Selection Notes
With the 20D controller built in, this unit is self-supplied and needs no separate transfer-logic panel, unlike larger changeover switches that pair a bare mechanism with external control wiring. DIN-rail or base mounting gives flexibility in small distribution boards where the 233 x 103 x 131 mm footprint has to fit a standard enclosure. Pick this 2-pole 220-240 V version for single-phase or line-neutral transfer; a 3-pole 400 V unit covers three-phase sources in the same compact frame.
