The ABB Stotz S&J EN Installation Relay EN25-31N-01 is a 4-pole relay with a width of 36 mm that controls 3-phase loads up to 25 A. It is available in various contact configurations and coil voltages, making it suitable for switching electric 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, allowing for hum-free and quiet switching.

The EN25..N features an integrated switch to choose between three operating modes: manually off (even with the control signal present), automatic operation (normal relay function), and manually on with a return to automatic operation once the coil is powered again. This allows for a functional test of the load circuit without a control signal and a quick shutdown of the load circuit when a control signal is present.

An auxiliary switch that can be mounted on the left side, along with sealing caps and a spacer, complements the range. The EN25..N has an installation design and meets the household standard EN61095, making it particularly suitable for panel installation.
