FAQs
For installation, mount the unit in a suitable enclosure and connect the top-feed power wiring per the three-pole configuration. Use the 2NO-2NC contacts to interface with your control circuit and interlocks, ensuring the control power transformer is wired to provide stable control voltage. Always follow the UL Listed installation guidelines and verify NEMA 1, 3R, 4, or 12 compatibility with your panel.
CB3033T480KG7 is rated for 3000A with a 480V system voltage. It uses a three-pole configuration with 2 normally open and 2 normally closed contacts (2NO-2NC). The device supports fusible protection in a top-feed arrangement and includes a ground fault option with a control power transformer to power control circuits reliably.
Yes. The three-pole, 2NO-2NC contact arrangement supports robust safety interlock circuits, and the unit’s ground fault includes protective options. UL Listed certification and NEMA compatibility further ensure reliable operation in manufacturing environments, with options for auxiliary and interlock provisions to meet specific safety standards.
CB3033T480KG7 carries UL Listed certification and supports multiple enclosure ratings, including NEMA 1, NEMA 3R, NEMA 4, and NEMA 12. This enables safe installation in indoor, outdoor, and harsh environments while meeting regulatory and industry safety requirements for electrical switching devices.
With a durable three-pole design and integrated protection options, CB3033T480KG7 reduces spare-part needs and simplifies fault isolation. The included control power transformer and optional ground fault features help minimize downtime. Warranty terms (one year from installation or 18 months from shipment) support predictable maintenance budgeting and total cost of ownership optimization.
