ABB Stotz S&J EN Installation Relay EN40-40N-06: further details
4-pole relays EN40..N with a width of 54 mm control 3-phase loads up to 40 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 buzz-free and quiet when switching. EN40..N features an integrated switch to choose between three operating modes: manually off (even with control signal present), automatic operation (normal relay function), and manually on with a return to automatic operation as soon as the coil is powered again. This offers numerous advantages: for example, during commissioning, a functional test of the load circuit can be performed even without a control signal, and the load circuit can be quickly and easily switched off at any time with an existing control signal. An auxiliary switch that can be mounted on the left side, along with sealing caps and a spacer, complements the range. EN40..N has an installation design and meets, among others, the household standard EN61095, making them particularly suitable for panel installation.
