FAQs
CB1633T120208E7 is designed for top-feed, three-pole, three-wire configurations in industrial switchgear. Its 1600 A rating and 208 V main voltage align with common MCC and panelboard architectures. When pairing with a 120 V control circuit, ensure the control transformer and arc energy reduction relay are compatible with your protective relay scheme and CTs. Confirm clearance and mounting provisions match the 16 x 28 x 24 inch footprint and the 175 lb weight to maintain safe installation and service access.
This unit supports up to 1600 A continuous amperage with 208 V main voltage and 120 V control voltage, enabling single-device protection for heavy loads. The fusible configuration provides selective protection, while the arc energy reduction relay helps limit arcing, reducing damage and downtime. For best results, coordinate fuse ratings, CT ratios, and control wiring with your plant protection scheme and standards.
Yes. The product is UL Listed, indicating compliance with recognized electrical safety standards for control equipment in industrial environments. When deploying in a facility, verify that all panel enclosures, wiring methods, and protective relays also meet applicable local codes and the facility’s safety plan. The UL listing provides a solid baseline for procurement and QA audits.
The Arc Energy Reduction Relay reduces the energy released during fault and switching events, decreasing insulation stress and equipment wear. This translates to longer component life, fewer unplanned outages, and lower maintenance costs over the lifecycle of the switchgear. Combined with matched CTs, it also enhances protection accuracy and fault diagnostics, supporting faster problem resolution.
Plan CT connections and transformer integration carefully to maintain accurate current sensing and protective coordination. Use matched CTs as specified and route CT wiring cleanly to minimize noise. Confirm the top-feed, 16 in by 28 in by 24 in footprint fits the enclosure, and verify weight support (175 lb) plus safe handling during installation. Proper torque on connections and clearance from energized parts are essential for reliability.
