Product overview A 4pole circuit breaker panel rated for AC 440V with a 40 kA interrupting capacity. Designed to organize, protect, and distribute threephase electrical power with a dedicated neutral pole. Key benefits fault interruption capacity: 40 kA rating limits damage from short circuits and helps protect downstream equipment and wiring. Full 4pole protection: four poles provide simultaneous switching and protection for all three phases plus neutral, ideal for balanced threephase systems. Clear system compatibility: rated for AC 440V service, making it suitable for common industrial and commercial threephase installations. Spaceefficient layout: 4P configuration saves panel space while delivering complete distribution and isolation for a single circuit location. Simplifies maintenance: centralizes circuit protection for easier inspection and faster fault isolation, reducing system downtime. Primary functions Distribute threephase power with neutral protection. Interrupt fault currents up to 40 kA at AC 440V. Isolate and protect circuits from overloads and short circuits within the rated limits. Performance and compatibility Pole count: 4P, suitable for 3phase plus neutral applications. Voltage rating: AC 440V. Interrupting capacity: 40 kA. Compatible with standard 4pole breaker installations in industrial and commercial panel boards designed for AC 440V systems. Practical considerations Use the panel in systems that operate at or below the rated voltage and within the specified interrupting capability. Mount and wire according to local electrical codes and standard installation practices. Match upstream and downstream components to the panel rating to maintain overall system integrity. Typical applications Industrial distribution: Main or subdistribution panels on manufacturing floors supplying motors, drives, and production equipment. Commercial buildings: Subpanels for HVAC systems, elevators, and centralized electrical closets requiring threephase and neutral protection. Motor control centers: Protection for motor feeders and control circuits where simultaneous phase and neutral switching is required. What makes this panel practical Provides a consolidated solution for threephase plus neutral protection in a single module. interrupting capacity supports installations where shortcircuit currents can be significant. Straightforward integration into existing 4P AC 440V panel assemblies. Ordering and selection tips Verify system voltage and maximum prospective fault current to confirm 40 kA is adequate for your installation. Confirm panel dimensions and breaker mounting compatibility with the intended enclosure or distribution board. Consult a qualified electrician or system designer to ensure the panel meets installation requirements and performs as needed in the specific application.
