4-pole contactors ESB40..N with a width of 54 mm control 3-phase loads up to 40 A (Ö-contacts up to 30 A) and are available in various contact configurations and coil voltages. They switch electrical heating devices, water heaters, motors for pumps, ventilation, and other drives as well as lighting. Due to an integrated coil circuit, they operate with both AC and DC control voltages. Therefore, the devices are completely hum-free and quiet when switching. An auxiliary switch that can be mounted on the left side, along with sealing caps and a spacer, complement the range. ESB40..N features installation design and complies with the household standard EN61095, making them particularly suitable for panel installation.
