Frequently Asked Questions (FAQ)
-
What is the primary function of the ABB ASFC-01C?
The ASFC-01C monitors and controls fused switch circuits, detecting blown fuses and enabling remote supervision. -
Can it detect partial fuse failures?
Yes, the controller can identify underperformance or degradation trends based on voltage/current differentials. -
Is Modbus the only communication protocol supported?
Currently, RS-485 with Modbus RTU is the default; custom protocols may require firmware upgrades. -
Can it be used in outdoor panels?
The controller itself must be installed in a protected enclosure (e.g., IP54+ panel), as its PCB is rated IP20. -
Does it work with all fuse types?
It is compatible with most industrial fuses, including gG, aM, and class J/T types. -
How does it indicate a blown fuse?
Via both LED indicator and relay output, which can be wired to alarm systems or PLC inputs. -
Is there a built-in power supply?
No, it requires external power (AC or DC depending on installation). -
How often should the controller be calibrated or tested?
ABB recommends testing functionality during regular maintenance intervals, typically annually. -
Can the device trip a breaker upon fuse failure?
Yes, the output relay can trigger contactors, breakers, or alarm systems depending on configuration. -
What are the installation best practices?
Ensure clean power supply, proper grounding, and secure DIN/panel mounting with minimized cable interference.
