FAQs
For installation, note the rear terminals are included to simplify wiring in existing enclosures. The unit occupies a 629 mm depth, 365 mm height, and 387 mm width footprint, with a weight around 34.9 kg, requiring careful handling and compatible mounting provisions in switchgear or MCCs. Verify panel clearance and torque specs per Eaton guidelines and the accompanying datasheet.
Key specs include a frame 5, three‑pole construction, 1600 A current rating, 50 kA short‑circuit rating at 415 V, and Modbus RTU signaling via the LSIG trip unit (PXR20D) with relays. This combination supports high‑demand feeders and remote control or signaling within industrial networks.
Yes. The three‑pole design, Frame 5 construction, and high short‑circuit rating make it well suited for motor feeders and large‑load protection in manufacturing and processing facilities. Remote signaling via Modbus RTU enhances diagnostics and reduces downtime during motor faults or protection testing.
Compliances are listed as Contact Manufacturer, so confirm exact regulatory certifications with Eaton for your region and application. This ensures alignment with local standards (CE, IEC, or other), installation requirements, and safety processes prior to procurement and deployment.
Remote signaling and LSIG trip capabilities enable faster fault isolation and reduced maintenance windows, while the robust Frame 5, 1600A rating supports long service life under demanding loads. In retrofit projects, the rear terminals and defined footprint simplify installation, contributing to lower commissioning costs and improved overall return on investment.
