SBF 250 connector 561171

Power connector for DIN rails

The SBF 250 connector is an indispensable element in electrical installations, designed for safe and efficient connection of power cables on a DIN rail. Its design allows for connecting both round and flat cables, making it an extremely versatile solution. Made of tinned copper, it enables the connection of copper and aluminum wires, eliminating the need for additional adapters. The transparent housing facilitates visual inspection of the connection, ensuring proper installation.

Design and application

The SBF 250 connector has been designed for demanding applications. High filling factor (over 95%) and solid construction guarantee reliability even under high loads. The tilting and removable mounting cover for the screw facilitates access and provides convenience during installation and maintenance. The modular design allows for creating multi-pole power supply blocks, tailored to individual needs. The connector is used for connecting output/input devices, connections between main and secondary switchboards, and as a main input/output connection to industrial machines and equipment (e.g., inverters, air conditioners).
