Cabinet real estate presents continuous challenges in industrial automation panels and power distribution enclosures. Implementing Multi-level Terminal Blocks allows control cabinets to double connection density on a standard DIN rail without expanding physical enclosure dimensions. Hangda Electric manufactures the JHD5-2.5C Double-Level Terminal Block, delivering compact, organized wire termination for modern control systems.
Space Optimization in High-Density Panels
Stacking feed-through levels vertically cuts required mounting width in half. Modern multi level terminal blocks isolate signal and power lines within stacked tiers, eliminating wire clutter inside switchgear.
-
Footprint reduction: Doubles wiring capacity across a single 5.2 mm width.
-
Vibration resistance: Clamping components maintain contact pressure to prevent conductor loosening.
-
Touch protection: Recessed terminals safeguard operators against accidental shock.

Practical Application Advantages
Streamlined Circuit Segregation
Each multi level terminal provides independent feed-through circuits across two tiers. Dedicated jumper slots permit flexible potential distribution across adjacent units, accelerating field wiring routines.
-
Rapid identification: Marking tags clarify circuit tracing during maintenance cycles.
-
Efficient bridging: Plug-in jumpers link identical potentials without auxiliary jumpers.
