Product Description

The NA1-5 series combines advanced protection technologies, integrating the NA1-5 Circuit Breaker, NA1-5 Thermal Relay, and NA1-5 Motor Protector into a robust industrial solution. Designed with 3-phase input and 2 output channels, it directly interfaces with contactors, sensors, and control modules. Supporting Modbus RTU communication, it operates within 220-480V AC and a temperature range of -20°C to 60°C. Ideal for manufacturing, energy, and heavy industries, it provides precise overload, short-circuit, and motor phase-loss protection. Key advantages include high fault tolerance and modular installation, though its larger footprint may require additional panel space. The NA1-5 Motor Protector features a 20mm diagnostic LED indicator and responds to thermal anomalies within a 0.5m sensing range, ensuring rapid system shutdown for critical machinery safety.
