Moulded Case Circuit Breakers (MCCBs) from the 3VL SENTRON series are high-performance protective devices designed for industrial and commercial power distribution systems. These circuit breakers are available in 3-pole (3P) and 4-pole (4P) configurations, with rated currents ranging from 160 A to 630 A, and breaking capacities up to 50 kA at 41...
Moulded Case Circuit Breakers (MCCBs) from the 3VL SENTRON series are high-performance protective devices designed for industrial and commercial power distribution systems. These circuit breakers are available in 3-pole (3P) and 4-pole (4P) configurations, with rated currents ranging from 160 A to 630 A, and breaking capacities up to 50 kA at 415 V AC. They feature electronic or thermal-magnetic trip units for precise overload and short-circuit protection, adjustable settings for current and time delays, and a compact design suitable for fixed or plug-in mounting. The 3VL series supports a wide range of accessories, including auxiliary contacts, shunt trips, undervoltage releases, and motor operators, enabling seamless integration into automation systems. With a rated insulation voltage of 690 V and compliance with IEC 60947-2, these MCCBs ensure reliable operation in demanding environments.
These MCCBs are primarily used in main distribution boards, sub-distribution panels, and motor control centers within industrial plants, commercial buildings, and infrastructure projects. They are ideal for protecting feeders, transformers, capacitors, and large motors in sectors such as manufacturing, energy, water treatment, and data centers. The 3VL series is also suitable for generator protection and backup power systems, where high breaking capacity and selectivity are critical. Their modular design allows for easy installation in switchgear cabinets, and the optional communication modules enable remote monitoring via fieldbus systems like PROFIBUS or Modbus.
The 3VL SENTRON series includes several subcategories based on frame size and breaking capacity. Key article codes include 3VL160 (160 A frame), 3VL250 (250 A frame), 3VL400 (400 A frame), and 3VL630 (630 A frame). The code structure typically follows the pattern 3VLXXXX-XXXXX, where the first digits indicate the frame size and rated current, and the suffix defines the trip unit type, number of poles, and accessories. For example, 3VL160-1DC33-0AA0 represents a 160 A, 3P, thermal-magnetic MCCB. Other variants include 3VL250-1DC33-0AA0 and 3VL400-1DC33-0AA0, each offering different breaking capacities and trip characteristics.
