4-pole EN40 contactors 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 absolutely hum-free and quiet when switching. , EN40 have an integrated switch for choosing between three operating modes: manually switched off (even when a control signal is present), automatic mode (normal contactor function) and manually switched on with a return to automatic mode 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. , Accessories such as auxiliary switches, sealing caps and a spacer complete the range., EN40 have installation design and meet the household standard EN61095, among others, they are therefore particularly suitable for distribution board installation.
