Description
Built for industrial environments, the Siemens 3VA4145-6ED34-0AA0 is a 3-pole, 45A molded case circuit breaker. It utilizes a TM210 thermal-magnetic trip unit to deliver precise long-time and instantaneous (LI) protection. This panel mount breaker installs into Siemens P1 through P5 panelboards and switchboards. It is an ideal modern substitute for the legacy ED63B045 breaker. Featuring a 65kAIC rating at 480V, this Class H device is current limiting and reverse feed capable.Specifications

Product FAQs
7 answersCan the 3VA4145-6ED34-0AA0 replace older Siemens ED frame circuit breakers?
Yes, the 3VA4 series is the modern replacement for legacy Siemens ED frame breakers, including ED4, ED6, and HED4 models. It is designed to mount into the same Siemens P1 through P5 panelboards and switchboards.
Does this breaker require a specific filler plate when installed in a Siemens P1 panelboard?
When replacing an older breaker or installing this 3VA4 breaker in a Siemens P1 panelboard, you may need a compatible filler plate kit designed for 3VA4, BL, BQD, or ED frames to properly cover any panel gaps.
What type of protection does the LI trip function provide on this 3VA41 breaker?
The LI designation indicates it features a thermal-magnetic trip unit with Long-Time (L) and Instantaneous (I) protection. The fixed thermal element protects against overloads, while the fixed magnetic element protects against short circuits.
Can the 3VA4145-6ED34-0AA0 be reverse fed?
Yes, all Siemens 3VA41 thermal-magnetic trip circuit breakers are UL listed for reverse feed applications, providing flexibility for various installation requirements.
Is this 3VA4 breaker suitable for direct current (DC) systems?
Yes, this breaker is rated for up to 250VDC with a 100kA interrupting capacity, making it suitable for both AC and DC power distribution applications.
What does the current-limiting design of the 3VA4145-6ED34-0AA0 achieve?
The current-limiting design reduces the amount of fault energy let-through during a short circuit, which helps minimize potential thermal and mechanical damage to downstream equipment.
Is the 3VA4145-6ED34-0AA0 suitable for HVAC applications?
Yes, this breaker is HACR rated, meaning it is approved for use with heating, air conditioning, and refrigeration equipment.
