Specifications

• Amperage: 40 A
• Voltage: 277 V
• Mounting: Bolt-On

Ideal use cases

• Maintenance tasks for legacy panels where a precise 40 A/277 V protection is required.
• Retrofits that convert circuits to higher ratings or update protection without replacing the entire enclosure.
• Replacement scenarios where the existing bolt-on breaker matches the NEF214040 form factor and electrical characteristics.

What sets it apart

• Part-number driven compatibility: using NEF214040 as the primary reference reduces the risk of mismatched breakers during procurement.
• Bolt-On simplicity: faster installation with straightforward mounting, helping minimize panel downtime during critical repairs or upgrades.
• 277V capability: well-suited for commercial and industrial power distribution, especially in lighting, feeders, and equipment circuits commonly run at higher voltages.

Buying and installation tips

Before purchasing, verify that your panel accepts bolt-on protection devices and that 40 A at 277 V aligns with the protected load. Always follow your site’s electrical safety practices and manufacturer guidance. Keep a spare protective device on hand for critical circuits, and ensure any installation is performed by a qualified technician to maintain compliance with electrical codes.
