• Practical replacement option: When upgrading or refreshing protection in established switchgear, this model aligns with ABB’s protection philosophy to minimize downtime and maintain system integrity.
• Durable for harsh environments: Engineered for consistent performance in industrial settings, helping reduce nuisance trips and extend service life under demanding conditions.

Use cases and installation considerations

• Motor control and power distribution in manufacturing floors, processing lines, and automation cells.
• Feeder protection for industrial panels and switchgear where a 3-pole, 600 V device is required.
• Maintenance replacements that need to mirror the existing protection profile without compromising system safety.

How this model compares and what to check

• Ideal for setups needing three-phase protection with a 100 A rating, offering a balance between protection scope and current capacity for mid-sized industrial loads.
• Important: Confirm fit by part number and application requirements before purchasing. If you’re unsure about compatibility, consult with a specialist using the exact panel or gear model.

Practical tips for ordering and lifecycle management

• Keep the exact part number handy during ordering to ensure the correct configuration and interrupting rating for your system.
• Document your installation context (voltage, current, pole count) and the equipment it protects to streamline future maintenance or replacements.
• Store replacements in a clean, dry area and inspect the device for transit damage before installation to avoid delays.
