ABB EN40-20N-01 Remote switch 2 makers 40 A 1 pc(s)

4-pole contactors EN40 with 54 mm width controls 3-phase loads up to 40 A and are available in different contact positions and coil voltages. They control electrical heaters, water heaters, motors for pumps, ventilation and other drives as well as lighting. Through an integrated coil circuit they work with AC as well as with DC control voltages. The devices are therefore absolutely free of humming and low while switching. EN40 have an integrated switch for selecting between three operating modes: Manually switched off (even when the control signal is present), automatic mode (normal contactor function) and manually switched on with return to automatic mode as soon as the coil is next supplied with power. This offers numerous advantages: For example, a function test of the load circuit can be carried out even without control signal during commissioning, and the load circuit can be switched off quickly and easily at any time if a control signal is available. Accessories such as auxiliary switches, sealing caps and a spacer complement the range. EN40 have an installation design and meet the household standard EN61095 and are therefore particularly suited to distributor installation.
