Brahma Control box 18001352

The Brahma Control box 18001352 is a control unit for forced-draft gas burners, designed for boilers up to 120 kW. It operates at a supply voltage of 220 V and features a safety time of 3 seconds and a pre-purge time of 50 seconds. The unit supports a burner motor current of 4 A, an alarm current of 1 A, and an ignition transformer current of 2000 mA. It has a sensor voltage of 300 V, a protection class of IP40, and a net weight of 0.55 kg. The body is made of plastic, and internal wiring uses flexible unipolar conductors, with the flame detection circuit mounted on a printed circuit board. This control box fits the Brahma SR3/V model.

Control boxes of this type are selected by matching the supply voltage, safety time, and pre-purge time to the burner's specifications. The physical dimensions and mounting configuration must align with the burner's housing, and the electrical connections for the motor, alarm, and ignition transformer must be compatible. Before ordering, verify the boiler capacity and ensure the control box's ratings meet or exceed the burner's requirements.

When control boxes of this kind fail, common symptoms include the burner not starting, intermittent operation, or failure to ignite. The equipment may lock out, indicated by an alarm signal, or the flame detection circuit may not respond correctly. Check the supply voltage, wiring connections, and the condition of the flame sensor for faults.
