EC3030L | Circuit Breaker | 30A | 3-Pole | 240V

EC3030L is a rugged industrial circuit breaker engineered to protect three‑phase electrical systems with precision and reliability. This 30A, 3‑pole, 240V unit is designed for maintenance, retrofit, and replacement projects where exact specifications matter, delivering consistent performance in demanding environments.

Key specifications

• Amperage: 30A
• Poles: 3‑Pole
• Voltage: 240V
• Part number: EC3030L

Why this 3‑pole design matters

Triple‑pole construction provides synchronized protection across all three phases, reducing the risk of phase imbalances and protecting motors and equipment from damaging overcurrents. The EC3030L is particularly well suited for panels that require coordinated disconnection of all conductors, improving safety and reliability during faults or maintenance.

Ideal use cases

• Industrial panels and switchgear where three‑phase protection is required
• Retrofit projects replacing aging breakers with a compatible, clearly identified part
• Maintenance and replacement in manufacturing lines, HVAC systems, and motor control centers

Installation and compatibility

Notes: Confirm fit and ratings before ordering. The EC3030L part number is the best reference for compatibility. Before installation, verify that your panel labeling matches 30A, 240V, 3‑pole specifications and that the breaker’s footprint aligns with your enclosure’s busbar configuration. For safety and performance, rely on qualified personnel to perform the installation and follow all local electrical codes.

Practical tips for maximum longevity

• Schedule routine inspections to check for signs of wear, corrosion, or wiring looseness around terminals
• Keep the breaker’s enclosure clean and free from dust and moisture to maintain reliable tripping performance
• Torque connections according to the panel manufacturer’s guidelines to maintain secure electrical contact
• Use the part number (EC3030L) as your reference when ordering replacements or spare units to guarantee exact compatibility

Whether you’re restoring an industrial line, upgrading an aging panel, or performing targeted replacements, EC3030L delivers dependable three‑pole protection at 240V. Its straightforward specification set—30A, 3‑Pole, 240V—speaks directly to real‑world needs, helping you keep systems running smoothly with minimal downtime.
