Product information

Description

The Siemens 3LD Switch Disconnector 3P IP65 Multicolour is a reliable device engineered for the safe disconnection and control of electrical circuits. Designed as a 3-pole switch disconnector, it features a robust construction suitable for demanding industrial and commercial environments. This unit provides dependable operation with a 16 A rated current and a 7.5 kW operating power at AC-23 A 400 V, making it an essential component for power distribution applications, control panels, and machinery safety isolation.

Advantages

This Siemens switch disconnector ensures high operational safety through its reliable locking capability of the rotary operating mechanism, effectively preventing accidental activation during maintenance. The IP65 protection rating guarantees resistance against dust and water jets, allowing for secure outdoor use and deployment in harsh industrial settings. Its modular design enables fast and straightforward mounting, while international approvals ensure compatibility for global applications across various industries.

Suitable for

  • Safely disconnecting three-phase motors in industrial machinery
  • Emergency switching-off operations in control panels
  • Power distribution in commercial and manufacturing facilities
  • Isolation tasks in heating, ventilation, and air conditioning systems

When it may not be suitable

This switch disconnector is not designed for low-current domestic wall socket installations or standard household appliances. It is also unsuitable for applications requiring direct high-voltage power transformation or circuits exceeding its specified operational ratings without proper auxiliary equipment.

Key specifications

  • Number of poles: 3P
  • Protection rating: IP65
  • Rated current: 16 A
  • Operating power at AC-23 A 400 V: 7.5 kW
  • Product colour: Multicolour (Red and yellow rotary handle)
  • Mounting type: Floor mounting with door coupling and 22.5 mm central handle mounting
  • Weight: 425 g

How to use

Installation should be performed by qualified electrical personnel in accordance with local safety regulations and standard wiring practices. The device is typically installed via floor mounting with door coupling, utilising the rotary operating mechanism for manual control. Ensure the system is powered off before mounting or performing any wiring tasks. The rotary handle allows for clear visual status indication and can be locked in the off position to ensure safety during maintenance procedures.

What to consider before purchase

  • Verify that the 16 A rating and 7.5 kW operating power match your specific circuit requirements
  • Confirm that the IP65 enclosure and door coupling mechanism suit your physical panel layout
  • Check local electrical standards and ensure compatibility with three-phase motor or machinery isolation needs

Always disconnect the main power supply before installing, servicing, or operating the Siemens 3LD switch disconnector. Regular inspection of the enclosure and mechanical locking elements is recommended to maintain optimal safety and performance.

International Protection (IP) code: The IP code classifies and rates the degree of protection provided against the intrusion (including body parts such as hands and fingers), dust, accidental contact, and water by mechanical casings and electrical enclosures. It is published by the International Electrotechnical Commission (IEC). The digits (characteristic numerals) indicate conformity with the conditions summarized in the tables below. Where there is no protection rating with regard to one of the criteria, the digit is replaced with the letter X. an electrical socket rated IP22 is protected against insertion of fingers and will not be damaged or become unsafe during a specified test in which it is exposed to vertically or nearly vertically dripping water. Another example is the Sony Xperia Z Ultra, one of the first cellular phones to be IP-rated; it is rated at IP58 and marketed as "dust resistant" and can be "immersed in 1.5 meter of freshwater for up to 30 minutes".
