Product information

Description

The Siemens 5TL1391-0 modular disconnector is a professional-grade electrical component engineered for the secure isolation of circuits within industrial and commercial power distribution systems. With a robust 100A rated current and a 3-pole configuration, this device provides reliable performance for managing electrical loads at a 400V operating voltage. Its compact modular design allows for seamless integration into standard distribution boards, ensuring efficient power control and enhanced safety for electrical installations.

Advantages

This modular disconnector stands out due to its high-quality construction and adherence to strict safety standards, which are hallmarks of the Siemens brand. The device offers a dependable solution for manual circuit disconnection, allowing maintenance personnel to isolate specific sections of an electrical system safely. Its durable design ensures long-term operational stability, while the standardized form factor simplifies the installation process for electrical professionals, reducing setup time and complexity in various distribution environments.

Suitable for

  • Industrial electrical distribution boards
  • Commercial building power management systems
  • Manual isolation of three-phase electrical circuits
  • Professional electrical infrastructure projects

When it may not be suitable

This device is not intended for use in residential applications where a 100A rating exceeds the standard circuit requirements. It is also not suitable for environments exposed to extreme moisture or corrosive elements without appropriate protective enclosure housing.

Key specifications

  • Rated current: 100A
  • Number of poles: 3
  • Operating voltage: 400V
  • Weight: 0.321 kg
  • Design: Modular for distribution boards

How to use

The Siemens modular disconnector should be installed by a qualified electrician in accordance with local electrical codes. It is designed to be mounted onto a standard DIN rail within a distribution board. Once securely installed, the device is operated manually via the front-facing toggle to connect or disconnect the power supply to the downstream circuit. Ensure all connections are tightened to the specified torque settings to prevent overheating and ensure optimal electrical contact.

What to consider before purchase

  • Verify that the 100A current rating matches your circuit requirements
  • Ensure the 3-pole configuration is compatible with your three-phase system
  • Confirm that your distribution board has sufficient space for a modular device
  • Check that the 400V operating voltage aligns with your electrical network

Usage recommendations

Always verify that the circuit is de-energized before performing any maintenance or installation work on the disconnector. Regularly inspect the terminals for signs of wear or loose connections to maintain system integrity.
