Frequently Asked Questions
Q: What current ratings are available for the LW30 rotary circuit breaker switch?
A: The LW30 is available in six current ratings: 25A, 32A, 40A, 63A, 80A, and 100A. Choose the rating that matches your circuit's load requirements to ensure safe and efficient operation.
Q: Can the LW30 be used for both single-phase and three-phase circuits?
A: Yes. The LW30 is a universal conversion switch compatible with both single-phase and three-phase electrical systems operating at 50 Hz, making it suitable for a wide range of residential, commercial, and light industrial applications.
Q: What makes the silver contacts important in this rotary switch?
A: Silver contacts offer lower electrical resistance compared to standard contacts, which means less heat generation, reduced arcing during switching, and a significantly longer operational lifespan — all critical factors in a reliable load isolation switch.
Q: How is the LW30 switch installed?
A: The LW30 is designed for panel-mount installation in standard electrical distribution boards and control panels. Always ensure the circuit is de-energised before installation and follow local electrical codes. If in doubt, consult a qualified electrician.
