The Siemens 5SY4140-7 is a robust miniature circuit breaker designed to provide reliable overcurrent protection for electrical circuits. This toggle-operated breaker is rated for 400 V and can handle a 5 kA interrupting capacity, making it suitable for a wide range of industrial and commercial applications. With a 40 A current rating and thermal-magnetic trip characteristics, it ensures both thermal overload and short-circuit protection.
Crafted for quick and easy installation, the 5SY4140-7 features a screw terminal connection and is designed to be DIN rail mounted, which allows for efficient use of panel space. The compact dimensions of 17.6 x 76.4 x 89.8 mm make it an ideal choice for space-constrained environments. Its tripping characteristic class C indicates a medium trip curve, making it well-suited for applications with moderate inrush currents, such as small motors and lighting circuits.
The circuit breaker's design adheres to stringent quality standards, ensuring both durability and reliability. It is a versatile component that can be used across various sectors, including mechanical engineering and industry, providing a high level of protection and maintaining circuit integrity.
