YK4210403000G

Terminal Blocks - Barrier Blocks

Barrier blocks are one type of terminal blocks, which offer a manageable and secure way to make electrical connections. The YK4210403000G is a widely used barrier block, with applications mainly in the industrial automation and control sector. It is particularly common in buildings and sites where large numbers of connections must be reliable, easily accessed, and fast to change.

Component Parts of YK4210403000G

The YK4210403000G consists of several parts, including anchoring screws, pressure spacers, insulating parts, terminals and contact pins. The contact pins are made of copper, with the ends of the pins having an 8x0.3 mm shape, meeting the international standard IEC 60947-7-1. The circumferential cable protection avoids direct contact between conductors and insulating parts, reducing the risk of short-circuits.

Operating temperature Range

The operating temperature range of YK4210403000G is -40 to +105°C, and the rated current of 8A per pin. The rated voltage of YK4210403000G is 380V, with the insulation resistance being more than 2,000MΩ(500V DC). In addition, the dielectric strength performance is also excellent, with the dielectric strength between same poles being 2,500 V AC for one minute, and the dielectric strength between adjacent poles being 2,000 V AC for one minute. These figures meet higher safety requirements for industrial connections.

Protection Degree of YK4210403000G

The protection degree of YK4210403000G is IP20, so it offers reliable protection of front-end conductors or components, and is dust-proof and drip-proof. It is suitable for control systems with a higher level of protection, typically used in high-quality automation systems. YK4210403000G can provide a reliable connection connection even in rugged industrial environments.

Working Principle of YK4210403000G Barrier Blocks

The YK4210403000G consists of two parts - a base and a housing. When the connection is made, the contact pin is inserted into the screw clamp and tightened, hence the connections are established. The clamping force provided by the screws generates a self-locking design, so that the pins firmly hold in place and reduce the possibility of wobbly and faulty connections. The insulation spacers can also lower the possibility of incorrect connections, thus ensuring secure connections.

Applications of YK4210403000G

The YK4210403000G is the preferred choice for many industrial applications, typically used in signal splitting, control circuit wiring, power supply wiring, motor control, input and output wiring, and for any other application requiring terminal blocks. Its compact design and reduced size can save up to 40% of space. The easy installation and high level of protection provide a reliable connection in harsh industrial environment.
