Panel Mount Screw Clamp Terminal Block, 4mm², Green – CMB4GN

Product Description

The CMB4GN Panel Mount Terminal Block is a high-quality 4 sq.mm panel mount feed-through terminal block designed for safe, secure, and efficient electrical conductor termination in industrial and commercial electrical systems. It is specially engineered for applications where compact wiring, reliable conductor connection, and organized panel assembly are essential. This terminal block is widely used in electrical control panels, switchgear assemblies, automation systems, machine control cabinets, OEM electrical assemblies, power distribution boards, and industrial machinery wiring applications where dependable electrical continuity and compact installation are required. The green color coding makes it ideal for circuit identification in electrical panel applications, helping electricians and panel builders create organized and professional wiring systems.

In modern electrical systems, space-saving and organized wiring solutions are critical for maintaining safe and efficient electrical connections. The CMB4GN Panel Mount Terminal Block is specially designed for extremely compact wiring applications and can be stacked together to form multi-pole terminal block assemblies. This modular design makes it an excellent solution for electrical installations where multiple conductor terminations need to be arranged in a compact and professional manner. The product reduces wiring clutter, improves panel organization, and simplifies maintenance work in industrial control cabinets and electrical enclosures.

The CMB4GN is designed for 4 sq.mm conductor capacity, making it suitable for medium-power electrical circuits and industrial control applications. It supports a rated voltage of 500V and a rated current of 32A, ensuring reliable electrical continuity in a wide range of industrial and commercial electrical installations. These electrical ratings make the product ideal for safe conductor termination in machine control panels, power distribution circuits, automation systems, and electrical panel assemblies.

One of the major advantages of the CMB4GN Panel Mount Terminal Block is its feed-through connection design. This design allows secure electrical continuity between incoming and outgoing conductors through a strong screw clamp mechanism. The screw clamp technology ensures reliable wire fastening, low contact resistance, and strong conductor retention, which helps reduce the chances of loose wiring, overheating, or electrical faults. This makes the terminal block suitable for industrial environments where vibration, continuous electrical operation, and mechanical stress demand secure conductor termination.

The terminal block uses a side wire entry configuration, allowing convenient conductor insertion even in compact panel layouts. Side entry wiring improves installation flexibility and simplifies conductor routing inside control cabinets, switchgear panels, and distribution boards. This design makes installation easier for electricians and reduces assembly time during panel manufacturing.

Another key advantage of the CMB4GN Panel Mount Terminal Block is its panel/surface mounting capability. Unlike DIN rail terminal blocks, this product is designed to be mounted directly onto panel surfaces, making it suitable for electrical systems where direct mounting is required. This flexibility allows use in customized control cabinets, machine panels, compact enclosures, and OEM electrical assemblies. Its compact body helps optimize panel space while maintaining reliable conductor connection and professional wiring organization.

The terminal block is built using durable polyamide insulated housing, which provides excellent electrical insulation, mechanical strength, heat resistance, and flame retardant properties. The insulated body protects conductors from accidental contact and helps maintain safe electrical separation inside panels. This makes the CMB4GN highly suitable for industrial applications where electrical safety and long-term durability are essential. The material also provides excellent resistance to heat and environmental stress, improving product reliability over extended operating periods.

For additional electrical safety, the CMB4GN Panel Mount Terminal Block offers 4KV surge voltage resistance, which helps protect circuits from transient voltage spikes and electrical disturbances. This improves overall circuit reliability and protects connected electrical systems from unexpected voltage surges. The product also features pollution degree 3, ensuring dependable performance in industrial environments where dust, moisture, and contaminants may be present. These features make the terminal block a safe and durable conductor termination solution for modern industrial electrical systems.

The CMB4GN also provides excellent installation flexibility through its compact dimensions. With a length of 27 mm, width of 6 mm, and height of 28.5 mm, it occupies minimal panel space while delivering reliable electrical performance. This compact design makes it suitable for applications where space optimization is critical. Its modular construction allows multiple terminal blocks to be stacked side by side to create organized multi-pole terminal assemblies.

The green color coding of the terminal block makes it useful for specific circuit identification applications where electricians use color-coded wiring systems for improved safety and maintenance convenience. This helps reduce wiring errors and simplifies troubleshooting inside electrical panels.

The CMB4GN Panel Mount Terminal Block is widely used in electrical control panels, switchgear systems, industrial automation systems, machine control cabinets, OEM electrical assemblies, renewable energy systems, power distribution boards, commercial electrical installations, industrial machinery wiring, and customized control enclosures where safe conductor termination and compact wiring are essential. It is a trusted solution for electricians, panel builders, switchgear manufacturers, and automation engineers who require reliable panel mount electrical connectivity.

Whether used in industrial control systems, machine panels, commercial electrical projects, or OEM electrical assemblies, the CMB4GN Panel Mount Terminal Block provides dependable electrical continuity, compact installation, and long-term safety for professional electrical applications.
