Selling Policy 25-000 - Distribution and Control Products and Services
High-current capability with robust protection is a core feature of the CB2533T120480KA95, rated for 2500A and 480V system voltage. This enables a single switch to handle large power loads, reducing panel count and improving overall maintenance efficiency. The business impact is fewer components in the field and faster commissioning, which translates to reduced downtime in critical production lines and safer rehabilitation of powered equipment. The three-pole, 1NO-1NC configuration simplifies wiring and provides reliable control for complex motor and line-start applications, making it ideal for distribution centers and heavy machinery environments where space and safety matter. The top feed and fusible design streamline installation in existing switchgear footprints, lowering installation risk and enabling easier serviceability during revisions. With UL Listed and NEMA 1, 3R, 4, 12 compatibility, this unit stands up to dust, moisture, and varying ambient conditions, supporting long-term lifecycle costs while maintaining regulatory compliance. Optional ground-fault relay, auxiliary contacts, and Kirk/Aux provisions give installations the flexibility to meet evolving safety standards without replacing the switch.
