Features of F12 Auxiliary Switches

High-Quality Contact Material: Both moving and fixed contacts are crafted from AgNi10, ensuring excellent conductivity, strong arc-erosion resistance, and long-term operational reliability.

Double-Break Bridge Structure: Featuring low contact resistance, fast opening speed, and excellent arc-extinguishing performance.

AC/DC Control Circuit: Compatible with both alternating AC and DC control circuits, satisfying diverse secondary application demands.

Specialized DC Contacts: Optional dedicated contacts engineered for DC 110V/220V closing and opening coils, delivering up to 10A breaking capacity at DC 220V.

Broad Mechanism Adaptability: Seamlessly matching diverse spring operating mechanisms in medium- and high-voltage switchgear for reliable mechanical interlocking and sequence control.

Flexible Customization: Tailored options for contact configurations, dedicated DC modules, time-delay setups, and mounting methods to suit complex mechanisms.
