AEG Miniature Circuit Breaker ELFA-E82S-D4 415V Allis-Chalmers

The AEG Elfa E82S-D4 is a 2-pole DIN rail mount miniature circuit breaker rated at 4 amps with a D-curve trip characteristic. The nameplate confirms a voltage rating of 415V AC and an interrupting capacity of 10,000 amps (10 kA), consistent with the E82S series specifications. The D-curve designation indicates a high magnetic trip threshold, typically 10 to 20 times the rated current, making this unit suited for loads with high inrush characteristics such as transformers or solenoid-type devices.

The unit features a two-pole configuration with screw terminal connections accessible at both the top and bottom of the body. Standard 35mm DIN rail mounting clips are integrated into the base. Terminal markings on the housing indicate poles 1 through 4, with input connections at the top and load connections at the bottom. The device carries VDE certification as shown on the nameplate label.

The E82S series was manufactured by AEG under its Elfa product line for industrial and machine tool applications in European and international markets. The part number ELFA-E82S-D4 reflects the series designation (E82S), trip curve (D), and ampere rating (4). Overall physical construction is consistent with standard IEC 60898 type miniature circuit breaker form factor.
