ABB|1JNL100100-591| Low-Voltage Circuit Breaker Trip Unit
ABB 1JNL100100-591 Low-Voltage Circuit Breaker Trip Unit
Description
ABB 1JNL100100-591 is a microprocessor-based electronic trip unit designed for use with ABB’s Emax 2 low-voltage air circuit breakers, providing precise protection and monitoring functions.
Features
Integrated protection against overload, short-circuit, and ground-fault conditions. Supports communication via Modbus RTU protocol. Compact design compatible with Emax 2 frame sizes.
Technical Specifications
Rated operational voltage: 24 V DC (±20%)
Power consumption: ≤3 W
Operating temperature range: –25°C to +70°C
Storage temperature range: –40°C to +85°C
Relative humidity: 5% to 95% non-condensing
Protection functions:
- Long-time delay (L): adjustable from 0.4 to 1.0 × In
- Short-time delay (S): 0.1 s to 0.4 s, pickup 1.5 to 10 × In
- Instantaneous (I): 1.5 to 15 × In
- Ground-fault (G): 0.2 to 1.0 × In, time delay 0.1 to 0.4 s
Accuracy of current measurement: ±2%
