The CAD50AW7 is a TeSys Deca control relay from Schneider Electric's TeSys range, built for switching control circuits in industrial panels. It carries 5 normally-open (NO) poles and is rated for utilisation categories AC-15, AC-14, and DC-13 per EN/IEC 60947-5-1 — meaning it handles solenoid and electromagnetic loads common in contactor coils, relays, and small valve actuators. The 5 NO contact arrangement is typical for extending control outputs in a motor starter or safety circuit without adding a second relay.
The utilisation category tells you the load type this relay is certified to switch. AC-15 covers inductive loads above 72 VA (contactor coils, solenoid valves); AC-14 covers electromagnetic loads below 72 VA; DC-13 covers solenoids and contactors on DC control circuits. If your BOM calls for switching a 277 V AC contactor coil, the 277 V AC standard coil on this unit matches directly — no separate coil voltage variant to order. The 5 NO pole count gives you five independent switching channels in one 45 mm wide package, saving DIN-rail space compared to stacking individual relays. Physical fit: 93 mm depth, 45 mm width, 107 mm height. That 93 mm depth is the key dimension for enclosure clearance — most 120 mm deep enclosures leave 27 mm for wiring behind the relay. The snap-in terminals (listed as part of the description) mean the relay clips directly onto the DIN rail without screws, speeding panel assembly and replacement.
Where it goes — panel integration
The IP2X front-face protection (per VDE 0106) means the front is finger-safe — no live parts accessible from the front when the panel door is open. The TH protective treatment (conforming to IEC 60068) adds tropicalisation against humidity and corrosion, which matters for panels in non-conditioned environments or near washdown zones. Operating temperature spans -40 to 60 °C, with derating allowed up to 70 °C — sufficient for most indoor industrial enclosures without forced cooling.
