FAQ
FAQ
Q1: What is the ABB REF545KB133AAAA?
A: It is an ABB REF 545 feeder protection and control terminal designed for medium-voltage distribution feeders and industrial switchgear.
Q2: What type of current inputs does this REF545 version have?
A: The 133 hardware configuration provides four 1/5 A CT inputs plus one 0.2/1 A CT input.
Q3: How many voltage inputs are available?
A: It provides four voltage-transformer inputs rated for 100/110/115/120 V applications.
Q4: How many digital inputs and outputs does it have?
A: The REF545 platform version has 34 digital inputs. The output arrangement includes three single-pole power outputs, eleven double-pole power outputs, four NO signal outputs and eight NO/NC signal outputs.
Q5: What auxiliary power supply does the REF545KB133AAAA use?
A: The 133 configuration is available with an 80–265 V AC/DC auxiliary supply.
Q6: What functions does the REF545 provide?
A: It integrates feeder protection, breaker control, electrical measurement, event recording, data recording, condition monitoring, power-quality functions and self-supervision.
Q7: What are the dimensions and weight of the REF545?
A: The standard enclosure is approximately 223.7 mm wide × 265.9 mm high × 235 mm deep, and the unit weighs approximately 8 kg.
Q8: Is REF545KB133AAAA the same as every REF545?
A: No. REF545 units were produced in several hardware configurations. The suffix K133AAAA identifies a particular combination of CT/VT inputs, power supply, I/O and mechanical configuration, so the complete ordering code should be checked before replacement.
