ABB Stotz S&J EN Installation Relay EN20-20N-01: Additional Details
2-pole relays EN20..N with a width of 18 mm control single-phase loads up to 20 A and are available in different contact configurations and coil voltages. They switch electric heating devices, water heaters, motors for pumps, ventilation, and other drives, as well as lighting. Thanks to an integrated coil circuit, they operate with both AC and DC control voltages. Therefore, the devices are completely buzz-free and quiet during switching. EN20..N features an integrated switch to select between three operating modes: manually off (even with a 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 also be quickly and easily turned off at any time with a control signal present. An auxiliary switch that can be mounted on the left side as an accessory complements the range. EN20..N have an installation design and comply with the household standard EN61095, making them particularly suitable for panel installation.
