FAQs

Q1: What is the primary function of this circuit breaker?
The 3VA2580-6HL32-0AA0 provides overload and short-circuit protection for electrical distribution systems, protecting cables, motors, and other equipment from damage due to abnormal current conditions .
Q2: What is the difference between ETU320 and ETU860?
The ETU320 is the basic tier electronic trip unit providing LI protection (Long-time overload + Instantaneous short-circuit) . The ETU860 is a higher-tier unit that adds LSI or LSIG protection (Short-time delayed short-circuit, Ground fault) plus metering and communication capabilities . The ETU320 is protection-only with no display beyond basic trip indication .
Q3: What does "LI" mean in the trip unit designation?
LI denotes two protection functions:
-
L (Long-time): Adjustable overload protection (Ir = 320–800 A) with inverse-time delay characteristics
-
I (Instantaneous): Adjustable short-circuit protection (Ii = 1.5–10 × In) that trips without intentional delay
Q4: What is the breaking capacity of this breaker?
The 3VA2580-6HL32-0AA0 has a breaking capacity class H rating:
-
85 kA @ 415 V (Icu)
-
110 kA @ 240 V
-
55 kA @ 500 V
-
35 kA @ 690 V
This makes it suitable for high-fault-current industrial installations.
Q5: Can this breaker be upgraded with communication modules?
No, not directly on this model. The ETU320 trip unit is protection-only and does not support communication functions . For Modbus, PROFIBUS, or PROFINET communication, you would need a model with ETU650 or ETU860 trip units, or use external communication modules where applicable.
