The Siemens Fuse Switch Disconnector 3NP3530-0CH00 is a robust and reliable component designed for effective circuit protection and isolation. This three-pole switch disconnector is rated for 160 A and can handle voltages up to 690 V ac/dc, making it suitable for a wide range of industrial applications. Its compact design allows for efficient use of space within electrical installations.
Crafted with precision, the 3NP3530-0CH00 features a box terminal connection system that accommodates conductor sizes from 1.5 to 50 mm², ensuring secure and flexible wiring options. The disconnector is compatible with NH00 fuse sizes, which are widely recognised for their high breaking capacity and fast response to overcurrent conditions.
The unit's mechanical design includes a height of 178 mm, a width of 89 mm, and a depth of 118 mm, with a net weight of 523 g. It is designed for fixed mounting on a mounting plate, with the capability for floor mounting as well. The disconnector is not suitable for front or rail mounting, which allows for a more permanent and stable installation.
With an IP00 protection class rating on the front, the disconnector is intended for use in controlled environments where additional protective measures are in place. It can be operated in a wide range of ambient temperatures, from -25°C to +55°C, and is designed to withstand installation altitudes of up to 2000 metres above sea level.
The 3NP3530-0CH00 is not equipped with fuse monitoring and does not function as a main switch or emergency off switch. However, it is suitable for system protection as a switch disconnector and safety switch. Its design does not include auxiliary contacts, which streamlines its function to that of a pure disconnector.
This Siemens Fuse Switch Disconnector is a testament to the brand's commitment to quality, reliability, and innovation in electrical protection technology. It is an essential component for professionals seeking a high-performance solution for safeguarding electrical systems against overcurrent and short-circuit conditions.
