ABB Stotz S&J Installation Relay ESB25-20N-01: additional details
The 2-pole relays EN25..N with a width of 36 mm control loads up to 25 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. Thanks 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. EN25..N features an integrated switch to choose 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 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 turned off at any time with an existing control signal. An auxiliary switch that can be mounted on the left side as an accessory, as well as sealing caps and a spacer, complement the range. EN25..N has an installation design and meets, among others, the household standard EN61095, making them particularly suitable for panel installation.
