Product information

Description

The Siemens switch disconnector with fuse is an essential electrical component designed for safe circuit disconnection and overcurrent protection in industrial and commercial power distribution applications. Combining reliable switching performance with integrated fuse protection for D02 fuse links, this device ensures effective safeguarding of personnel, equipment, and plants against overloads and short-circuits. Built with a compact 2-pole configuration, it optimizes space within electrical installations while delivering dependable operational safety. The unit features a multicolour housing and weighs approximately 306 grams, making it a robust yet space-saving addition to modern electrical panels.

Advantages

This Siemens switch disconnector provides dual functionality by serving as both a load-break switch and a protective fuse carrier in a single compact unit. Its compact design minimizes space requirements in distribution boards and control cabinets. The device ensures reliable shutdown capabilities during overloads and short-circuits, enhancing overall electrical safety for personnel and machinery. Additionally, the unit supports the attachment of various auxiliary switches and allows for flexible adaptation using reducer sleeves for different fuse sizes, providing high adaptability for diverse installation requirements.

Suitable for

  • Industrial power distribution boards and control panels
  • Commercial building electrical installations
  • Overcurrent and short-circuit protection in low-voltage systems
  • Safe manual circuit disconnection during maintenance work

When it may not be suitable

This device is not designed for domestic consumer units where standard miniature circuit breakers are typically preferred over fuse disconnectors. It is also unsuitable for high-voltage applications exceeding 400 V AC or for circuits requiring currents higher than 63 A.

Key specifications

  • Rated current: 63 A
  • Rated voltage: 400 V AC
  • Number of poles: 2P
  • Compatible fuse links: NEOZED size D02
  • Product colour: Multicolour
  • Weight: 306 g

How to use

The switch disconnector should be installed within a compatible electrical enclosure or distribution board by a qualified electrician in accordance with local safety regulations and wiring standards. Ensure that the system power is switched off before performing any installation or maintenance tasks. Mount the unit securely onto a standard mounting rail. Insert the appropriate adapter sleeves and D02 fuse links, which are sold separately, according to the specific circuit requirements. Once properly installed and wired, the device can be manually operated to connect or disconnect the circuit, and provides reliable automatic interruption in the event of an electrical fault.

What to consider before purchase

  • Verify that the 63 A rating and 400 V AC voltage match your electrical system requirements.
  • Confirm that compatible D02 fuse links and adapter sleeves are obtained separately, as they are not included with the unit.
  • Ensure sufficient space is available within your distribution board for a 2-pole device.
  • Check whether auxiliary switches or reducers are needed for your specific application setup.

Installation and maintenance of this switch disconnector must be performed exclusively by certified electrical professionals in compliance with applicable technical standards and safety guidelines.
