FAQ
Common questions about LYD11 load break switch selection, application, and installation.
What is the LYD11 load break switch used for?
LYD11 is used for manual ON/OFF switching and safe electrical isolation in low-voltage AC circuits, including distribution boards, switch cabinets, HVAC systems, and pump systems.
Is LYD11 the same as a circuit breaker?
No. LYD11 is a load break switch / isolator switch for manual switching and isolation. It is not designed to provide overcurrent or short-circuit protection like an MCB or MCCB.
What current ratings are available?
Available current ratings include 25A, 32A, 40A, 63A, 80A, and 100A, depending on the application and load requirement.
Can LYD11 be used as a main switch?
Yes. LYD11 can be used as a main switch for isolation and manual load breaking when the selected model matches the system voltage, current, and usage category.
What should be confirmed before ordering?
Please confirm rated current, rated operating voltage, usage category, installation method, handle type, enclosure requirement, and whether padlock or door interlock options are needed.
