The integrated ETU560 trip unit features an LCD display and adjustable LSIG functions. It delivers a Class H breaking capacity of 65kA at 480V.
Which panelboards are compatible with the 3VA6225-6JQ31-0AA0 circuit breaker?
This 250A breaker mounts into Siemens P1, P2, P3, P4, and P5 panelboards, as well as compatible switchboards and motor control centers.
Can I use this breaker to replace an older Siemens HFD63B250?
Yes. With the appropriate retrofit kit, this 3VA6 breaker serves as a drop-in replacement for discontinued HFD63B250 circuit breakers.
What does the LSIG designation mean on this breaker's trip unit?
LSIG indicates that the electronic trip unit provides adjustable protection for Long-time overload, Short-time short circuit, Instantaneous short circuit, and Ground-fault conditions. This allows for precise system coordination.
What does the Class H rating mean for this 250A breaker?
The Class H designation indicates a high breaking capacity, providing 65kA of short-circuit interrupting capability at 480V AC for demanding industrial environments.
What is the adjustable amperage range for this 250A breaker?
The integrated ETU560 electronic trip unit allows the continuous current overload protection (Ir) to be adjusted from 100A up to the maximum 250A frame rating.
Does this breaker include an LCD screen for configuration?
Yes, the ETU560 electronic trip unit features an integrated LCD display to simplify the setup and adjustment of your protection parameters.
How does the ground-fault protection (G) enhance system safety?
The ground-fault function detects low-level leakage currents to ground. This helps prevent equipment damage and reduces the risk of electrical fires before a major short circuit occurs.
What is the difference between Siemens 3VA5 and 3VA6 breakers?
The 3VA5 series uses standard thermal-magnetic trip units, while the 3VA6 series utilizes advanced electronic trip units (ETU) for more precise coordination, metering, and communication capabilities.
