This Siemens 5SJ42308HG41 is a 2-pole miniature circuit breaker designed for reliable circuit protection. It features a D-trip characteristic and a rated current of 30A, with a significant switching capacity of 10kA according to EN 60898.
The breaker operates with a supply voltage of up to 400V AC and is suitable for use in mechanical engineering and industrial applications. It offers a protection class of IP20 with connected conductors and IP40 in the handle range. The unit is designed for easy installation on a standard DIN rail.
Key electrical specifications include an insulation voltage of 440V AC and a power loss of 3.2W per pole at rated current in a hot operating state. The operational current is rated at 30A at 40°C, with derating at higher temperatures. The breaker supports conductor cross-sections from 0.75mm² to 25mm² for finely stranded conductors with core end processing.
Additional features include touch protection, sealability, and the capability to install supplementary devices. The breaker is halogen-free and silicon-free, contributing to environmental considerations in its application.
