Industrial EA3100N 100A 3-Pole 240 V Circuit Breaker

Industrial EA3100N 100A 3-Pole 240 V Circuit Breaker is the dependable shield for three-phase power systems in demanding industrial environments. This rugged device delivers precise overcurrent protection, safeguarding wiring, motors, and equipment while helping you maintain uptime on busy production floors.

Designed to protect all three phases simultaneously, the EA3100N trips across all poles when faults occur, preventing dangerous phase-to-phase faults and uneven loading. With a 100 A current rating and a 240 V operating range, it’s built to handle the common loads found in manufacturing, processing, and heavy-duty automation setups.

Why the EA3100N stands out

• Three-pole protection ensures synchronized interruption of all phases, reducing the risk of equipment damage from unbalanced faults.
• 100 A rating provides robust protection for demanding motors, pumps, and conveyors without nuisance tripping in normal operation.
• Compatibility and traceability by part number EA3100N makes sourcing, stocking, and replacing straightforward in established panels and service programs.
• Industrial-grade reliability designed for continuous operation in tough environments where consistent protection is required.

Ideal use cases

• Protection for three-phase motors powering conveyors, fans, pumps, and CNC machines in manufacturing facilities.
• Power distribution feeders in panel boards that supply 240 V systems to industrial equipment and processing lines.
• Replacement or spare part for existing EA3100N installations to minimize downtime during maintenance.

What problems it solves

• Prevents motor burnout and wiring damage by cutting power quickly at fault currents across all three phases.
• Reduces unplanned downtime by providing reliable, predictable tripping behavior in everyday operation.
• Enhances safety and control in multi-phase power setups, helping maintain stable production conditions.
