Description
The Siemens ET5911 is a 3-pole, 200A molded case circuit breaker designed for robust industrial power distribution. Featuring a thermal-magnetic trip unit, it provides dependable long-time and instantaneous protection for 600VAC systems. This legacy unit mount breaker is engineered to fit into older ITE and Siemens J-Frame panelboards. Officially replaced by the JXD63B200, it delivers a 25kAIC rating at 240V and accepts 3/0 AWG to 350 kcmil wire for secure connections.Specifications

Product FAQs
5 answersIs there a modern equivalent for the legacy ET5911?
Yes, the Siemens JXD63B200 is the direct replacement for the ET5911. Upgrading to the JXD63B200 maintains the 200A rating and fits the same panelboard spaces.
What equipment is the ET5911 designed to fit?
This unit mount breaker is engineered specifically for use in older ITE and Siemens J-Frame panelboards, making it an exact replacement that eliminates the need for custom panel modifications.
How is the trip unit configured on the ET5911?
It utilizes a thermal-magnetic trip unit with a fixed thermal element for long-time overload protection and an adjustable magnetic element for instantaneous short-circuit response.
What are the conductor requirements for wiring the ET5911?
The breaker terminals accept either copper or aluminum conductors ranging from 3/0 AWG to 350 kcmil. Ensure proper torque specifications are followed during installation to maintain a secure connection.
Is the ET5911 suitable for direct current systems?
Yes, in addition to its standard AC ratings, this breaker is rated for 250VDC applications with a 10kA interrupting capacity. This makes it suitable for industrial DC control circuits and battery systems.
