heavy electrical loads and strict compliance needs benefit most, including manufacturing, chemical processing, and water treatment plants. It also suits infrastructure projects and facility power distribution where BS88, CE, RoHS, and IEC 60269 compliance streamline approvals and maintain uptime in critical services.
The TTM450 carries CE marking, RoHS compliance, and BS88 IEC 60269, plus KEMA and EAC certifications. These attest to safety, environmental standards, and regional acceptability, easing cross-border procurement and reducing qualification time for regulated projects.
