IntroductionBarrier Blocks are an important type of terminal blocks, which provide reliable electrical connections and prevent the flow of electricity through the circuit board. YK4140303000G is a new and special type of barrier blocks which provides complete protection against voltage overshoot or short circuit, ensuring maximum safety of your electronic equipment. This article will discuss the application field and working principle of YK4140303000G. Application Field YK4140303000G is widely used in many industries such as automotive, telecommunications, sensing, instrumentation and industrial control systems. It is also used in all safety and danger application field such as computers, industrial equipment, security systems, FA systems and monitoring systems. YK4140303000G consists of two pieces of base which are connected by a terminal. It is capable of accepting up to 30AWG wire, making it an ideal choice for applications with high current and voltage requirements. It has an operating temperature range of -40°C to 105°C and can withstand temperatures up to 130°C for short periods of time. YK4140303000G is constructed using a special polyamide material which is resistant to shock, vibration and moisture. The base of the terminal block is made from a UL 94V-2 approved blue plastic, which makes it highly resistant to short circuit and voltage overshoot. The UL 60601-1 medical grade terminal also has a heavy-duty pin contact, making the YK4140303000G suitable for up to 250V AC or 15A. Working PrincipleYK4140303000G operates on the same principle as other barrier blocks. The base of the barrier block is built with four different contact points – two for the incoming and two for the outgoing wires. The incoming wires are then connected to the base, and the barrier block then prevents the current from travelling through the circuit. The second contact point of the barrier block serves as an overshoot protection. When a current flow of over 20A is detected, it goes through the overshoot protection and immediately shuts off the cable. This prevents any further damage to the equipment and circuit. The third contact point of the barrier block is used as a short-circuit protection. A small gap is provided between two of the contact points and when a short circuit occurs in the circuit, the current flow will be directed towards the ground, preventing any further damage. Conclusion YK4140303000G is an effective terminal block that offers reliable connections and protection against overshoot and short circuits. It is suitable for use in industries such as automotive, telecommunications, sensing, instrumentation and industrial control systems. It also has a UL 94V-2 approved base and a medical grade terminal, making it ideal for applications with high current and voltage requirements. This article has discussed the application field and working principle of YK4140303000G. It is an effective and reliable terminal block and is suitable for a wide range of applications. It also provides effective protection against overshoot and short circuits.
