Hangda Electric manufactures Disconnect & Test Terminal Blocks designed for control cabinet space optimization. The dual-tier architecture integrates an upper disconnect path with a lower feed-through circuit, cutting rail space requirements in half. Each fuse holder terminal incorporates a PA66 flame-retardant housing to resist high temperatures and mechanical shock during demanding operations.
Compact Rail Architecture and Circuit Testing
-
Dual-tier footprint: Two distinct electrical paths occupy the rail width of a single standard unit.
-
Direct isolation: The integrated knife lever enables circuit interruption without removing conductor wires.
-
Test plug sockets: Standard test points allow rapid multimeter diagnostics directly on the terminal.
Equipping control systems with a double level fuse terminal block eliminates wiring clutter across crowded enclosures. Hangda Electric ensures reliable DIN rail mounting through precision steel clamping yokes that prevent loose connections under severe vibration.
High-Performance Protection for Industrial Power
DC Circuit Isolation and Fault Handling
A dedicated dc fuse terminal block provides selective branch protection against transient voltage spikes and sustained overcurrent conditions. The screw-clamp connection accommodates both solid and stranded conductors, maintaining low contact resistance across continuous duty cycles.
Modular Flexibility and Maintenance
-
Individual branch isolation: Disconnect specific field circuits while adjacent lines remain fully powered.
-
Tool-free fuse inspection: The pivoting carrier provides clear visual status and rapid cartridge replacement.
Integrating a fuse modular terminal block streamlines panel assembly while simplifying field maintenance schedules.
