Industrial JKL3B350 350A 3-Pole 600 V Circuit Breaker

Meet the Industrial JKL3B350, a durable 3-pole circuit breaker engineered for demanding industrial power networks. With a robust 350 A current rating and a 600 V maximum, this unit is built to safeguard large three-phase feeders, motor drives, and heavy equipment from overloads and short circuits while maintaining reliable power flow.

Key specifications

• Part Number: JKL3B350
• Current rating: 350 A
• Poles: 3
• Voltage rating: 600 V

Why this Industrial Breaker stands out

The JKL3B350 is purpose-built for three-phase systems where stability and protection are non-negotiable. Its three-pole design ensures balanced interruption across all phases, helping to prevent phase imbalances and reducing the risk of equipment damage. The 350 A rating covers high-demand applications, while the 600 V rating supports a wide range of industrial power distributions, from manufacturing lines to heavy machinery feeders.

Ideal use cases

• Protecting large three-phase motors and conveyor systems in manufacturing facilities
• Guarding power distribution panels and motor control centers in industrial plants
• Providing reliable overload and fault protection for heavy equipment with substantial current draw

Practical benefits

• Clear part identification with the JKL3B350 model number for fast ordering and maintenance
• Consistent protection across all three phases, helping minimize downtime from electrical faults
• Suitable for environments where higher current handling and solid fault isolation are essential

Usage guidance

Designed for integration in standard industrial electrical distributions that operate up to 600 V. When selecting this breaker, ensure compatibility with your panel or switchgear and verify that the 350 A rating aligns with your maximum continuous operating current and protection needs. For optimal performance, pair with appropriate enclosures and follow all installation and safety guidelines relevant to high-current, three-phase equipment.
