Engineering Advantages
- High Sensitivity Detection: Accurately identifies residual currents to prevent latent ground faults from escalating into equipment failures or fires.
- Fast Trip Response: Minimizes exposure time to fault conditions, protecting both personnel and downstream equipment.
- Relay Contact Output: Directly interfaces with PLCs, SCADA systems, and alarm circuits without additional signal conditioning.
- Compact Form Factor: Optimized for space-constrained control panels with DIN rail compatibility.
- HONEYWELL OEM Quality: Manufactured to HONEYWELL’s industrial reliability standards, ensuring long service life in demanding environments.
System Architecture & Signal Flow
The 10310/2/1 monitors the vector sum of phase and neutral currents via a toroidal current transformer (CT). Under normal conditions, the sum equals zero. When a ground fault occurs, the imbalance exceeds the set threshold, triggering the internal relay. The relay contact output then signals the upstream circuit breaker, PLC input, or alarm system to initiate a protective response. This architecture ensures fail-safe operation independent of the main control logic.
