Product FAQs
6 answersWhich panelboards are compatible with the Siemens EE2B050?
The EE2B050 is designed for installation in classic ITE panelboards and Siemens Sentron panelboards. It requires a bolt-on connection to the panel bus.
Has the Siemens EE2B050 been replaced by a newer model?
Yes, the legacy EE2B050 E-Frame breaker has been superseded by the Siemens ED22B050. The ED22B050 is the recommended direct replacement for maintaining existing Sentron and ITE panelboard infrastructure.
What wire sizes and materials are accepted by the EE2B050 terminals?
The included load side lugs are rated for both copper and aluminum conductors, accepting wire gauges from 14 AWG up to 1/0 AWG.
What type of protection does the thermal-magnetic trip unit provide on the EE2B050?
The fixed thermal-magnetic trip unit provides standard LI (Long-Time and Instantaneous) protection. The thermal component protects against sustained overloads, while the magnetic component trips instantaneously during short circuits.
How is the Siemens EE2B050 installed into a panelboard?
This breaker utilizes a bolt-on connection. It must be mechanically fastened directly to the panelboard bus bars, which provides a highly secure connection suitable for commercial and industrial environments.
Is it safe to install the EE2B050 in a system with an available fault current above 10kA?
No. The EE2B050 has a maximum interrupting rating of 10kAIC at 240VAC. Installing it in a system with a higher available fault current violates safety standards and can result in catastrophic breaker failure during a short circuit.
