CSB3/N3USH is a stud type hinge disconnect terminal block specially designed for industrial electrical systems where lug-based conductor termination, safe circuit isolation, and maintenance-friendly testing access are required. In electrical control panels, PLC cabinets, instrumentation systems, switchboards, industrial automation panels, and process control applications, engineers often need a terminal block that can provide both secure stud-based conductor locking and manual circuit disconnection during testing or servicing. This is especially useful in circuits where maintenance must be carried out without disturbing the complete electrical system.
Unlike standard stud type terminal blocks, the CSB3/N3USH includes a hinge disconnect mechanism, which allows the electrical path to be manually opened for testing, fault tracing, and circuit isolation. The conductor is terminated using a ring lug or fork lug over an M3 stud connection, ensuring strong mechanical wire retention even in vibration-prone industrial applications. This makes it highly suitable for industrial electrical systems where safe circuit interruption, secure lug-based wiring, and reliable electrical continuity are critical.
This terminal block is ideal for applications where circuits need to be isolated temporarily during maintenance, testing, commissioning, or troubleshooting while maintaining secure conductor termination.
The CSB3/N3USH operates as a stud type hinge disconnect terminal block, where a conductor terminated with a ring lug or fork lug is mounted over the M3 stud connection and securely tightened using a nut. A built-in hinge disconnect link allows the electrical circuit to be manually opened or closed whenever required.
Its working design provides:
This makes the terminal block highly suitable for industrial applications where circuit interruption and secure conductor retention are equally important.
The CSB3/N3USH improves electrical safety by combining secure stud termination and safe disconnect capability in one terminal block.
