Crydom A53TP50D 3-Phase Solid State Relay 48–530VAC 50A 90–280VAC Input New
Crydom A53TP50D 3-Phase Solid State Relay 48–530VAC 50A 90–280VAC Input New
Lav lagerbeholdning: 1 tilbage
-
Brand: Crydom / Sensata.
-
Model: A53TP50D (53TP series three‑phase SSR, panel mount).
-
Condition: New, never used, from old stock. Unit is unused and clean; original cardboard box shows heavy storage wear, discoloration and writing but still protects the relay.
Technical specifications
-
Function: 3‑phase solid state relay, 3 Form A (3PST-NO) thyristor/SCR output.
-
Load voltage: 48–530 V AC, 47–63 Hz.
-
Load current: Up to 50 A per phase with proper heat sinking.
-
Control/input voltage: 90–280 V AC, zero‑crossing turn‑on.
-
Input current: Approx. 2.2–10 mA over rated control range.
-
Transient overvoltage: up to about 1200 V peak (internal overvoltage protection).
-
Operating temperature: approximately −40 °C to +80 °C (with suitable heatsink).
-
IP rating: IP00 open-frame, panel-mount “hockey puck” module with screw terminals (A1–C1 / A2–C2).
-
Agency approvals: CE, cURus and other safety approvals typical for the 53TP series (markings on relay body).
Main features and use
-
Three‑phase AC solid state relay for switching heaters, motors, and other industrial loads where fast, silent and maintenance‑free switching is desired.
-
Zero‑cross switching reduces electrical noise and inrush stress on loads, improving reliability in automation systems.
-
Direct‑bond copper substrate and robust screw terminals provide low thermal resistance and secure wiring for demanding environments.
-
Ideal for OEMs, repair shops, and maintenance engineers needing a drop‑in replacement for existing Crydom A53TP50D or compatible 3‑phase SSRs.
