EA3040 | Circuit Breaker | 40A | 3-Pole | 240V | Bolt-On

Meet the EA3040, a purpose-built industrial circuit breaker designed for robust protection in 240V, 3-pole electrical systems. With a precise 40A rating and bolt-on mounting, this component is engineered for reliable service in maintenance, retrofit, and replacement projects where exact compatibility matters.

Key specifications

• Amperage: 40A
• Poles: 3-Pole
• Voltage: 240V
• Mounting: Bolt-On
• Part number: EA3040

Why choose the EA3040

In industrial panels, dependable overcurrent protection is essential. The EA3040 delivers a solid, bolt-on installation experience that stays secure in demanding environments. Its 3-pole configuration is ideal for protecting multi-phase feeders and protecting circuits that require coordinated shutdown across phases, enhancing safety and system integrity.

Ideal use cases

• Maintenance work on existing 3-phase, 240V circuits that use bolt-on breakers
• Retrofit projects where replacing an older unit with the same specifications minimizes downtime
• Replacement needs for panels and enclosures that specify the EA3040 part number for compatibility
• Spare parts strategy for service fleets that keep critical 240V, 3-pole protection on hand

How to ensure a perfect fit

Always confirm fit and ratings before ordering. The EA3040 is the best reference when matching breakers to compatible panels and bus designs. If you’re updating an existing installation, verify that the panel expects a 3-Pole, 240V bolt-on device with a 40A rating and that the mounting hardware aligns with your enclosure.

Practical guidance for installation and maintenance

• Disconnect power and verify zero-voltage conditions before handling the breaker.
• Ensure panel compatibility by cross-referencing the part number EA3040 with your enclosure’s specification sheet.
• Use the dedicated bolt-on hardware and torque settings recommended for your panel to maintain secure mounting.
• Periodically inspect the device during routine maintenance for signs of wear, overheating, or loose connections.

With the EA3040, you gain a reliable, industry-ready solution that aligns precisely with your 40A, 3-pole, 240V bolt-on requirements—delivering peace of mind through consistent protection and straightforward installation in demanding environments.
