FAQs
TP15900-4 is designed for modular DC protection and is intended for use with TPA Series fuses. It features a four-pole, rear-access configuration with a 1 inch depth, 2 inches width, and 0.5 inch height, weighing 0.034 lb. It fits standard control panels, supports 145 Vdc and 80 Vdc circuits, and enables quick substitution during upgrades with minimal wiring changes.
The device provides 40A at 145 Vdc and 50A at 80 Vdc, with voltage ratings of 145 Vdc and 80 Vdc. It is a four-pole, fusible disconnect switch designed for DC protection. The compact form factor supports rear-access wiring, and it is compatible with Bussmann TPA fuses to enable reliable, replaceable protection in compact panels.
Yes. TP15900-4 is specifically rated for 145 Vdc operation with 40A (and 50A at 80 Vdc), making it suitable for DC distribution in automation, control cabinets, and battery interfaces. Designers should ensure the fuse type and panel ratings align with the device’s 145 Vdc/max current capability and follow proper safety procedures during installation.
TP15900-4 carries CE Marking and RoHS compliance, indicating conformance with essential safety directives and environmental standards. This supports regulatory compliance in many markets and helps ensure that installations meet industry expectations for electrical protection devices used in automated systems.
Rear-access wiring simplifies installation and maintenance by allowing connections from the back of the panel, reducing side clearance and enabling neater layouts. This lowers installation time, minimizes panel disruption during service, and shortens downtime, contributing to a lower total cost of ownership and faster return on investment in automated environments.
