Product FAQs
6 answersWhich panelboards accept the Siemens EE1B030 circuit breaker?
This E-frame breaker is designed for legacy ITE panelboards and Siemens Sentron panelboards. It requires a bolt-on mounting configuration.
What is the modern replacement for the legacy EE1B030 breaker?
The EE frame series has been superseded by the ED frame. For a modern 30A, 1-pole replacement, the Siemens ED21B030 is the direct equivalent.
What wire sizes are compatible with the load lugs on the EE1B030?
The factory-installed lugs accept 14 AWG through 1/0 AWG copper or aluminum conductors.
Is the EE1B030 rated for direct current (DC) systems?
Yes, this breaker carries a DC rating of 125VDC with a 5kA interrupting capacity, making it suitable for specific control circuits and DC applications.
Are the trip settings adjustable on the EE1B030?
No, this breaker utilizes a fixed thermal-magnetic trip unit. Both the long-time overload and instantaneous short-circuit functions are factory set and cannot be adjusted in the field.
What is the advantage of the bolt-on connection used by the EE1B030?
Bolt-on breakers provide a secure, mechanically fastened connection to the panelboard bus. This prevents the breaker from vibrating loose in high-vibration industrial environments and ensures consistent contact resistance.
