The Siemens 5TT5502 is a SENTRON remote control switch rated at 16 A for a 400 V AC supply, with 2 normally open contacts.
The 16 A rating holds at cos φ 0.6, so this switch handles inductive loads like small motor contactor coils or solenoid valves at that power factor without derating. The 400 V AC supply voltage is fixed — single-voltage, not a range — so confirm your line voltage matches exactly. Two NO contacts give you a single-pole double-throw equivalent for on/off control of one load circuit.
Deployment Context
The 90 mm height and 55 mm installation depth fit standard enclosure clearances; one width unit (roughly 18 mm) leaves adjacent slots for other modular devices. Use it as a remotely operated contactor for lighting, heating, or small motor loads where a latching relay keeps state after a control pulse.
