2-pole contactors EN20..N with an overall width of 18 mm control 1-phase loads up to 20 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. EN20..N have an integrated switch for choosing between three operating modes: manually switched off (even when a control signal is present), automatic operation (normal contactor function) and manually switched on with a return to automatic operation as soon as the coil is next supplied with voltage. This offers numerous advantages: for example, a function test of the load circuit can be carried out during commissioning even without a control signal, and the load circuit can also be switched off quickly and easily at any time when a control signal is present. An auxiliary switch that can be attached to the left as an accessory completes the range. EN20..N have installation design and meet the household standard EN61095, among others, they are therefore particularly suitable for distribution board installation.
