The Siemens 5SU1654-7KK06 is a robust residual current circuit breaker with overcurrent protection (RCBO) that ensures a high level of safety in electrical installations. This component is part of the SENTRON protection device range, designed to detect and isolate faults to prevent electric shock and fire hazards caused by earth faults.
With a 10 kA breaking capacity and a C-type tripping characteristic, this RCBO is well-suited for commercial and industrial applications where sudden high power loads are common. It features a 1P+N pole configuration, with a single pole and neutral, and is rated for a 6 A operating current at an AC supply voltage of 230/240 V.
The device is engineered to provide protection against both overcurrents, such as short circuits and overload conditions, and residual fault currents with a rated sensitivity of 300 mA. This sensitivity level is particularly useful in environments where additional protection against indirect contact and fire is required.
The 5SU1654-7KK06 is designed with user safety in mind, offering touch protection and neutral conductor switching. It is also halogen-free and silicon-free, making it an environmentally conscious choice. The compact design, with a width of only 36 mm, allows for efficient use of space within distribution boards.
Installation is made straightforward with a flexible power supply cord connection that can be positioned either at the top or bottom of the device. It accommodates a wide range of conductor cross-sections, from 0.75 mm² to 35 mm² solid or stranded, and up to 25 mm² for finely stranded conductors with core end processing.
The RCBO's mechanical design ensures durability, with a mechanical service life of typically 10,000 switching cycles. It operates reliably within a broad temperature range, from -25 °C to 55 °C during operation, and can be stored in temperatures ranging from -40 °C to 75 °C.
This Siemens RCBO is a critical component for electrical safety, providing reliable protection and peace of mind in a variety of settings. Its technical proficiency and compliance with international standards make it a valuable addition to any electrical system.
