Built for heavy-duty distribution, the Siemens ED42B035 is a 2-pole, 35A molded case circuit breaker. It mounts into Siemens P1, P2, and P3 panelboards to serve commercial and industrial facilities. Belonging to the SENTRON ED4 frame series, it utilizes a non-interchangeable thermal-magnetic trip unit for precise long-time and instantaneous protection. The breaker is HACR and HID rated, reverse feed capable, and provides an 18 kAIC interrupting capacity at 480VAC.
What panelboards are compatible with the Siemens ED42B035?
The ED42B035 is designed to mount into Siemens P1, P2, and P3 panelboards. It is a bolt-on molded case circuit breaker, meaning it requires a bolted connection directly to the panel bus.
What wire sizes do the lugs on the ED42B035 accept?
The factory-installed lugs on this breaker accept 10 AWG to 1/0 AWG copper or aluminum wire.
Is the ED42B035 suitable for reverse feeding?
Yes, this breaker features a non-interchangeable trip unit and is reverse feed capable for applications that require power to flow from the load side to the line side.
Can this breaker be used in direct current (DC) applications?
Yes, the ED42B035 is rated for up to 250VDC with a 30kA interrupting capacity. When applying a 2-pole breaker on a 250VDC system, one pole is typically connected to each leg of the supply circuit.
Is the ED42B035 rated for heating, air conditioning, and refrigeration equipment?
Yes, this breaker is HACR rated, making it suitable for protecting heating, air conditioning, and refrigeration motor circuits. It is also HID rated for high-intensity discharge lighting loads.
Does this breaker replace older ITE versions?
Yes, the Siemens ED42B035 is a direct replacement for the legacy ITE ED42B035. Siemens acquired the ITE product line, and the current Sentron ED frame breakers maintain the same physical dimensions and mounting requirements.
How does the trip unit function on this breaker?
The ED42B035 uses a fixed thermal-magnetic trip unit. It provides long-time protection for overloads and instantaneous protection for short circuits. The trip settings are factory fixed and not adjustable.
Can I install this ED frame breaker in a residential load center?
No, the ED42B035 is a bolt-on molded case circuit breaker designed for commercial and industrial P-Series panelboards. It will not fit in standard residential plug-on load centers that require QP or QT type breakers.
