Description
Built to protect circuits against overloads and short circuits, the Siemens E22B050 molded case circuit breaker is rated 50A and 240VAC, with 2 poles and a 10kA interrupting rating at 240VAC. The single-phase E2 series breaker uses an E-Frame with bolt-on mounting. Its fixed thermal and fixed magnetic trip provides long-time and instantaneous protection. It has a load side lug terminal connection and operates at 40 °C.Specifications

Product FAQs
6 answersWhat electrical ratings should I use to select the Siemens E22B050?
The Siemens E22B050 is rated 50A at 240VAC. Use the current rating to coordinate circuit loading and conductor protection, and the voltage rating to select it for the circuit's AC operating voltage.
When should I choose a 2-pole breaker for a single-phase circuit?
The E22B050 has two poles for a single-phase application. Choose this pole configuration when the circuit requires switching two conductors rather than one.
How do I evaluate the 10kA interrupting rating?
The E22B050 has a 10kA interrupting rating at 240VAC. The available fault current at the installation point must not exceed that rating, so compare the circuit's available fault current with this limit before selecting the breaker.
Can I adjust the overload or instantaneous trip settings?
No. The thermal and magnetic trip settings are fixed. The thermal element responds to sustained overloads, while the magnetic element responds to high fault currents, so select the breaker around its fixed protection characteristics rather than planned field adjustments.
How is the E22B050 mounted?
The E22B050 uses bolt-on mounting rather than a plug-in attachment. Plan installation for a bolted connection and secure the mounting connections properly.
How are the outgoing circuit conductors connected?
The E22B050 uses load-side lug connections for outgoing circuit conductors. Terminate the load conductors at these lugs and secure the connections properly to maintain a reliable electrical connection.
