SB Smart CPDLG4 is a high-performance 4 sq.mm Push-In Disconnect Terminal Block designed for secure conductor termination, quick circuit isolation, and efficient panel wiring in industrial control panels, automation systems, PLC panels, switchgear assemblies, instrumentation circuits, machine control systems, and OEM electrical applications. This advanced disconnect terminal block combines push-in connection technology with integrated disconnect functionality, making it an ideal solution for industrial electrical systems where reliable conductor connection, easy testing, and safe signal isolation are essential.
The SB Smart CPDLG4 disconnect terminal block is specially engineered to provide safe electrical continuity during normal operation and fast circuit interruption whenever testing or maintenance is required. In conventional wiring systems, isolating a circuit often requires manual wire disconnection, which can increase downtime and maintenance complexity. The SB Smart CPDLG4 solves this issue by integrating a disconnect mechanism directly into the terminal block, allowing electricians and maintenance engineers to isolate circuits quickly and safely without disturbing adjacent wiring.
One of the major highlights of the SB Smart CPDLG4 is its advanced Push-In spring clamp connection technology, which enables tool-less wire insertion for faster and more efficient wiring. The push-in connection creates a gas-tight, vibration-resistant, and maintenance-free conductor connection, ensuring dependable electrical contact over long service periods. Compared to conventional screw terminals, this technology reduces installation time, improves conductor safety, and minimizes maintenance requirements in industrial electrical systems.
Designed for 4 sq.mm conductor capacity, the SB Smart CPDLG4 supports both solid and stranded conductors, making it suitable for industrial control circuits, automation systems, PLC panels, signal wiring, instrumentation circuits, machine control applications, OEM electrical equipment, and industrial electrical panels. It offers a rated voltage of 800V and a rated current of 32A, ensuring safe and stable electrical performance in demanding industrial applications where circuit isolation and reliable conductor termination are critical.
Manufactured using high conductivity copper alloy conductive components, the SB Smart CPDLG4 ensures excellent electrical conductivity, low contact resistance, and stable long-term current transfer. The conductive parts are specially designed to reduce electrical losses and minimize heat generation during operation, improving electrical efficiency and ensuring dependable circuit continuity in industrial control systems.
Built with a high-grade flame retardant polyamide insulated housing, the SB Smart CPDLG4 provides excellent electrical insulation, heat resistance, flame resistance, mechanical strength, and long service life. The insulated housing protects conductive components from accidental contact and environmental stress, improving electrical safety in industrial panels and control systems. Its grey color body makes it suitable for standard electrical wiring and organized terminal block layouts in professional installations.
The integrated disconnect slide mechanism allows quick and safe circuit interruption for testing, troubleshooting, maintenance, calibration, and signal isolation applications. This feature helps reduce downtime, improve maintenance efficiency, and enhance safety in industrial electrical systems where regular testing or circuit isolation is required.
Designed for DIN rail mounting, the SB Smart CPDLG4 allows fast and secure installation in standard electrical control panels and switchgear assemblies. Its compact modular construction saves valuable panel space while improving conductor organization and wiring accessibility inside electrical enclosures.
With a rated surge voltage of 8KV and pollution degree 3, the SB Smart CPDLG4 is engineered to perform reliably in industrial environments exposed to electrical disturbances, dust, voltage fluctuations, and continuous operating stress. Its rugged industrial-grade design ensures dependable long-term service in demanding industrial applications.
SB Smart CPDLG4 is widely used in industrial control panels, automation systems, PLC panels, instrumentation circuits, signal isolation applications, switchgear assemblies, machine control circuits, process industries, OEM electrical systems, and industrial electrical installations where safe disconnect functionality and reliable conductor termination are required.
