The Siemens 5SY4132-7 is a single-pole miniature circuit breaker from the 5SY series, designed for AC/DC applications with a rated voltage of 400V and a rated current of 32A. It features a C-type tripping characteristic, providing protection against overcurrents and short circuits with a breaking capacity of 10kA according to EN 60898.
This circuit breaker is built for durability, with a typical mechanical service life of 20,000 switching cycles. It offers a high level of safety with touch protection and is suitable for installation using a quick assembly system on a DIN rail. The device has an IP20 protection rating when connected conductors are present.
Key electrical specifications include an insulation voltage of up to 440V for multi-phase operation and a supply voltage frequency of 50Hz. The active power loss per pole is 2.6W at rated current in a hot operating state. It supports a wide range of conductor cross-sections, from 0.75mm² to 35mm² for solid and stranded conductors, and up to 25mm² for finely stranded conductors with core end processing.
The Siemens 5SY4132-7 operates within an ambient temperature range of -25°C to 55°C and has a maximum humidity tolerance of 95%. It is also noted as being halogen-free and silicon-free, contributing to environmental considerations in its application.
