E3040 | Circuit Breaker | 40A | 3-Pole | 240V

The E3040 circuit breaker is a purpose-built industrial solution for protection in three-phase electrical systems. Rated at 40A and designed for 240V operation, this 3-Pole unit is ideal for maintenance, retrofit, and replacement projects where exact specifications matter. If your equipment, control panels, or machine wiring require a precise 40A, 3-Pole, 240V breaker, the E3040 is engineered to meet those needs with reliability and straightforward interchangeability.

Key Specifications

• Amperage: 40A
• Poles: 3-Pole
• Voltage: 240V
• Series/Use: Industrial circuit protection for maintenance, retrofit, and replacement projects

Why the E3040 Stands Out for Industrial Protection

When you’re safeguarding three-phase equipment, the E3040 delivers a precise fit that aligns with your existing infrastructure. The three-pole design ensures balanced protection across all three phases, which is essential for motors, drives, and other industrial loads that rely on consistent phase protection. This breaker is particularly well-suited for scenarios where a straightforward, exact-spec replacement is required—reducing downtime and ensuring continued compatibility with your electrical panels.

Ideal Use Cases

• Replacing worn or tripped breakers in three-phase panelboards within manufacturing floors, warehouses, and plant automation setups.
• Retrofit projects where equipment specifications call for a 40A, 3-Pole, 240V protective device.
• Maintenance plans for CNC machines, conveyors, and motor-driven equipment that operate on 240V three-phase power.
• New installations in control panels that require a reliable, exact-spec circuit protector to match existing wiring and safety standards.

Compatibility and Ordering Guidance

For seamless compatibility, reference the part number E3040. This exact identifier is the best reference to ensure the breaker will fit your enclosure, bus connections, and overall protection strategy. Before ordering, confirm that the device matches your system’s voltage (240V) and current rating (40A) and that the overall panel design accommodates a 3-Pole configuration.

Installation and Practical Tips

• Always de-energize and lock out the circuit before removing or installing the breaker.
• Verify that your panel and wiring are rated for 240V and that a 40A protection level aligns with the connected loads.
• Check that the incoming and outgoing conductors fit the breaker terminals and that there’s no signs of wear or damage in the surrounding panel.
• Keep the part number (E3040) handy during maintenance cycles to simplify future replacements and warranty checks.

With the E3040, you gain a targeted, dependable solution for three-phase protection that aligns with industrial maintenance, retrofit, and replacement workflows. Its specifications—40A, 3-Pole, 240V—are not just numbers: they define a protective device that keeps critical machinery running smoothly while simplifying lifecycle management in demanding environments.
