Choose switch disconnectors that protect your network from overloads
What should you look out for when choosing isolating switches?
Switch disconnectors play a key role in every electrical installation, protecting it from the effects of short circuits and overloads. Therefore, the purchasing decision requires not only analyses of technical parameters (e.g. rated current, mechanical endurance, IP rating), but also an assessment of other factors that affect the safety of the installation and personnel. Here are a few of them:
- features – find out whether the switch disconnectors can lock the drive in a specific position and whether they offer the option to change the up/down direction of movement. Check whether they allow for contactless replacement of fuse links and remote monitoring;
- safety – verify standards compliance with Polish and European standards, confirmed by certificates. Check the design for optimal heat dissipation, flammability class and level of protection against direct contact;
- installation flexibility – assess the speed and ease of installing the switch disconnectors for staff. Check which mounting systems the device is compatible with (e.g. busbars, mounting plates, DIN TH-35 rails);
- infrastructure compatibility – enquire about related solutions, e.g. switchgear monitoring software, busbar systems or product standardisation within a single solution group.
