4-pole contactors ESB25..N with a width of 36 mm control 3-phase loads up to 25 A and are available with different contact assignments and coil voltages. They switch electric heaters, water heaters, motors for pumps, ventilation and other drives as well as lighting. Thanks to an integrated coil circuit, they work with both AC and DC control voltages. The devices are therefore completely hum-free and quiet when switching. An auxiliary switch that can be attached to the left as an accessory, as well as sealing caps and a spacer complete the range. ESB25..N have an installation design and meet the household standard EN61095, among other things, making them particularly suitable for installation in distribution boards.
