UBW 2500 A Frame Molded-Case Circuit Breakers

The UBW2500 family tops the UBW line for high-capacity feeders and mains. These breakers use an electronic trip platform for precise, repeatable protection and are offered with or without Maintenance Mode to help reduce arc-flash incident energy during service.

Where they fit

• Applications: switchboards, large panelboards, service entrance and feeder mains, high-horsepower MCC feeders.
• Environments: commercial campuses, hospitals, data centers, industrial plants.

Ratings & options (480 VAC kAIC)

• Interrupting classes:
  • H — up to 65 kA
  • L — up to 100 kA
• Ampere settings: 1600, 2000, 2500 A (3-pole).
• Trip type: Electronic (no lugs supplied per datasheet).
• Maintenance Mode (ELSI variants): enables a safer, low-incident-energy setting for energized work.

Examples

• Standard electronic trip: UBW2500H-ELS1600-3A, UBW2500L-ELS2500-3A
• With Maintenance Mode: UBW2500H-ELSI2000-3A, UBW2500L-ELSI2500-3A

Why UBW2500

• Right-sized interruption: H/L options let you match available fault current without overspec’ing.
• Electronic precision: stable, adjustable protection curves for better coordination.
• Service safety: Maintenance Mode option helps reduce arc-flash energy during commissioning or maintenance.
• Consistent form factor: aligns with the broader UBW family for easier standardization.
