Industrial LAB3350V 350A 3-Pole 3350 V Circuit Breaker

Industrial LAB3350V 350A 3-Pole 3350 V Circuit Breaker is a purpose-built protective device for demanding high-voltage power distribution. With a 3350 V voltage rating and a solid 350 A current rating across three poles, this breaker delivers reliable, coordinated protection for feeders, motors, and switchgear in heavy industrial environments. Part number LAB3350V ensures precise cataloging and compatibility within your existing electrical infrastructure.

Key specifications

• Current rating: 350 A
• Poles: 3
• Voltage rating: 3350 V
• Part number: LAB3350V

Ideal use cases

• High-voltage industrial feeders in manufacturing plants, processing facilities, and large facilities
• Motor control centers and distribution panels that require three-pole, simultaneous phase protection
• Switchgear assemblies where a single device must reliably interrupt fault currents across all three phases

What makes this breaker unique

• High-voltage capability (3350 V) paired with a substantial 350 A current rating, enabling protection for robust industrial circuits without compromising response time
• Three-pole design ensures synchronized disconnection of all phases, reducing the risk of phase imbalance and arc-related hazards
• Part number LAB3350V provides clear traceability for procurement, maintenance, and replacement within complex electrical systems

Benefits and practical impact

• Protects valuable equipment from overloads and short circuits, helping minimize unplanned downtime and repair costs
• Enhances personnel safety by ensuring rapid, coordinated breaker action across all phases during faults
• Simple integration into existing high-voltage panels and switchgear designed for three-pole protection
• Supports reliable long-term operation in industrial environments where voltage stability and protection accuracy matter

Practical tips for best results

• Verify that your distribution system and panel are rated for 3350 V and compatible with a 3-pole LAB3350V device
• Coordinate with upstream protection and downstream protection schemes to optimize tripping selectivity and minimize nuisance outages
• Maintain documentation with the exact part number LAB3350V for future maintenance, ordering, and replacement parts
• Schedule periodic inspection and testing by qualified personnel to ensure clean contacts and reliable actuation
