Siemens control box base AGK11

The Siemens AGK11 is a control box base for a plug-in burner control. It provides an electro-mechanical multi-pin pattern plug-in connection. The base carries terminal connections for field wiring such as supply voltage, flame detector, pressure switches, actuator drives, and the ignition transformer. It has no active logic. This base is designated as type 4.01551.0 or 04015510.

Parts of this type are selected by the exact series and type designation of the burner control they must accept, as well as the required wiring arrangement. Before ordering, verify the plug pattern and pin assignment match the existing base. The base must suit both the control model and the existing field connections. A mismatched base can prevent correct operation or cause wiring errors.

Common failure modes of this kind of base are corrosion and physical damage. A damaged base can interrupt the connection, causing the burner to fail to operate or to compromise safety times. Inspect the base for corrosion, damaged pins, and confirm the plug pattern matches the burner control.
