Product FAQs
6 answersCan the Siemens ED43B020 be used to replace a legacy ITE circuit breaker?
Yes. Siemens acquired the ITE brand and continues to manufacture these ED frame models. This unit serves as an exact, direct replacement for older ITE ED43B020 breakers without requiring any panelboard modifications.
Are line side lugs included with this circuit breaker?
No. Like most ED frame breakers, this unit includes standard load side lugs only. If your specific application requires line side lugs, you must install an add-on lug kit. The correct line side lug kit for 15 to 25 amp models is Siemens part number SA1E025.
Is the ED43B020 circuit breaker approved for reverse feeding?
Yes. This Sentron series thermal magnetic circuit breaker does not have line and load side restrictions, meaning it is fully approved to be reverse connected in your electrical system.
Is this circuit breaker rated for use with HVAC equipment?
Yes. This unit carries an HACR rating, which means it has been tested and approved for safe use with heating, air conditioning, and refrigeration systems.
What is the modern 3VA series replacement for this Sentron ED4 circuit breaker?
For new installations or system upgrades, Siemens offers the 3VA series as the modern equivalent. The direct crossover model for this 20 amp breaker is part number 3VA5120-4ED31-0AA0.
Can I use compression lugs with this circuit breaker?
Yes. While standard mechanical lugs are included on the load side, you can equip all ED frame breakers with compression type lugs. You will need to use Siemens catalog number CCE125 for compression lug compatibility.
