The ABB Stotz S&J EN Installation Relay EN20-20N-06 is a 2-pole relay with a width of 18 mm that controls single-phase loads up to 20 A. It is available in various contact configurations and coil voltages and is used to switch electrical heating devices, water heaters, motors for pumps, ventilation, and lighting. Thanks to an integrated coil circuit, it operates with both AC and DC control voltages, making it buzz-free and quiet during switching.

The EN20-20N features an integrated switch to select between three operating modes: manually off (even with an applied control signal), automatic operation (normal relay function), and manually on with a return to automatic operation as soon as the coil is supplied with voltage again. This allows for functional testing of the load circuit without a control signal and quick disconnection of the load circuit when a control signal is present. An auxiliary switch that can be mounted on the left side as an accessory complements the range.

The EN20-20N has an installation design and meets the household standard EN61095, making it particularly suitable for panel installation.
