FAQ Related To Insulators
Is the auxiliary switch reliable under frequent operations? What is its service life? Expand
The auxiliary switch is a core component for circuit breaker interlocking and signaling. Our auxiliary switches utilize high-quality silver alloy contacts, which provide extremely low contact resistance. Durability: The mechanical life typically reaches over 100,000 cycles. Compact & Robust Design: Due to its compact footprint, it is ideal for installation within the confined spaces of switchgear such as the KYN28 series. Furthermore, it is engineered to withstand the intense vibrations during switching operations, ensuring uninterrupted signal transmission.
