4-pole contactors EN40..N with a width of 54 mm control 3-phase loads up to 40 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. EN40..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, during commissioning, a function test of the load circuit can be carried out 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 mounted on the left as an accessory, as well as sealing caps and a spacer complete the range. EN40..N have an installation design and meet the household standard EN61095, among others, so they are particularly suitable for installation in distribution boards.
