FAQs
Install the TPS-25 using ferrule-end terminations on both sides, using appropriate crimp tools to ensure a solid, low-resistance connection. Verify the device is rated for 170 Vdc and that wiring follows the device’s 0.56 in depth and 0.56 in width footprint. Always consult the Eaton datasheet for torque specifications and enclosure clearance.
The TPS-25 provides a 25 A amperage rating, 170 Vdc voltage rating, and a 100 kAIC (kiloampere interrupting capacity) interrupt rating, enabling rapid fault clearing while protecting downstream equipment in telecom and data-center power paths.
Yes. With current-limiting performance and ferrule-to-ferrule connections, the TPS-25 is well-suited for telecom power distribution, network equipment protection, and edge computing deployments where reliable overcurrent protection and fast interruption are essential.
TPS-25 is CE marked and RoHS compliant, ensuring conformity with European regulatory requirements and restriction of hazardous substances. These certifications support global deployments while aligning with procurement and compliance standards.
Because it is non-indicating, status monitoring relies on external diagnostics or powered test procedures, reducing panel clutter and maintenance complexity. Its high interrupt rating and robust ferrule construction help extend service life in demanding environments, lowering replacement frequency and total cost of ownership.
