RFB junction boxes provide ABS housings for electrical connections, communication equipment and control assemblies. The range includes round and rectangular boxes with cable-entry provisions. Internal base holes support circuit board or DIN rail installation, while external fixing holes allow mounting to walls or flat panels.
Open the required knockout and install a suitable cable gland to maintain the specified cable-entry seal. RT and RA constructions use different entry arrangements; select the required model and entry style from the drawings. The ABS material offers electrical insulation and resistance to impact, heat, low temperatures and chemicals within the chosen application conditions.
A separate surface-mount cover configuration uses a foam seal and screw fixings. Specify the required cover style and cable-entry arrangement with the enclosure.
The first two round models use diameter × depth dimensions. Other model dimensions are length × width × depth in millimeters. The listed weights apply to the packed carton quantity, not to a single box.
