DR45 Series

The DR45 Series Solid State Relay (SSR) from Sensata Crydom offers a high performance solution for controlling AC loads in industrial environments. This compact SSR, measuring 45mm in width, offers output ratings of up to 60 Amps at 600 VAC, making it ideal for challenging applications like heating, lighting, and motor control. Its durable design features built-in overvoltage protection and high I²t capability, ensuring enhanced reliability and performance in motor starting and pump control. 

One of the key advantages of the DR45 SSR is its ease of installation. It features large cage clamp terminals that can accept wire sizes up to 3 AWG, reducing the need for additional accessories. The integral heat sink eliminates the need for complex thermal calculations, and the SSR can be mounted on a DIN rail or directly onto a panel. This versatility in mounting options allows for quick and efficient installation, reducing labour costs and minimising downtime. 

The DR45 SSR is also safety focused, with its IP20 touch-safe housing and approvals from UL and VDE. It is designed for long-term operation in industrial applications such as plastic injection moulding, HVAC systems, and railway vehicles. Its contactor configuration ensures robust performance, even under heavy loads, while maintaining a compact form factor that saves valuable space in control panels. 

Available with both AC and DC control voltage options, the DR45 SSR provides flexibility for various system requirements. Its instant-on and zero-voltage switching options make it suitable for both general use and motor control applications, where precise operation is crucial.
