NA315 | Circuit Breaker | 15A | 3-Pole | 240V

Meet NA315, a robust industrial circuit breaker built for reliability in demanding electrical environments. This 15A, 3-pole device is designed for 240V three-phase systems, delivering dependable overcurrent protection for motors, conveyors, pumps, and other essential loads.

Precision protection for three-phase systems

The 3-pole configuration ensures coordinated protection across all three phases, reducing the risk of unbalanced currents that can damage equipment or cause downtime. With a 240V rating, it fits standard industrial panels and three-phase distribution boards.

Key specifications

• Amperage: 15A
• Poles: 3-Pole
• Voltage: 240V

Why choose NA315?

Designed for maintenance, retrofit, and replacement scenarios, NA315 provides a reliable upgrade path when a current-limiting or worn-out breaker needs replacement. The part number NA315 is the most reliable reference for compatibility, ensuring you’re selecting the exact fit for your panel and load profile.

Use cases and scenarios

• Maintenance: Replace aging or failed breakers to restore safe, continuous operation of three-phase equipment.
• Retrofit: Update legacy panels to accommodate modern loads while maintaining proper protection and trip coordination.
• Replacement: Quick swap-in for matching ratings in spare parts inventory, minimizing downtime.

Fit, ratings, and safety

Before you order, verify that the NA315 matches your panel’s acceptance list and your system’s 240V three-phase configuration. Given its 15A rating, ensure wiring and conductors are sized appropriately for the load, and that compatibility is confirmed by the part number reference.

Practical tips

• Keep a small stock of spare NA315s for proactive maintenance and faster downtime recovery.
• Document your panel’s part numbers and keep the NA315 as the go-to reference to avoid mix-ups during replacements.
• When retrofitting, review your motor starters and contactors to ensure coordinated protection with your new breaker.
