Industrial E3015 15A 3-Pole 240 V Circuit Breaker

Meet the Industrial E3015 15A 3-Pole 240 V Circuit Breaker—the rugged, reliable protector designed for demanding three-phase panels. With a 15 A current rating and a 240 V operating voltage, this unit is built to safeguard three-phase distribution lines, reducing downtime and protecting wiring, sensors, and motors in tough industrial environments.

Designed around a responsive thermal-magnetic trip mechanism, the E3015 delivers fast, precise protection against overloads and short circuits. This means fewer nuisance trips and more consistent operation for your three-phase equipment, helping extend equipment life and maintain steady production.

Key specifications

• Current rating: 15 A
• Poles: 3 (three-pole)
• Voltage rating: 240 V
• Part number: E3015

Why the E3015 is the right choice for your panel

This three-pole design is purpose-built for industrial control panels, switchgear, and distribution boards that power motors, conveyors, and other three-phase equipment. The 240 V rating aligns with common North American and international 3-phase distribution layouts, delivering reliable protection without oversizing the breaker or complicating panel design.

Real-world use cases

• Protecting a three-phase motor-driven conveyor on a manufacturing line up to 15 A per phase
• Guarding control panels for CNC machines, pumps, and fans that require clean, phase-balanced protection
• Providing clear, per-phase protection in small to mid-size switchgear and distribution assemblies

Practical deployment tips

• Install the E3015 at the source of a three-phase circuit to prevent wiring damage and reduce fault propagation
• Label each phase clearly and document typical trip characteristics to streamline fault diagnosis
• Include routine trip testing in your maintenance plan to verify reliable performance when it matters most

The Industrial E3015 15A 3-Pole 240 V Circuit Breaker is a precise, dependable component for safeguarding your critical three-phase infrastructure. Its combination of robust protection, practical three-pole design, and a compact footprint makes it an indispensable part of industrial panels, control cabinets, and switchgear where reliable trip protection and clear phase separation are essential.
