CY4/3

Product Description

SB Smart CY4/3 is a premium quality 4 sq.mm 3 Wire Feed Through Terminal Block specially designed for secure multi-wire conductor termination in industrial control panels, switchgear assemblies, PLC systems, automation equipment, machine wiring, and electrical distribution applications. This advanced terminal block is engineered to connect three conductors in a single compact terminal block, eliminating reliability issues that often occur when multiple wires are connected under one single clamp. It is an ideal solution for professional electrical installations where safe wiring, organized conductor management, and compact space-saving design are essential.

The CY4/3 terminal block features a 3 wire feed-through connection system, allowing multiple conductors to be securely connected within one compact terminal block. This design simplifies wiring layouts and reduces the need for additional looping or jumper connections in electrical panels. By allowing three separate conductor connection points in one block, the SB Smart CY4/3 helps electricians and panel builders improve panel wiring organization, reduce installation time, and maintain professional electrical standards in industrial and commercial applications. It is especially useful in compact control panels where multiple connections need to be terminated in limited panel space.

Designed for 4 sq.mm conductor capacity, the SB Smart CY4/3 supports stranded and solid conductors, making it suitable for a wide range of industrial and commercial wiring applications. The terminal block offers a rated voltage of 500V (IEC) and a 32A current carrying capacity, ensuring safe and stable electrical performance in industrial control systems, machine wiring, automation panels, PLC systems, instrumentation circuits, and electrical distribution applications. Its feed-through design provides dependable conductor-to-conductor electrical continuity with low resistance current transfer and reliable long-term electrical performance.

Manufactured using high conductivity copper alloy conductive parts, the SB Smart CY4/3 ensures excellent electrical conductivity, low resistance current transfer, and dependable long service life. The conductive elements are specially designed to maintain stable electrical flow while minimizing heat generation during operation. This improves electrical efficiency and ensures safe performance in demanding industrial environments where secure conductor termination is critical. The optimized conductive design also improves connection reliability and reduces maintenance issues over time.

The SB Smart CY4/3 features a screw clamp connection system, which provides strong conductor holding force and vibration-resistant electrical contact. Unlike conventional loose conductor connections, the screw clamp mechanism ensures secure conductor termination and long-term connection stability. The terminal block uses an M3 screw system and is screwdriver operated, allowing easy conductor insertion, secure tightening, and convenient maintenance during installation or servicing. This makes it a preferred choice for industrial electricians, control panel manufacturers, and automation professionals seeking reliable conductor connection solutions.

Built with a high-grade polyamide insulated housing, the SB Smart CY4/3 provides excellent electrical insulation, mechanical strength, heat resistance, flame resistance, and long service life. The insulated body protects conductive components from accidental contact and environmental effects, improving operational safety in industrial electrical installations. The grey color body makes it suitable for standard electrical panel wiring applications and helps maintain clean, organized terminal block layouts in professional electrical systems.

The terminal block is designed for side wire entry configuration, allowing easy conductor insertion and efficient cable routing in compact electrical enclosures. It is compatible with DIN 35 / DIN 35-15 rail mounting, enabling quick installation in standard electrical panels, switchgear assemblies, and industrial control systems. Its compact modular construction helps save panel space while improving wiring flexibility and accessibility during installation and maintenance.

With a rated surge voltage of 8KV, tightening torque of 0.5 Nm, and pollution degree 3, the SB Smart CY4/3 is designed to perform reliably in industrial environments where electrical disturbances, voltage spikes, and harsh operating conditions may occur. Its rugged industrial-grade construction ensures dependable long-term performance and safe operation in demanding applications. This makes it an ideal terminal block for OEM manufacturers, industrial electricians, automation engineers, and panel builders seeking professional wiring solutions.

SB Smart CY4/3 is widely used in industrial control panels, automation systems, PLC panels, switchgear assemblies, machine control circuits, instrumentation panels, OEM electrical equipment, process industries, and industrial electrical wiring applications where secure multi-wire conductor termination is required. Its compact design, 3 wire connection capability, safe insulated housing, and reliable screw clamp technology make it an excellent solution for professional electrical installations.
