Eaton Specification Sheet - TP15900-41-2
The four-pole design provides complete isolation of each DC conductor, enabling safer servicing and quicker fault diagnosis. By preventing cross-conduction during maintenance, it reduces the risk of arc flash and equipment damage. This is essential for DC distribution modules in energy storage systems and motor-drive assemblies. Rear-access operation allows wiring and fuse changes without removing the switch from the panel; this minimizes downtime and speeds preventive maintenance. Operators benefit from safer, easier access to connections, while technicians appreciate standardized rear-entry installation benefits. High-current ratings of 40 A at 145 Vdc and 50 A at 80 Vdc support common DC power architectures, including medium-scale drives and distributed power rails. The 145 Vdc and 80 Vdc ratings align with many industrial DC networks, enabling flexible protection schemes. Compact footprint (4.78 in L x 4.1 in H x 1.55 in W) fits tight panel cavities and reduces enclosure depth, while the lightweight profile (0.67 lb) simplifies handling during installation and retrofits. CE Mark and RoHS compliance ensure regulatory alignment across global markets, while the 140 °C operating temperature withstands demanding environments, reducing maintenance risk. The TP15900-41-2 integrates with Eaton Bussmann series fuses for consistent protection and quicker spare-part sourcing, helping standardize inventories across multiple panels.

FAQs
When installing TP15900-41-2, ensure adequate rear-access clearance for wiring and fuse replacement. The unit's footprint (4.78 in L x 4.1 in H x 1.55 in W) fits compact panel cavities, while its four-pole design requires space to isolate each DC conductor. Verify 145 Vdc and 80 Vdc ratings align with your DC network, and plan for a 0.67 lb module within the panel’s mounting structure.
The device provides 40 A at 145 Vdc and 50 A at 80 Vdc, with voltage ratings of 145 Vdc and 80 Vdc. These ratings guide protection sizing, conductor sizing, and fuse coordination in DC power rails. Use this switch where full isolation and reliable interruption of mid-range DC currents are required, such as energy storage and motor-drive circuits.
Yes. The unit is rated for up to 140 °C operating conditions, making it suitable for hot industrial environments and challenging DC power applications including energy storage systems. Its rear-access design also reduces heat buildup in tight enclosures by enabling efficient cooling and straightforward maintenance in high-temperature facilities.
The TP15900-41-2 is CE Marked and RoHS compliant, ensuring it meets European safety, health, and environmental requirements. This combination helps manufacturers satisfy global regulatory obligations, supports safer integration into European-international projects, and reduces risk during audits or inspections.
The four-pole isolation reduces maintenance downtime and accelerates safe servicing, while rear-access design shortens fuse replacement times. Combined with compact form factor and high-temperature tolerance, the device lowers enclosure redesign costs, minimizes spare parts inventory, and improves system uptime—delivering lower operating costs and faster project timelines over the equipment lifecycle.
