Product FAQs
7 answersDoes the Siemens 3VA4150-4ED34-0AA0 replace older ED-frame circuit breakers?
Yes, this 3VA41 frame breaker serves as a modern functional replacement for legacy 50A ED4 and ED6 series breakers, such as the ED43B050, in Siemens panelboards.
What does the "LI" trip function code indicate on this Siemens breaker?
The "LI" designation means the thermal-magnetic trip unit provides Long-Time (L) overload protection and Instantaneous (I) short-circuit protection. On this specific 50A model, both the thermal and magnetic trip thresholds are fixed and cannot be field-adjusted.
Is this 50A circuit breaker approved for reverse-feed applications?
Yes, because the TM210 thermal-magnetic trip unit is non-interchangeable, this breaker is UL listed for reverse-feed installations.
Are lugs included on both the line and load sides of this breaker?
Based on its specific catalog number ending in 4-0AA0, this panel-mount breaker is supplied with lugs installed on the load side only. The line side is designed to connect directly to the panelboard bus.
Can the 3VA4150-4ED34-0AA0 be used to protect HVAC equipment?
Yes, this breaker is HACR rated, making it fully certified for safe use with heating, air conditioning, and refrigeration equipment.
Is this breaker rated for switching lighting circuits?
Yes, this model is HID rated, meaning it is certified to safely switch high-intensity discharge lighting loads without nuisance tripping.
What is the maximum frame capacity of the 3VA41 series?
While this specific circuit breaker is equipped with a fixed 50A trip unit, the Siemens 3VA41 frame itself is built to handle a maximum structural capacity of 125A.
