FAQs
TPM-12 is designed for standard telecom protection in racks and enclosures. It operates at 80 Vdc, supports up to 12 A, and offers a 20 kAIC interrupt rating. The device uses a non-indicating, miniature format that fits neatly into typical cabinet spaces and is compatible with the Eaton Bussmann TPM series for easy part replacement and stock management.
Key specs include an 80 Vdc voltage rating, 12 A current rating, and a 20 kAIC interrupt rating, with current-limiting protection. These features enable rapid fault clearance, minimize fault energy, and protect sensitive telecom circuitry such as line cards, protectors, and data-path interconnects in network equipment.
Yes. TPM-12 is well-suited for data center telecom deployments where space is at a premium and reliable protection is essential. Its 80 Vdc operating rating, 12 A capacity, and 20 kAIC interrupt capability, combined with a non-indicating, compact form factor, provide robust overcurrent protection for critical network devices and interfaces.
TPM-12 carries CE Marking, indicating compliance with European safety and performance standards. This certification supports regulatory acceptance for European missions and cross-border telecom deployments, helping manufacturers and integrators meet regional requirements during commissioning and auditing.
TPM-12 reduces downtime by delivering fast fault clearing and reducing downstream damage to telecom equipment. Its non-indicating design lowers maintenance checks in dense cabinets, and its compatibility with the TPM lineup simplifies stocking and replacements, enabling faster repairs and fewer service delays in field deployments.
