It terminates wires via a screw-rising cage clamp — turn the M3 screw, the clamp rises inside the housing and cinches the conductor against the current bar. Rated 13.5 A at 300 V, it handles typical control and low-power distribution circuits. The green polyamide housing is the standard colour for this Buchanan series, and the side interlocking feature lets you snap multiple blocks together into a multi-position assembly without a separate jumper bar. The 5.08 mm pitch sets the terminal spacing on the PCB — centre-to-centre distance between adjacent screw holes. That is wide enough for 16 AWG wire (the largest the block accepts) without crowding adjacent terminals. The M3 screw torque spec of 0.68 Nm (6 Lb-In) is the factory-recommended value — overtightening can strip the brass threads or crack the housing. ## Wiring and Termination — Screw-Rising Cage Clamp The 282837-4 uses a screw-rising cage clamp: the M3 screw turns and lifts a brass, nickel-plated clamp inside the terminal cavity. The clamp presses the stripped wire against the tin-plated brass current bar. Accepts 16 to 28 AWG solid or stranded wire. The interlocking side feature allows ganging multiple 282837-4 blocks side-by-side into a single assembly; the interlock keys align the blocks and prevent separation under vibration. The base product number is 282837, covering the full series of pitch and position variants.","metaTitle":"TE Buchanan 282837-4 Terminal Block, 4 Position, 5.08mm","metaDescription":"TE Connectivity Buchanan 282837-4 terminal block, 4 positions, 5.08 mm pitch, 13.5 A, 300 V.
