Designed for commercial and industrial power systems, the 90A ED43B090L provides thermal-magnetic trip functions for long-time and instantaneous protection. This unit-mount MCCB features a 65kAIC rating at 240V and 18kAIC at 480V. It installs into individual enclosures, switchboards, and motor control centers, coming factory-equipped with line and load lugs (LN1E100) for immediate wiring. As a legacy SENTRON ED frame component, it can be substituted with the newer 3VA5190-4ED31-0AA0 model.Specifications

Product FAQs
7 answersWhat does the L suffix mean in the ED43B090L catalog number?
The L suffix indicates that the circuit breaker is factory-assembled with both line and load side lugs. The included lugs accept 10 to 1/0 AWG copper or aluminum wire.
Which Siemens enclosures fit the ED43B090L circuit breaker?
This breaker fits Siemens Type ED circuit breaker enclosures. Common compatible enclosures include the NEMA 1 surface-mount E2N1S, the NEMA 1 flush-mount E2N1F, and the NEMA 12 E2N12K, which are designed specifically for ED4, ED6, and HED4 frames.
Can the ED43B090L circuit breaker be reverse fed?
Yes. Siemens ED frame circuit breakers feature a non-interchangeable trip unit and are suitable for reverse feed applications in accordance with UL 489 standards.
How should the ED43B090L be wired for 250VDC systems?
For 250VDC applications, Siemens recommends using two poles of the circuit breaker, with one pole wired on each leg of the direct current supply circuit.
What is the mounting hardware torque specification for this ED frame breaker?
When unit mounting the breaker to a backpan or enclosure, the mounting hardware should be torqued to 12 to 15 in-lbs. Always check the breaker faceplate for the specific lug torque requirements based on your installed wire gauge.
Does the ED43B090L mount directly to a panelboard bus?
No. This is a unit-mount circuit breaker designed to be bolted directly to a backpan, individual enclosure, or switchboard mounting plate. It is not designed for plug-in or bolt-on bus connections in standard lighting panelboards.
What is the modern 3VA series replacement for the ED43B090L?
The legacy SENTRON ED frame has been superseded by the Siemens 3VA series. The direct functional replacement for this 90A, 3-pole, 18kAIC at 480V breaker is catalog number 3VA5190-4ED31-0AA0.
