In the realm of industrial automation and electrical distribution, the HLN series represents a category of high-performance modular devices designed for critical control and protection functions. These components, often referred to as miniature circuit breakers (MCBs) or residual current devices (RCDs) depending on the specific variant, are engineered to handle nominal currents ranging from 6A to 63A with a breaking capacity up to 10kA per IEC 60898-1 standards. They typically feature 1P, 2P, 3P, or 4P configurations, with rated voltages up to 415V AC and 250V DC, making them suitable for both single-phase and three-phase systems. The HLN series is characterized by its compact modular design, allowing for DIN rail mounting in standard distribution boards, and includes thermal-magnetic trip mechanisms for overcurrent and short-circuit protection. Accessories such as auxiliary contacts, shunt trips, and undervoltage releases are available to enhance functionality in complex automation schemes.
These devices are predominantly deployed in industrial control panels, building management systems, and renewable energy installations, including photovoltaic arrays and wind turbine converters. They are also integral to motor control centers (MCCs) and programmable logic controller (PLC) cabinets, where reliable overcurrent protection is paramount. In commercial settings, HLN series components are used in lighting distribution boards, HVAC systems, and elevator control circuits, ensuring compliance with local electrical codes and safety standards. Their robust construction and wide operating temperature range (-25°C to +55°C) make them suitable for harsh environments such as factories, data centers, and outdoor substations.
The HLN category encompasses several subcategories, including the HLN-C series for standard protection, HLN-D for selective coordination, and HLN-S for surge protection. Key article codes follow a structured nomenclature: HLN-1P-C16 (single-pole, 16A, C-curve), HLN-3P-D32 (three-pole, 32A, D-curve), and HLN-4P-S40 (four-pole, 40A, surge protection). These codes are typically composed of the series prefix (HLN), number of poles (1P, 2P, 3P, 4P), trip characteristic (B, C, D, K, S), and rated current in amperes. For example, HLN-2P-B10 indicates a two-pole device with B-curve and 10A rating. The range also includes residual current circuit breakers (RCCBs) coded as HLN-R-30mA-2P and combined RCBOs like HLN-RCBO-16A-30mA-1P+N.
