Key Features
- Model: SSR-40AA
- Quantity: 2 relays per pack
- Type: Single Phase AC-to-AC Solid State Relay
- Load Current: 40A
- Input Voltage Range: 70-280V AC
- Output Voltage Range: 24-480V AC
- Switching Method: Zero-Crossing
- Features a built-in LED status indicator
- Designed with a metal base plate for thermal management
Replaces / Cross-Reference Part Numbers
- SSR-40AA
- SSR 40AA
Compatibility & Fitment
- General-purpose component for applications requiring AC load switching.
- Commonly used in temperature control systems (PID), industrial automation, heating elements, lighting controls, and other machinery.
- Designed for use with resistive loads.
- Ensure your application's voltage and current requirements fall within this relay's specified operating range.
When to Replace
- The connected load does not turn on when control voltage is applied.
- The connected load remains on permanently, even with no control voltage.
- Operation is intermittent or unreliable.
- Visible signs of overheating, charring, or physical damage to the relay casing.
Installation Tips
- A heat sink is required for loads exceeding 10A to prevent overheating.
- Apply a thin layer of thermal compound between the relay's metal base and the heat sink for optimal heat transfer.
- Ensure all terminal connections are secure to prevent arcing.
- Use appropriately sized wiring to handle the intended load current.
- Verify correct wiring for input (control) and output (load) terminals before applying power.
