... Two accessories, shown in Figure 4, are available for use with the Crydom 3RHP 3 Phase Solid State Contactor, including a DIN rail mounting bracket that can be installed on the 3RHP mounting base (DMB3), and an external auxiliary contact switch (HAC1). The auxiliary switch includes one normally open and one normally closed contact, each rated at 5 amps rms, 600 VAC, 50 ...

... CONCLUSIONS The Crydom 3RHP series of 3 Phase Hybrid Solid State Contactors provide a cost effective alternative to Mercury Displacement Contactors and Relays in many applications. The 3RHP also can economically be employed in EMR contactor or Relay applications where life expectancy requirements exceed available contactor ratings. Available 3RHP logic compatible control inputs also offer a means to eliminate interceding pilot circuitry to simply and cost reduce applications with DC controls ...
