RHP Series Hybrid Solid State Contactors


RHP Series

Crydom and Digi-Key provide advantages of solid state and mechanical switching technologies in DP contactor package


Crydom has combined solid state and mechanical switching technologies to create its line of Hybrid Solid State Contactors. The RHP contactors (patent pending) provide the performance advantages of both technologies in an industry standard DP contactor package. Crydom’s proven Hybrid SSR technology utilizes contactless solid state turn on and turn off performance, coupled with the very low on state power dissipation characteristic of contactors. This combination results in a fast switching highly reliable contactor that does not require the use of a heat sink.

Available in single and 3 phase versions, Hybrid Solid State Contactors are a cost effective alternative to Mercury Displacement Relays (MDR). RHP contactors are safe and comply with industry standards while offering high power switching capabilities.
