Selection Notes
The '4' in OXB800E3S4QB marks the Level 4 touchscreen controller, the highest monitoring tier available on the 4-pole, switched-neutral 800 A frame. Step up to this controller from the Level 2 or Level 3 units in the same S-series when the site needs touchscreen configuration and a fuller transfer-event log rather than DIP switches or a basic LCD readout.
