Siemens 3G-CBM-05786 — Technical Specifications

The Siemens Cell QRB1B-D042B20B is a photoresistor-based burner control for oil burner flame monitoring in small power burners, supplied with two-wire thermoplastic cable and bracket mounting (21 mm or 36 mm hole spacing options). Designed for OEM integration with LAL..., LOA..., and LMO... safety control units, it detects visible spectrum yellow oil flame and measures probe current in microamperes, with selectable normal or elevated response sensitivity. The unit complies with ISO 9001:2000, ISO 14001:1996, and 89/336/CEE (EMC Directive), and requires qualified personnel for installation, commissioning, and maintenance; cable must route separately from ignition cables and cleaning is by cloth only. 3G Electric sources and stocks this product for delivery across Singapore and Southeast Asia.
