ITE | CL3B300 | Circuit Breaker | 300A | 3-Pole | 600V | Bolt-On

Meet the ITE CL3B300 Circuit Breaker — a purpose-built 3-pole protection device designed for demanding 600V systems. This 300A unit uses a bolt-on mounting, delivering a secure, vibration-resistant connection ideal for maintenance, retrofit, and replacement projects where exact specifications matter.

Key specifications at a glance

• Amperage: 300A
• Poles: 3-Pole
• Voltage: 600V
• Mounting: Bolt-On

The CL3B300 is specifically suited for three-phase electrical environments where reliable, high-current protection is essential. Its bolt-on construction provides a robust mechanical hold and solid electrical contact, helping minimize connection issues that can arise with other mounting styles.

Why this breaker stands out

• The part number CL3B300 is your best reference for matching equipment, ensuring you don’t gamble on fit during maintenance or upgrades.
• Strong for retrofits and replacements: If you’re upgrading or replacing a worn-out unit in a 600V distribution panel, this 3-Pole, 300A breaker is designed to slot into panels that require the same specs.
• Clear identification for planning: With explicit amperage, pole count, voltage, and mounting style, you can quickly validate suitability in job briefs, BOMs, and service orders.

Ideal use scenarios

• Maintenance of existing 3-phase, 600V distribution panels where a 300A rating is required
• Retrofit projects to upgrade panel protection without altering bus bar configuration
• Replacement of aged or failed units in commercial, industrial, or facilities environments that rely on stable, high-current interruption

Practical considerations

• Before ordering: Confirm fit and ratings against your panel’s documentation. The CL3B300 is the definitive reference for compatibility in this spec set.
• Installation note: Ensure the system is fully de-energized and installed by a qualified electrician, given the 600V operating environment and 300A current level.

Whether you’re performing routine maintenance, executing a retrofit, or replacing a critical component, the ITE CL3B300 Circuit Breaker delivers dependable three-phase protection with a bolt-on mount that supports secure, long-term performance in 600V service.
