Product Description

The NA2-N28 Relay, also referred to as the NA2-N28 Thermal Relay or NA2-N28 Overload Protector, is a robust industrial protection device engineered for motor control, HVAC systems, and heavy machinery applications. It integrates two input channels and three output contacts (1 NO + 2 NC), supporting direct connections to up to four external control modules. Equipped with Modbus RTU and RS-485 communication interfaces, it operates within a wide voltage range of 220-440V AC and a temperature range of -20°C to +60°C, ensuring adaptability in harsh environments. The device offers precise overload protection with adjustable current thresholds (5-100A) and thermal response time settings, safeguarding against phase loss, current imbalances, and overheating. Its compact DIN-rail-mountable design and IP20-rated enclosure enhance durability, while modular expansion simplifies system integration. Key advantages include high accuracy, customizable trip settings, and compatibility with industrial automation networks, though it lacks built-in display capabilities and requires external monitoring tools for diagnostics.
