ABB | S3N030TW | Circuit Breaker | 30A | 3-Pole | 600V | 25kA | Bolt-On

Meet the ABB S3N030TW Circuit Breaker—a bolt-on, three-pole protection device designed for demanding 600V industrial and commercial systems. With a 30A rating and a 25kA interrupt capacity, this breaker is built to safely interrupt fault currents while keeping critical machinery protected and downtime to a minimum. Its bolt-on mounting provides a secure, durable connection in panels that require robust, fixed hardware.

• Amperage: 30A
• Poles: 3-Pole
• Voltage: 600V
• Interrupt rating: 25kA
• Mounting: Bolt-On
• Part reference: S3N030TW (ABB)

This breaker is purpose-built for maintenance, retrofit, and replacement projects where exact specifications are critical. Its three-pole design ensures synchronized protection across all phases, making it ideal for multi-line motors, pumps, and other three-phase loads common in warehouses, manufacturing floors, and HVAC systems. When you’re upgrading or renewing panel protection, the S3N030TW delivers reliable tripping performance aligned with industrial standards.

Why choose this bolt-on solution over alternatives? The bolt-on configuration provides a physically secure attachment that resists loosening under vibration, which is essential in busy electrical rooms and equipment cabinets. The 25kA interrupt capacity is suitable for higher fault currents often encountered in industrial environments, giving you an extra margin of safety and reliability during fault events.

Who is this ideal for? Maintenance teams and electricians outfitting or retrofitting 3-phase distribution panels, electrical contractors performing panel upgrades, and facility engineers looking for a precise match to existing S3N030TW specs or equivalent configurations.

Practical usage tips: - Verify panel compatibility and mounting provisions before ordering; the S3N030TW is a bolt-on device designed for specific enclosure families. - Confirm the exact fault current level in your installation to ensure the 25kA interrupt rating provides adequate protection. - Keep a spare, keyed replacement on hand to minimize downtime during maintenance windows. - Follow your panel manufacturer’s torque and installation guidelines to ensure secure, code-compliant mounting.

For reliable three-phase protection that aligns with ABB standards, the S3N030TW is a precise, purpose-built choice. Confirm fit and ratings with your panel documentation, and reference the S3N030TW part number to ensure compatibility across your electrical system.
