What is a Busbar Connector?
Busbar Connectors are used to safely connect two or more busbars to ensure stable current transmission.
Consider the following when choosing a suitable Busbar Connector:
● Conductive material – choose copper bus bar connectors to ensure optimal conductivity
● Load capacity – select busbar terminal connector specifications based on current requirements
● Installation method – ensure that the bus bar connector strip is compatible with your busbar system
A: Compatible with standard 5mm-25mm busbar thickness, custom specifications are supported.
A: Yes, our busbar terminal connector can support up to 5000A current.
Simply clip the module onto standard DIN rails inside your panel—no extra brackets needed. Then align phases and tighten screws for a secure electrical connection.
An IP-rated module (e.g., IP54+) protects against dust and water ingress, ensuring safe, reliable power distribution in harsh outdoor or wash‑down environments.
Built‑in fuse holders allow fast overcurrent protection and simpler maintenance—swap fuses without rewiring or disassembling the busbar system.
A 250 A-rated module is ideal for main feeders in industrial control panels, main distribution boards, and large motor starters requiring robust, low‑loss power transfer.
Modular systems let you snap together sections, maintain consistent phase spacing, and expand capacity easily—reducing wiring errors and installation time.
Selection & support
Match busbar section, cable cross-section and rated current.
The range includes the LPSU3-E 3-pole module with spring terminals for 12×5 to 30×10 mm busbars and 1.5–16 mm² cables, the LP300A54 terminal plate for 20×5 to 30×10 mm busbars and 6–50 mm² cables at up to 300 A, and the LP440A81 for 35–120 mm² at up to 440 A. NH fuse holders LPA3600 to LPA3603 cover 160 A to 630 A on 60 mm busbar systems.
Check technical documentsUse a connection module or terminal plate sized for both the busbar section and the cable cross-section, and check its rated current against the load. Send the busbar size, cable size and current for a recommendation.
Ask for a recommendationCommon types are connection modules with spring or screw terminals, terminal plates for larger cables, busbar adapters that carry circuit breakers and other devices, busbar terminals that clamp a conductor onto the bar, and fuse holders that mount on the busbar system. Match each to the busbar section, cable size and current.
