Titus HVAC CCT-150 50 Amp Solid State Relay

The Titus HVAC CCT-150 is a heavy-duty 50 amp solid state relay (SSR) designed for demanding HVAC and industrial control applications. This panel-mount relay serves as a direct replacement for the Carlo Gavazzi RM1A60D50S333, offering reliable switching performance without the mechanical wear associated with traditional electromechanical relays.

Key Features:

• 50 amp continuous current rating at 40°C ambient temperature
• Wide operating voltage range of 42-660 VAC for versatile applications
• Zero-crossing switching technology minimizes electrical noise and extends load life
• Low voltage DC control input (4-32 VDC) with LED status indicator
• Built-in overvoltage protection (MOV) safeguards against voltage spikes
• Back-to-back SCR output design reduces power dissipation and improves surge current handling
• Panel mount configuration with IP20 protective cover
• Optical isolation exceeds 4000 VAC for enhanced safety

Solid state relays offer superior reliability compared to mechanical relays by eliminating moving parts that can wear out over time. The CCT-150's zero-crossing switching waits for the AC waveform to pass through zero voltage before switching, which reduces electromagnetic interference and protects sensitive loads. Suitable for resistive, inductive, and capacitive loads in HVAC systems, industrial equipment, and automation applications. Heat sink installation recommended for continuous high-current operation.
