Description
Built for motor applications, the Siemens ET5916 is a 3-pole, 200A magnetic-only circuit breaker. It delivers reliable short-circuit protection for industrial motor control centers at up to 600VAC. As a legacy LMD frame component, this unit provides an exact replacement fit for older Siemens and ITE systems. Facilities upgrading panels can substitute it with the modern JXD63B200 breaker. It features an adjustable magnetic trip setting ranging from 1000A to 2000A for precise load calibration.Specifications

Product FAQs
8 answersWhat is the magnetic trip adjustment range for the ET5916?
The ET5916 features an adjustable magnetic trip setting that ranges from 1000A to 2000A, allowing for precise load calibration in motor applications.
Does the ET5916 provide thermal overload protection?
No. The ET5916 is an instantaneous-only (magnetic-only) motor circuit protector. It provides short-circuit protection but requires a separate overload relay or starter for thermal motor protection.
What types of systems is the Siemens ET5916 designed to protect?
This magnetic-only breaker is specifically designed to provide short-circuit protection for industrial motor control centers.
Is there a modern replacement for the legacy ET5916 circuit breaker?
Yes. Facilities upgrading their panels can substitute the legacy ET5916 with the modern Siemens JXD63B200 circuit breaker.
What wire sizes are compatible with the lugs on this breaker?
The included line and load lugs accept copper (Cu) or aluminum (Al) wire ranging from 3/0 AWG to 350 kcmil.
How is the ET5916 circuit breaker installed?
The ET5916 features a unit-mount design. It is individually mounted to a backpan or enclosure and wired using the provided line and load lugs, rather than connecting directly to a panelboard bus.
Why is it important to calibrate the adjustable magnetic trip on the ET5916?
Calibrating the magnetic trip setting ensures the breaker responds instantly to short-circuit faults specific to your motor's inrush current, preventing nuisance tripping while maintaining optimal safety.
Can the ET5916 be used in DC electrical systems?
Yes, this breaker is rated for use in DC applications up to 250VDC, with a maximum interrupting capacity of 10kA at that voltage.
