The NF30-CB delivers reliable interruption of fault currents, helping to safeguard distribution panels and motor control centers from damage and downtime while supporting safe, predictable startup and shutdown sequences.

• Current rating: 5A
• Poles: 3-Pole
• Breaker type: Circuit Breaker
• Applications: panelboards, switchboards, and control panels; ideal for distribution panels and motor control centers

Why this 3-Pole design matters

A three-pole configuration is well-suited for protecting three-phase loads common in motors, pumps, and automated equipment. The NF30-CB fits neatly into three-phase distribution schemes, enabling comprehensive protection for all phases from a single, compact device.

Ideal use cases

• New installations in industrial or commercial control panels where reliable three-phase protection is required
• Retrofits or replacements in existing panelboards and motor control centers to restore dependable overcurrent protection
• OEM equipment builds where compact, straightforward protection is essential for compact panel layouts

What sets the NF30-CB apart

Rather than a one-size-fits-all solution, the NF30-CB is purpose-fit for three-phase networks that demand precise, dependable protection. Its 5A rating is ideal for protecting smaller or pilot circuits within larger systems, while its Mitsubishi heritage offers compatibility and consistency with other components in your control architecture.

Practical tips for installation and setup

• Verify panel compatibility to ensure proper fit and safe operation within your distribution panel or motor control center
• Follow standard electrical safety practices and local codes during installation and maintenance
• Schedule regular inspections to confirm clean contacts and reliable trip performance over time
