F10-6 Circuit Breaker Control Switch 3NO3NC

Features of F10-6 Circuit Breaker Control Switch

Plane Sliding Contact Technology

The moving contact features a dual-blade sliding design that maintains constant contact pressure. This eliminates point-contact gaps, minimizes contact resistance, and prevents thermal buildup during continuous high-current signal transmission.

Modular Stacked Architecture

Designed with a “building block” modular structure, this switch offers excellent field flexibility. Engineers can easily scale the number of contact stages up or down to match changing secondary circuit requirements without replacing the entire unit.

Zero-Delay Signal Synchronization

The internal mechanism responds instantly to the primary breaker’s status. It ensures zero-delay transmission of auxiliary position signals to protection relays and PLC control systems, preventing interlocking failures.

Industrial-Grade Durability

Built with wear-resistant, anti-aging internal components and a flame-retardant polymer outer shell. The rugged housing provides excellent dielectric strength and arc resistance, ensuring stable performance in harsh substation environments.

Universal Form Factor Replacement

Featuring standard square shaft dimensions and industrial mounting hole pitches, the F10-6 acts as a direct, drop-in replacement for worn-out switches in existing KYN28 or similar medium-voltage switchgear.

Working Conditions

1. Ambient Temperature (-40℃≤ t ≤40℃)

2. Height above Sea Level (h≤3000m)
