Product Description

The SCHNEIDER Solid State Relay: Surface Mounted (SKU SSP1A450M7, MPN SSP1A450M7) is a panel-mounted, AC-output relay with a maximum output current of 50 A and an output voltage range of 48 to 660V AC. It features a screw clamp electrical connection, is finger safe, and has an input current of 5 to 10 mA. The relay uses SCR technology and is not recommended for operation without a heat sink.

Frequently Asked Questions

What is the SCHNEIDER SSP1A450M7 solid state relay used for?

The SCHNEIDER SSP1A450M7 solid state relay is used for switching AC loads in industrial automation and process control applications. It is suitable for panel-mounted installations where reliable, silent switching of up to 50 A at 48 to 660V AC is required, such as in heating, lighting, and motor control systems.

What are the specifications of the SCHNEIDER SSP1A450M7 solid state relay?

The SCHNEIDER SSP1A450M7 is a panel-mounted, AC-output solid state relay with a maximum output current of 50 A and an output voltage range of 48 to 660V AC. It uses SCR technology, has a screw clamp connection, is finger safe, and requires an input current of 5 to 10 mA. Operation without a heat sink is not recommended.

Where to buy the SCHNEIDER SSP1A450M7 solid state relay worldwide?
