Phoenix Contact 3208943 Fuse Modular Terminal Block

The PHOENIX CONTACT PT 4-FSI/F fuse modular terminal block is designed for secure and efficient power distribution in industrial applications. Its push-in connection simplifies wiring, while the compact design allows for space-saving installations. The terminal block supports conductors from 0.2 mm² to 6 mm² and is rated for a nominal current of 10 A and a nominal voltage of 400 V. It is mounted on NS 35/7.5 or NS 35/15 rails and offers a testing facility for easy verification of connections. This terminal block is ideal for use in control cabinets, power supplies, and other electrical systems where reliable and compact fuse protection is required.
