Introduction
The THA1 tulip electrical contacts are made from imported non-magnetic stainless steel and T2 copper. The function of non-magnetic stainless steel material is to prevent eddy current. Pressure is distributed evenly on the ring spring. The contact pieces of the tulip contacts are silver-plated to prevent oxidation and enhance wear resistance. The THA1 tulip electrical contacts can be used for ABB-VD4, Schneider-EV12S, HVX, SIEMENS-3AE-SION and Tellhow-TZN series of vacuum circuit breakers, etc.
Features
1. Pressure is distributed evenly on the ring spring.
2. Non-magnetic stainless steel material is used to prevent eddy current.
3. Overall silver-plated contact pieces have good wear resistance.
4. Anti-tarnishing treatment is performed to avoid silver layer oxidation and falling off.
5. Static contact insertion depth (reference value): 34 ± 2mm.
