• Part of Siemens' trusted protection lineup, ensuring compatibility with existing Siemens panel boards and feeders when the part number E43B060 is referenced.

Ideal use scenarios

• Replacing a damaged or degraded 60A, 3-pole breaker in a 480V distribution panel.
• Retrofit projects where a Siemens-equivalent spec is required to maintain protective coordination and trip characteristics.
• Motor control circuits in manufacturing, processing, or data-center environments where reliable interruption performance matters.

Important fitment note

Before ordering, confirm the fit and ratings. The E43B060 part number is the best reference for compatibility with your panel or bus arrangement.

Practical guidelines for safe, effective installation

• Ensure the main power is de-energized and lockout/tagout procedures are followed before replacing any breaker.
• Verify that the panel labeling and coordination align with a 60A, 3-pole, 480V device with an 18kA rating.
• Adhere to local electrical codes and manufacturer torque specifications for bolt-on installations to maintain protective integrity.
