The Hammond BC2G is a Class 2 energy limiting transformer from the BA-C-D-E small box mount series, rated 12 VA with a 120 V primary and a 24 V, 0.5 A secondary. It is used by electricians, HVAC and security installers and OEMs in chimes, door bells, security systems, decorative lighting, furnaces, humidifiers, appliances, vending machines and intercom type applications.
The BC2G provides a 24 V, 0.5 A secondary from 120 V at 12 VA.
The design is rugged, low noise and cool running, for indoor use only. It is 60 Hz and inherently limited, so no fuses or circuit breakers are required. Input (primary) connections are stripped wire leads, and the output (secondary) is a screw terminal / quick fit tab terminal. Input leads are black.
Installation is by nipple locknut mount into a box, and the transformer comes complete with locknut and mounting bracket. Overall dimensions are A 2.33 in (59 mm), B 2.22 in (56 mm) and C 1.98 in (50 mm), and the shipping weight is 1 lbs (0.45 kg).
Installation notes on the drawing: when mounting to a plane surface, maintain a spacing through air of not less than 1/4 in between the supporting surface and enclosure, install in a metal box only, and use wire rated for at least 105 °C. The primary leads are 9.0 in long.
The BC2G is UL listed (#E184371) and CSA certified (209651), and is built to a 105 degree temperature design. It is also REACH and RoHS compliant.
