They are ideal for space‑saving and ease of maintenance fuse solutions. Fuse types Type C and F flat‑type fuses distinguishes them from the fuse terminal blocks. In addition, the type of fuse is different. Fuse types Midget fuses, glass/ceramic Plug-in fuse terminal blocks Function FSI/C and FSI/F plug‑in fuse terminal blocks are used to safely accommodate flat‑type fuses for protecting electrical circuits. The plug‑in mechanism enables the fuses to be inserted and removed without tools. Characteristics A central feature is the integrated plug‑in zone for flat‑type fuses in accordance with ISO/DIS 8820/DIN 72581‑3, which enables easy insertion and removal of the fuse and ensures secure fixing and good contact quality. Fuse holders Function A fuse holder is used to safely hold and electrically contact a fuse within a circuit. It enables reliable protection against overcurrent by mechanically fixing the fuse and at the same time enabling it to be replaced safely once tripped. Differentiation from fuse terminal blocks In contrast to the fuse terminal blocks, the primary task of the fuse holder is to hold the fuse. Although they also have two connection points, they do not have additional bridge shafts for potential distribution, which essentially PT 6-FSI/C plug-in fuse terminal block PT 10,3-HESI 1000V fuse holder Diode terminal blocks Function Diode terminal blocks are special component terminal blocks that contain one or more diodes. These only allow the current to flow in one direction and block it in the opposite direction, which is ideal for protecting against reverse currents and preventing damage to sensitive components. Characteristics The diode terminal blocks are characterized by one or more integrated diodes. These diodes ensure reliable current direction control. Versions with 44 Phoenix Contact LEDs and varistors are also available and offer additional functions such as status displays and surge protection. Application Diode terminal blocks are used in control and automation systems, especially where reverse currents are to be avoided and operational safety increased. They are also suitable for DC grids and are often used in control cabinet solutions. PT 4-DIO 1N 5408/L-R diode terminal block

Fuse terminal blocks and component terminal blocks Component terminal blocks Function Diode terminal blocks contain one or more diodes that are integrated into the circuit. These diodes only allow the current to flow in one direction and block it in the opposite direction. This protects against reverse currents and prevents damage to sensitive components. Characteristics • Integrated diodes: The diodes are permanently integrated into the terminal block and ensure reliable current direction control • Direction‑dependent current flow: Allows current to flow in one direction only and blocks it in the opposite direction Application These terminal blocks are particularly useful for preventing reverse currents and increasing the reliability of electrical circuits.
