In the realm of industrial electrical distribution and motor control, the E250 series represents a robust line of molded case circuit breakers (MCCBs) designed for high-performance protection. These devices are engineered to handle nominal currents up to 250A, with breaking capacities suitable for both residential and light industrial applications. The E250 breakers typically feature 3-pole (3P) or 4-pole (4P) configurations, supporting operational voltages up to 690V AC and frequencies of 50/60 Hz. They incorporate thermal-magnetic trip units for precise overload and short-circuit protection, with adjustable settings for flexibility. The compact design allows for easy installation in distribution panels, switchboards, and motor control centers, while optional accessories like shunt trips, undervoltage releases, and auxiliary contacts enhance functionality. The E250 series is known for its reliability in protecting cables, motors, and other critical equipment against electrical faults.
The E250 circuit breakers are widely deployed across various sectors, including commercial buildings, industrial plants, and infrastructure projects. They are commonly used in main distribution boards (MDBs), sub-distribution boards (SDBs), and motor control centers (MCCs) for protecting lighting circuits, power outlets, HVAC systems, and machinery. In industrial automation, these breakers safeguard variable frequency drives (VFDs), soft starters, and control panels. Their robust construction makes them suitable for harsh environments, with IP20 or higher protection ratings when installed in appropriate enclosures. The E250 series also finds applications in renewable energy systems, such as solar photovoltaic (PV) arrays and wind turbine installations, where reliable overcurrent protection is critical.
The E250 category encompasses several subcategories and key article codes that define the product range. The main article codes typically follow a structured format: E250-3P-250A, E250-4P-200A, or E250-3P-160A, where the number of poles and nominal current rating are specified. Common subcategories include fixed thermal-magnetic breakers, adjustable magnetic-only breakers, and electronic trip units for advanced protection. Accessories like the E250-AUX auxiliary contact, E250-SHT shunt trip, and E250-UVT undervoltage release are also part of the ecosystem. The E250 series is often complemented by the E125 and E400 series for different current ranges, ensuring a scalable solution for various installation requirements.
