Product Description

The NA1-PK3 relay, part of the NA series motor protector range, integrates protection and control functions for industrial applications such as manufacturing, energy, and HVAC systems. It operates within 24-240V AC/DC and supports temperatures from -20°C to +60°C. Equipped with 2 digital inputs and 3 relay outputs, it directly interfaces with up to 4 expansion modules for scalability. Communication via Modbus RTU or RS-485 ensures seamless integration into automation networks. The NA1PK3 circuit breaker functionality provides precise motor protection against overload, short-circuit, phase loss, and imbalance, with adjustable trip thresholds (0.5-50A). Compact and DIN-rail mounted, its key advantages include real-time monitoring, high sensitivity, and modular design, though configuration requires specialized software. Detection ranges cover 10-5000ms response times for fault isolation. The device lacks a display but supports LED indicators for status alerts. Battery-free operation ensures reliability in harsh environments.
