Danfoss TWA-A electrothermal actuator, 24 V AC, normally closed, 10 m cable (088H3117)

Part Number
088H3117 · HS 8481.90

Danfoss TWA-A electrothermal (thermal-wax) valve actuator, OEM order code 088H3117. 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 24 V AC (50/60 Hz), power consumption 2 W. RA snap-on connection; fits Danfoss RA valve bodies and RA-connection manifold valves. 10 m connecting cable. Enclosure rating IP41. Net weight 0.446 Kilogram. Genuine Danfoss part; technical data quoted verbatim from store.danfoss.com (code 088H3117). OEM P/N 088H3117, EAN 5702420072715.
