Introduction

The 431605-12-0 application field and working principle are a key component of the terminal block product range. This type of barrier block is highly suitable for connecting components and controls, and widely used in electronics, power distribution, and many other industrial applications. With its two press fit terminals and safe two-pole connection, it provides secure and reliable electrical connections.

Design Features and Specification

The 431605-12-0 terminal block is designed to provide dual controlled, short-circuit protection. The two-pole configuration of the barrier block allows one side to be opened and the other to be closed. Thus both sides of the connection can be controlled individually and used to provide a short-circuit protection. The two press fit terminals included allow for easy assembly and superior contact reliability. The centralized design of 431605-12-0 terminal block allows for easy installation and handling.The barrier blocks are RoHS compliant, UL and CE certified, and they comply with standards such as IEC, UL, and CSA. The contact surface is nickel-plated for improved surface-to-surface contact. The two terminals on each block are pressed-in contacts for high reliability. The contacts have a current rating of 2A at 50VAC. The terminal blocks also have a dielectric strength of 1000V.

Functional principle

The 431605-12-0 terminal block works on the principle of short-circuit protection. The two-pole configuration of the barrier block allows for one side to be closed and the other to be opened. This prevents any dangerous short-circuit currents. The two press fit terminals that are included when the blocks are purchased ensure that a good electrical connection is made.The functions of the terminal blocks are comprehensively tested in accordance to EN 60950-1:2008 standards. The terminal blocks are tested for electrical shock protection, overcurrent protection, and mechanical safety. The mechanical safety tests ensure that it is impossible to inject unwanted currents from the outside. The overcurrent protection test guarantees that the current does not exceed 2A at max. voltage of 50VAC.

Conclusion

The 431605-12-0 terminals and working principle are an important part of the terminal block product range. These barrier blocks offer superior performance and reliability for both power distribution and control signals. They guarantee safe electrical connections with their two-pole connection and two press fit terminals. The 431605-12-0 terminal block is a highly reliable and safe electrical connection option, and complies with standards such as IEC, UL and CSA.
