Crydom / Sensata DR45 Solid State Relays

Crydom/Sensata DR45 Solid State Relays (SSRs) are powerful and compact SSRs in a DIN-rail 45mm wide package with an output rating up to 60A at +40°C. These relays from Crydom/Sensata offer mounting flexibility on a panel or DIN rail and convenient input connection options. The DR45 SSR contactor configuration and large cage clamp terminals allow connecting wires up to 3AWG size on the output without the use of any additional accessories. This makes them truly ready-to-use devices and therefore reduces installation cost and time. The high I2t capability and optional built-in Over Voltage Protection (OVP) make it suitable for demanding heating, motion, and lighting applications.
