The Siemens 5SJ4210-7HG42 is a robust miniature circuit breaker designed to provide reliable overcurrent protection in a variety of applications. Engineered with precision, this 2-pole circuit breaker is rated for 10 kA and can handle currents up to 10 A. It is suitable for both AC and DC circuits, with a rated supply voltage of 400 V for AC and a maximum of 60 V for DC operations.
This circuit breaker is characterised by its C tripping class, ensuring a medium trip curve to protect against both overload and short-circuit conditions. It is compatible with standard mounting rails, making it easy to install in any orientation, and its compact design allows for efficient use of space within electrical enclosures.
The 5SJ4210-7HG42 is designed with safety in mind, featuring touch protection and the ability to be sealed to prevent unauthorised adjustments. It is also halogen-free and silicon-free, contributing to a safer and more environmentally friendly installation.
With a mechanical service life of approximately 20,000 operating cycles, this circuit breaker is built to last and maintain performance over time. Its insulation voltage is rated at 440 V for AC, and it has a breaking capacity short-circuit current (Icn) of 10 kA in accordance with UL 1077 and CSA C22.2 No.235.
The product is suitable for use in mechanical engineering and industrial environments, where reliable circuit protection is essential. Its versatility and high-quality construction make it a valuable component for electrical safety and operational efficiency.
