Product Description

The 20F14NB154JA0 is a high-performance NB154 circuit breaker and motor protector engineered for industrial motor control systems. Designed as a 154JA0 motor protector, it integrates overload and short-circuit protection with advanced thermal monitoring. It supports 3-phase input (380-480V AC, 50/60Hz) and delivers 1 output channel, compatible with motors up to 154A. Featuring Modbus RTU communication via RS-485 interface, it enables real-time data exchange with PLCs or SCADA systems. Operating temperature ranges from -25°C to +70°C, ensuring reliability in harsh environments like manufacturing plants or energy infrastructure. Key advantages include precision fault diagnostics, adjustable trip thresholds, and DIN-rail mounting. Limitations include no built-in display or wireless connectivity. Detection response time is <20ms, optimizing equipment safety. Suitable for pumps, compressors, and conveyor systems requiring robust motor protection.
