EC3020L | Circuit Breaker | 20A | 3-Pole | 240V | Bolt-On

Meet the EC3020L, a rugged industrial circuit breaker designed for maintenance, retrofit, and replacement tasks where exact specifications matter. This 20A, 3-pole unit operates at 240V and features bolt-on mounting for fast, field-ready installation.

Core specifications

• Amperage: 20 A
• Poles: 3-Pole
• Voltage: 240 V
• Mounting: Bolt-On

The EC3020L is tailored for three-phase electrical systems where reliable, coordinated disconnection across all live conductors is essential. By matching the exact part number, technicians ensure compatibility with existing panels, bus stabs, and bus bars, minimizing downtime during swaps or retrofits.

What makes the EC3020L stand out

Unlike generic replacements, this unit delivers precise 20A, 3-pole, 240V protection in a bolt-on design, enabling quick field installation with fewer wiring complications. Its three-pole construction provides consistent protection across all phases, reducing the risk of uneven load or partial faults after a trip.

Ideal applications

• Maintenance on industrial machines powered by 3-phase 240V systems
• Retrofit projects where upgrading or replacing aging breakers with exact EC3020L specs is required
• Panel replacements or upgrades in control rooms, manufacturing lines, or electrical rooms

Compatibility and ordering tips

Before ordering, confirm fit and ratings. The EC3020L part number is the best reference for compatibility, ensuring the breaker matches your panel, bus, and trip requirements. If you're replacing a failed breaker, verify the replacement matches the existing 3-pole, 240V, 20A configuration to maintain proper system protection and trip coordination.

Practical notes

Bolt-on installations involve direct mounting to the panel; ensure proper mounting hardware torque and isolation from live components. If you’re working with an older enclosure, verify that bolt-on breakers are compatible with your panel design to ensure safe, reliable operation.
