DPX3 Molded Case Circuit Breakers (MCCBs) represent a cornerstone of modern low-voltage electrical distribution, engineered for high-performance protection and control in industrial and commercial power systems. These devices, often referred to as molded box circuit breakers or compact breakers, are designed to handle significant current ratings, typically ranging from 160A to 1600A, with various pole configurations including 3P and 4P. The DPX3 series offers high breaking capacities (up to 70kA at 415V AC) and adjustable thermal-magnetic or electronic trip units, ensuring precise overload and short-circuit protection. They are suitable for both fixed and withdrawable mounting, with a wide range of accessories such as shunt trips, undervoltage releases, and auxiliary contacts. The robust molded case construction provides high dielectric strength and mechanical endurance, making them ideal for demanding environments.

These MCCBs are primarily deployed in main distribution boards, sub-distribution panels, and motor control centers across sectors like manufacturing, data centers, renewable energy plants, and commercial buildings. They are critical for protecting cables, transformers, and motors against faults, and are often used as incoming or outgoing feeders in switchgear assemblies. Their compact design allows for space-efficient installation in crowded electrical rooms, while the modular accessory system simplifies integration into complex automation networks.

The DPX3 category includes several subcategories based on frame size and breaking capacity, such as the DPX3 160, DPX3 250, DPX3 630, and DPX3 1600. Key article codes follow a structured naming convention, for example, DPX3 160 3P 160A (code: DPX31603P160) or DPX3 630 4P 630A (code: DPX36304P630). These codes typically include the series name, number of poles, and rated current, allowing for quick identification. Other relevant articles include electronic trip units (e.g., DPX3-E-630) and mechanical interlock kits for generator changeover applications.

At Electric Automation Network, we provide genuine DPX3 molded case circuit breakers with real-time pricing and global express shipping. Our team of specialized electrical engineers offers personalized technical support, helping you select the correct frame size, trip unit, and accessories for your specific application. We also provide detailed technical documentation, including wiring diagrams and performance curves, ensuring seamless integration into your power distribution system.
