Product FAQs
8 answersHow should I use the 70A rating when selecting the Siemens ED41B070?
The Siemens ED41B070 has a rated current of 70A. Use that rating when coordinating the breaker with the circuit load and conductor ampacity under applicable electrical requirements.
Can I use the ED41B070 on AC or DC circuits?
The ED41B070 is rated for 120VAC, 277VAC and 125VDC. Match both the circuit voltage and the AC or DC supply type when selecting it.
How does the 22kAIC rating affect selection for a 277VAC circuit?
The interrupting rating is 22kAIC at 277VAC. For a 277VAC installation, the available fault current must not exceed this rating so the breaker can safely interrupt a fault.
How does the ED41B070 respond to overloads and short circuits?
Its thermal-magnetic trip uses long-time thermal operation for sustained overloads and instantaneous magnetic operation for short circuits. Both trip elements are fixed, so select it for applications that do not require adjustable trip settings.
When should I select the single-pole ED41B070?
The ED41B070 is a single-pole breaker for single-phase applications. Select it when the circuit design requires one protected pole.
What mounting method should I plan for with the ED41B070?
The ED41B070 uses bolt-on mounting. Plan for a bolted mounting connection during installation rather than a plug-in connection.
What conductor sizes can I terminate at the load-side lug?
The load-side lug accepts conductors from 6 AWG through 1/0 AWG. Choose a conductor within that range while also meeting the circuit's ampacity requirements.
How much physical space should I account for when planning the installation?
The breaker measures 6.35 in high, 1 in wide and 3.92 in deep. Use these dimensions to plan installation space and conductor routing.
