Product Description

The NA1-PK5 circuit breaker integrates the functionalities of a thermal relay and motor protector, designed for industrial motor protection systems. It features 3-phase input and 2 relay outputs, directly interfacing with up to 4 auxiliary modules. Supporting Modbus RTU and CANopen communication, it operates within 24-415V AC/DC voltage range and -25°C to +60°C environments. Ideal for manufacturing, energy, and HVAC industries, its precision overload detection (0.5-30A adjustable) and short-circuit protection ensure motor safety. The compact design includes a 2.4-inch status display and 20m sensor range. While offering IP54-rated durability and DIN rail mounting, its configuration requires specialized software expertise. No battery integration; relies on external power.
