It's the piece that decides when to pull in and when to drop out, and it's rated for the specific control voltage you feed it: 48 V AC or 48...72 V DC. That dual-range DC capability is handy on a line where the control bus might sag a bit — it holds in down to 38.5 V on the DC side before dropping out at 29 V. This unit plugs onto the front face of the contactor base. The 48 V AC / 48-72 V DC control voltage is the key spec. It's listed for utilisation categories AC-41, AC-43, and AC-44 — that covers resistive, motor, and lightly inductive loads in the control circuit. The IP20 front-panel protection is standard for enclosed gear; the IP40 rating on the front face outside the connection zone means it's fine behind a panel door but not for washdown areas. The TeSys Ultra LUCL1XES is specifically intended for motor control and motor protection applications, with a particular focus on protecting variable-speed drives and soft-start/soft-stop units. In practice, you'll find it in motor control centres (MCCs) and individual starter buckets where the control voltage is 48 V — common in industrial plants that use a 48 V DC control bus for reliability. The plug-in front-face mounting means it swaps without disturbing the power wiring, which matters when a line-down replacement has to happen fast.","metaTitle":"Schneider TeSys Ultra LUCL1XES Magnetic Control Unit","metaDescription":"Schneider Electric TeSys Ultra LUCL1XES magnetic control unit for motor protection. 48V AC/48-72V DC control circuit.
