NN622900 | Circuit Breaker | 900A | 2-Pole | 600V

The NN622900 Circuit Breaker is an industrial-grade protection device designed for demanding electrical panels where reliability and precise specifications matter. With a 900 A rating across two poles operating at 600 V, this unit provides robust protection for high-current feeders and essential equipment, helping you minimize downtime and safeguard your system.

Key specifications

• Amperage: 900 A
• Poles: 2-Pole
• Voltage rating: 600 V
• Part reference: NN622900

Why this matters for your system

In industrial environments, outlets, motors, and feeders draw substantial current. A two-pole circuit breaker with a 600 V rating ensures both conductors are simultaneously protected and disconnected when an overcurrent or fault occurs. The NN622900 is built to withstand the rigors of maintenance, retrofit, and replacement projects, offering a dependable path to fast, safe isolation of circuits during servicing and emergencies.

Ideal use scenarios

• Maintenance shutdowns and panel servicing where a matching 2-pole, 600 V protection device is required
• Retrofit projects upgrading legacy systems to a modern, compliant protection solution
• Replacement of worn or obsolete breakers in industrial control panels needing a 900 A, 2-pole device

Compatibility and ordering guidance

To ensure proper fit and ratings, verify the panel compatibility with the NN622900 part number. As the best reference for compatibility, this exact part number streamlines procurement and reduces the risk of mismatched specifications. Before placing an order, double-check that your panel, bus configuration, and interrupt requirements align with a 900 A, 2-pole, 600 V device.

Practical tips for installation and use

• Use the NN622900 in applications that demand simultaneous disconnect of both hot legs for complete circuit safety.
• When retrofitting, compare panel model and existing breaker type to confirm a clean fit and secure mounting.
• Maintain a documentation trail showing the part number (NN622900) and ratings to simplify future replacements or audits.
