ABB 2TAZ312001R2043 Impulse Relay E294/24 OFF/ON 24V AC

ABB 2TAZ312001R2043 is an E294/24 latching (impulse) relay from the E290 range for energy-efficient centralised lighting control. The device is electromagnetically operated: a brief 24 V AC coil pulse latches the internal main contacts mechanically, so each impulse-button press toggles the relay state. It is rated at 250 V AC / 1 A, one module (18 mm) wide, in RAL 7035 light grey, and is intended for buildings where lighting must be controlled from three or more locations. Sold in packs of five.
