SIEMENS Q Duplex Circuit Breaker 20/20A 120/240VAC

SKU CH-JM8T-862CA

A duplex plug-in breaker delivers two 20 A circuits in one slot for Siemens EQ load centres at 120/240 VAC with a 10 kA interrupting rating

  • Duplex design fits two 20 A circuits in one slot
  • Plug-in mounting installs quickly in Siemens EQ load centers
  • 10 kA interrupting rating handles short-circuit faults safely
  • Toggle actuator gives clear on/off indication
  • Accepts 14 to 8 AWG wire for flexible wiring

Dual-Circuit Protection

The SIEMENS Q duplex breaker fits a single EQ load-center slot and supplies two independent 20 A circuits at 120/240 VAC. Each pole carries a 10 kA interrupting rating at 120 VAC. Plug-in mounting and lug terminals accept wire from 14 AWG up to 8 AWG.

Homeowners Adding Circuits

This breaker suits owners of compatible Siemens EQ panels who need two new 120 V branch circuits without adding a sub-panel. It will not serve installations that require a 240 V common-trip breaker, panels outside the EQ series, or loads exceeding 20 A per pole.

Panel Integration

The plug-in design installs directly onto the EQ bus, freeing the adjacent slot that a standard two-pole breaker would occupy. Lug terminals simplify wire landing for 14–8 AWG conductors, and the 125 A frame rating matches the panel’s bus capacity.

Questions about this item

What load center series must I already have installed to accept this SIEMENS Q duplex breaker?

It is designed for Siemens EQ load centers, so the panel must be from that series.

Will this duplex breaker fit in a panel that currently uses single-pole QP breakers?

Yes, the plug-in mounting style matches the QP frame size, allowing it to occupy one slot while providing two 20 A circuits.

After installation, how can I verify the breaker is operating correctly?

Switch each toggle to ON and confirm the connected 120 V circuits carry load; the breaker will trip at 20 A per pole if an overcurrent occurs.
