The Siemens 3KF5363-0MF11 is a robust switch disconnector with fuse, designed to handle a substantial current load of up to 630 A. This three-pole unit is engineered for use with low voltage high rupturing capacity (LV HRC) fuses of sizes 2 and 3, ensuring reliable protection and disconnection capabilities in a variety of industrial settings. The switch disconnector is of size 5, which makes it suitable for accommodating the specified fuse sizes with ease.
Crafted for front operation with a central mechanism, the basic unit comes without a handle or flat terminal, allowing for customisation according to specific installation requirements. The SENTRON product line, known for its high-quality and durable electrical components, includes this switch disconnector, which is a testament to Siemens' commitment to excellence in electrical engineering.
With a mechanical service life of 6,000 typical switching cycles and an electrical endurance of up to 1,500 cycles at AC-23 A for 440 V, this device is built to last. It also boasts a short-circuit current making capacity (Icm) of 44 kA at 690 V AC/440 V DC without a fuse link, highlighting its robustness in the face of electrical faults.
The 3KF5363-0MF11 is designed for versatility, with the ability to connect to both copper and aluminium conductors, and offers a range of tightening torques for secure connections. Its mechanical design allows for floor mounting and can be installed in any position, with a net weight of 15.150 kg.
Environmental resilience is another key feature, with an operational temperature range of -25°C to 70°C, ensuring performance in diverse climates. The unit's insulation voltage is rated at 1,000 V, with a surge voltage resistance of 12 kV, providing additional safety and reliability.
This switch disconnector is suitable for use as a main switch, EMERGENCY OFF switch, safety switch, and maintenance/repair switch, among other applications. It is also capable of being sealed for security purposes and can be extended with auxiliary switches or fuse monitoring, depending on the needs of the installation.
The Siemens 3KF5363-0MF11 is a testament to the brand's dedication to providing high-quality, reliable, and adaptable solutions for electrical distribution and protection in industrial environments.
