Application: Suitable for Withdrawable Circuit Breakers (e.g., ZN63/VB1 Series)
The GC5-1250A (30 Fingers) Tulip Contact, also known as a Rose or Finger Contact, is the primary moving contact for vacuum circuit breakers and a core conductive component in high-voltage switchgear. It is widely used in withdrawable switchgear units and medium-voltage circuit breakers requiring higher current-carrying capacity.
Mounted on the circuit breaker truck, the tulip contact securely grips the fixed (static) contact when the truck is levered into the "Work" position, completing the electrical circuit. Designed for reliability and performance under increased current loads, it meets stringent industry standards for electrical conductivity and mechanical durability.
This tulip contact is widely used in:
ZN63 (VS1)-12 Series indoor vacuum circuit breakers
VB1 Series withdrawable circuit breakers
KYN28 (GZS1) medium-voltage switchgear
Other withdrawable switchgear applications requiring reliable primary circuit connection at 1250A rating
Designed as a high-performance component, the GC5-1250A tulip contact ensures safe and efficient power distribution in AC power systems with rated frequency of 50Hz and rated voltage up to 12kV.
