Description

Part of the QuickSystem line, the Siemens QS2100H provides 100A main service protection with an upgraded 22 kAIC interrupting capacity. It is specifically designed to plug into Siemens Power Mod meter stacks and Uni-PAK metering enclosures. This two-pole breaker replaces legacy MPD2100KH and MDH100 models, offering a seamless upgrade path. The unit features a side-wired configuration that eliminates the need for filler plates while simplifying wire bending in tight compartment spaces.

Product FAQs

5 answers
What metering equipment is the Siemens QS2100H compatible with?

The QS2100H is designed specifically for use as a tenant main breaker in Siemens Power Mod meter stacks and Uni-PAK multi-family metering enclosures.

Will the QS2100H fit in Siemens SP or MP series metering equipment?

No. While the QS2100H is compatible with WP, WPC, WEP, WPL, and Uni-PAK metering lines, it will not fit in SP or MP series enclosures.

Can the QS2100H be installed in a standard Siemens residential load center?

No. The QS frame is engineered for Power Mod and Uni-PAK metering lines. Standard Siemens residential load centers typically require QP, QN, or EQ frame main breakers depending on the panel design.

What is the benefit of the side-wired design on QS frame breakers?

The exclusive side-wired configuration saves valuable wiring space inside the meter stack. It eliminates the need to bend large conductors into difficult S-shapes, which speeds up installation and reduces wire waste.

Does the QS2100H provide GFCI or AFCI protection?

No. This is a standard thermal-magnetic breaker equipped with long-time and instantaneous trip functions for overload and short-circuit protection. It does not provide arc fault or ground fault protection.
