Product Description

The SCHNEIDER Solid State Relay: Surface Mounted (SKU 55WT12, 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.

Used in

Common applications for SCHNEIDER
Motor starting in conveyor systems — Schneider Altistart ATS 22 soft starters (e.g., ATS22D17S6U) reduce inrush current.
Speed control for industrial pumps — Schneider Altivar ATV320 VFDs (e.g., ATV320U55N4W) provide variable flow regulation.
Machine safety interlocking — Schneider XPSUAF13AP safety relays monitor emergency stop circuits on assembly lines.
Panel-mounted control stations — Schneider XB5 flush push buttons (ZB5AA5) serve as start/stop operators in MCCs.
Heavy-duty motor switching — Schneider LC1G150LSEA contactors handle 150 A loads in compressor and crusher applications.
Emergency stop actuation — Schneider 9001K mushroom-head push buttons (9001KR25R) provide red, momentary stop functions.
