The Siemens 5SU1356-7KK10 is a state-of-the-art residual current circuit breaker (RCBO) designed to provide exceptional protection in electrical circuits. This compact device combines the functions of a miniature circuit breaker and a residual current device, ensuring both overcurrent protection and earth fault detection. With a rated current of 10 A and a tripping characteristic class C, it is well-suited for commercial and industrial applications where surge currents can be expected.
The RCBO has a rated voltage of 230 V AC and is capable of withstanding impulse currents up to 1 kA, making it robust against transient voltage spikes. It features a 1P+N pole configuration, ensuring that both the phase and neutral conductors are disconnected simultaneously in the event of a fault, which is essential for maintaining safety. The device is designed to trip at fault currents of 30 mA, providing additional protection against electric shock and fire hazards caused by earth faults.
With a mechanical service life of 10,000 cycles, the Siemens 5SU1356-7KK10 is built for longevity and reliability. Its compact dimensions, 90 mm in height, 36 mm in width, and 77 mm in depth, allow for efficient use of space within distribution boards. The RCBO is also halogen-free and silicon-free, minimising environmental impact and ensuring compliance with stringent environmental standards.
The 5SU1356-7KK10 is easy to install and can accommodate a wide range of conductor cross-sections, from 0.75 mm² to 35 mm² for solid and stranded wires, and up to 25 mm² for finely stranded wires with wire end processing. The tightening torque for screw-type terminals is specified between 2.5 N·m and 3 N·m, ensuring secure and reliable connections.
This RCBO is an essential component for modern electrical installations, offering both protection and peace of mind. Its robust design and precise tripping characteristics make it a valuable addition to any electrical system requiring enhanced safety measures.
