Briefly Describe Through-wall Terminal Blocks And Fuse Terminal Blocks
Through-wall terminal blocks:
The wall-through terminal uses screw connection technology, the insulation material is PA66 (flame retardant grade: UL94, V-0), and the connector uses high-quality, highly conductive metal materials. H-type through-wall terminal blocks can be installed side by side on panels of 1mm to 10mm thickness, and can automatically compensate and adjust the distance of panel thickness to form a terminal block with any number of poles, and can use isolation plates to increase air gap and creepage distance.
The wall-through terminal can be firmly installed in the rectangular reserved hole on the panel without any tools, and the installation is extremely convenient. H-type wall-through terminal blocks are widely used in some occasions that require wall-through solutions: power supplies, filters, electrical control cabinets and other electronic equipment. The insulation performance is good, the protection level is high, the user only needs to work directly after the external wiring, eliminating many unnecessary wiring steps.
Related knowledge of fuse terminal:
The insulating material will be modified nylon (PA66). In this regard, it will also have good electrical and mechanical properties. The screw is made of high-strength copper alloy, the conductor is made of electrolytic copper, and the wire frame is made of alloy copper that resists stress crack corrosion. The surface of these metals is also plated with tin or nickel for protection. All-copper terminals can avoid the battery effect of steel metal parts and copper wires in a humid environment.
There must be a connection hole in the middle of the fuse terminal, which can be connected in the center or with a side plug-in connector; it can be connected to electrical products with a 4mm2 conductor voltage of 800V and a current of 41A.
Knowledge of the test terminal:
The sliding metal piece that functions as a switch can withstand larger working currents through the test terminal crimping frame. When switching, use a screwdriver to loosen the screw, move the slider row, and the switch position is clear; both ends are equipped with test sockets for matching The corresponding test test terminal can be connected to test, and the operation can be uninterrupted when measuring current. It can be connected to a control loop with a voltage of 660V and a current of 57A.
