Description
A dependable solution for industrial facilities, the Siemens EE1B025 is a 1-pole, 25A legacy circuit breaker. It provides fixed thermal magnetic trip functions to protect branch circuits. This E-frame device installs into Siemens Sentron and classic ITE panelboards. It is frequently used to maintain older systems, though the ED21B025 is available as a drop-in replacement. The breaker offers a 10kAIC rating at 120VAC and accepts 14-1/0 AWG wire.Specifications

Product FAQs
7 answersWhich panelboards accept the EE1B025 circuit breaker?
This breaker is compatible with Siemens Sentron panelboards and legacy ITE panelboards designed to accept E-frame bolt-on circuit breakers.
What wire sizes and materials are approved for the EE1B025 lugs?
The standard lugs accept 14 AWG through 1/0 AWG copper or aluminum wire. Always verify the specific torque requirements printed on the breaker label before terminating conductors.
How does the EE1B025 mount into the panelboard?
It utilizes a bolt-on connection. The breaker must be physically bolted to the panelboard bus, which provides a secure, vibration-resistant electrical connection compared to plug-in alternatives.
Can the EE1B025 be used in direct current (DC) applications?
Yes, this breaker carries a DC rating of 125VDC with a 5kA interrupting capacity. It can be safely applied in DC control circuits or for small DC loads within these parameters.
What is the maximum short-circuit interrupting rating for the EE1B025 on AC power?
The breaker is rated for a maximum of 10kAIC at 120VAC. For systems with higher available fault currents, a fully rated or series-rated breaker with a higher interrupting capacity is required.
Can I use the Siemens EE1B025 to replace an older ITE EE1B025?
Yes. Siemens acquired ITE and continues to manufacture this exact E-frame breaker. The Siemens EE1B025 is a direct, interchangeable replacement for the legacy ITE version.
What type of trip mechanism does the EE1B025 use?
It utilizes a non-interchangeable thermal-magnetic trip unit. The fixed long-time and instantaneous (LI) functions provide standard overload and short-circuit protection.
