Danfoss TWA-A electrothermal actuator, RA connection, 230 V AC, normally closed, 1.15 m cable

Danfoss TWA-A electrothermal (thermal-wax) valve actuator, OEM order code 088H3250. The TWA-A converts a switching signal from a room thermostat or controller into valve movement on hydronic floor-heating manifolds and radiator/zone valves — no auxiliary air or hydraulics. Normally closed (NC) — the valve is closed when de-energised and opens when the actuator is powered. Supply voltage 230 V AC (50/60 Hz), power consumption 2 W. RA connection. 1.15 m connecting cable. Enclosure rating IP41. Net weight 0.13 Kilogram. Genuine Danfoss part; technical data quoted verbatim from store.danfoss.com (code 088H3250). OEM P/N 088H3250.
