Kits are for mechanically interlocking two identical contactors. Prevents the second contactor from pulling-in if the first is energised.

For the safe switching of your contactors, latch onto this mechanical interlock from Schneider Electric. It's a versatile component that's designed for use with devices in the LC1 series, including the LC1D09 and LC1D12. The unit works by linking two contactors' contacts to ensure they're never energised at the same time, reducing the risk of damage or electrical fire. The piece of kit comes complete with the wiring and cover needed for quick and simple installation. You don't need complex tools to set it up, so that's one more thing to strike off your to-do list.

• HVAC systems
• Electricity transmission and distribution stations
• Telecommunications industry

No, this unit is self-contained and is a mechanical device, so it doesn't need any external power to function. This means it continues to do its job even in the event of an outage.
