Siemens SHMD69800ANTH Molded Case Circuit Breaker

Siemens has transitioned the Sentron MD-frame series to the newer 3VA series. The direct functional equivalent is the 3VA6580-6HN32-2AA0. However, upgrading to the 3VA series requires a retrofit kit and panel modifications. Using the exact SHMD69800ANTH replacement allows you to avoid these modifications.

The "S" indicates that the breaker uses a Sensitrip solid-state electronic trip unit rather than a standard thermal-magnetic trip. The "H" designates it as a High Interrupting capacity breaker, rated for 65kAIC at 480V and 50kAIC at 600V.

Yes, the "N" in the catalog number suffix indicates that this breaker is 100% rated. This allows the breaker to carry its full 800A continuous current rating in an appropriately sized and ventilated enclosure, rather than being limited to the standard 80% continuous load rating.

This MD-frame breaker requires lugs for wire termination. For standard mechanical connections, use the TA3K500 aluminum lug kit, which accepts three 1/0 AWG to 500 kcmil copper or aluminum conductors per phase. If your application requires compression connections, the CCM800K3 compression lug kit is also compatible.

Yes. Because Siemens acquired I-T-E and maintained the Sentron frame dimensions, this MD-frame breaker is backward compatible with legacy I-T-E panelboards, switchboards, and motor control centers designed for MD-frame breakers.

The Sensitrip electronic trip unit features rotary dials on the face of the breaker. These dials allow you to independently adjust the Long-Time (continuous current and delay), Short-Time (pickup and delay), and Instantaneous (pickup) protection settings to coordinate with your specific system requirements.
