RM1A48D50 single-phase solid-state relay
Technical Specifications

• Load Current Rating: 50 A max
• Operating Voltage Range: 42 to 440 V AC (800 Vp peak)
• Control (Input) Voltage Range: 4 to 32 V DC
• Switching Mode: Zero-cross switching (switches at zero voltage to minimize grid interference)
• Contact Configuration: SPST-NO (Single Pole Single Throw, Normally Open)
• Protection Rating: IP20 (with clip-on protective cover)
• Dimensions: 58.2 x 44.8 x 28.8 mm 

Key Features

• Built-in varistor for transient/overvoltage protection in heavy industrial environments.
• Utilizes Direct Copper Bonding (DCB) technology for enhanced thermal performance.
• Compatible with resistive, inductive, and capacitive loads.
• Integrated LED status indicator for the control input. 

Could you tell me what type of load (resistive heater, motor, or other inductive load) you plan to connect, so I can advise if you need an external heatsink or specific fusing?
