Products Description
Tulip contact (also known as plum-blossom contact) is a dedicated type of electrical contact fitted to vacuum circuit breakers. Named for their plum-blossom profile, they deliver a larger contact surface and lower contact resistance, which in turn boosts the breaker's electrical performance and operational reliability.
Fabricated primarily from copper, these contacts normally feature silver or gold plating on the surface to enhance electrical conductivity and anti-corrosion capability. Within vacuum circuit breakers, tulip contacts are widely adopted in disconnectors to establish connections for critical high-current, high-voltage electrical components in power circuits.
Features of Tulip Contact
- Annular spring with uniform pressure
- Adopt imported non-magnetic stainless steel,avoid eddy current
- Thick silver coating,strong abrasion strength
- Fixed contact insertion depth for reference: 34+2mm
- Anti-tarnish treatment to prevent oxidation of the silver coating.

Q:1.What is a tulip contact?
A:It is a spring-loaded multi-finger electrical contact for medium voltage vacuum circuit breakers, to carry high current with stable low contact resistance.
Q:2.What is the standard material of tulip contact?
A:Contact fingers: T2 pure copper with silver plating (standard silver thickness 3~8μm, thick plating available). Garter spring: non-magnetic austenitic stainless steel to avoid eddy heating. Holder: copper or insulated support. Brass is not recommended due to poor conductivity and oxidation tendency.
Q:3.What current ratings are available?
A:Standard ratings: 630A,1250A,1600A,2000A,2500A,3150A,4000A.
Q:4.What does the number of contact fingers mean?
A:Finger quantity is designed for rated current. More fingers mean more parallel current paths, lower current per finger and better thermal performance. But it must match original installation dimension and mating diameter. Do not upgrade finger quantity blindly, otherwise poor fitting may occur.
