Replaces / Cross-Reference Part Numbers

• Directly replaces parts marked with SSR-25AA
• Interchangeable with other single-phase AC-to-AC solid state relays with matching 25A current, input voltage, and output voltage specifications

Compatibility & Fitment

• Industrial automation equipment
• Temperature control systems for heaters and ovens
• Motor and lighting control circuits
• Programmable logic controller (PLC) interfacing
• Projects requiring silent, high-speed switching of AC loads

When to Replace

• The relay fails to activate the load when control voltage is applied.
• The load remains constantly on, even with no control voltage.
• Operation is intermittent or unreliable.
• Visible signs of physical damage, such as cracks, burns, or melted housing.

Installation Tips

• A heat sink is recommended for loads exceeding 10A to prevent overheating and ensure reliable operation.
• Apply a thin layer of thermal compound between the relay's metal base and the heat sink for optimal heat transfer.
• Ensure correct wiring: connect control voltage to the input terminals and the load circuit to the output terminals.
• Verify your circuit's voltage and current do not exceed the relay's maximum ratings.
