Stud & Bolt Terminal Blocks

Robust, Reliable & Secure Connections

Stud & Bolt Series Terminal Blocks

Stud & Bolt Terminal Blocks are designed for heavy-duty power distribution, ensuring secure, vibration-resistant, and high-current connectivity in industrial and electrical applications. For making the connections the wire is crimped to a ring / fork lug and is screwed on to the flat current bar of the Terminal Block. These terminal blocks provide a strong mechanical connection using robust stud and bolt fastening, making them ideal for high-power circuits, busbar connections, and demanding electrical installations.

Engineered for maximum durability and efficiency, these terminal blocks can accommodate large cross-section conductors, ensuring low contact resistance and reliable electrical performance over extended periods. The bolted connection mechanism allows for tight and stable clamping, preventing loosening due to vibrations, thermal expansion, or mechanical stress.

CBB Series Busbar Terminal Blocks

CBB Series Terminal Blocks feature a busbar-type current bar design, providing a robust and reliable connection for high-current applications. Wires with lugs can be securely fastened to the flat surface of the current bar using a nut and bolt connection, ensuring a strong and stable electrical contact. These terminal blocks allow for the connection of two lugs of the rated cross-section without compromising safety or performance. Available in wire sizes ranging from 6mm² to 185mm².

Barrier Type Stud & Bolt Terminal Blocks

CSB & CBS Series

CBS & CSB Series Barrier-Type Terminal Blocks are designed for efficient wiring using both screwdrivers and nut drivers. These terminal blocks feature a marking provision on the top, allowing for easy circuit identification. Cross-connections between terminals can be made using screw-type (top-mounted), ring-type, and fork-type jumpers, providing flexibility in wiring configurations. For enhanced safety, protective covers that mount directly onto the terminal blocks are also available as additional accessories.

STH Series Stud & Bolt Terminal Blocks

Captive Nut Design with IP-20 Protection

STH Series Stud Terminal Blocks feature a captive nut enclosed within an integrated hinge, ensuring secure and efficient wire clamping. Designed for reliable high-current connections, the captive nut can be easily fastened using a screwdriver onto the current bar.
