Product details

Siemens SENTRON Insta Contactor 5TT5030-8

The coil is 24 V DC, so it's a straight drop for a PLC or relay output that needs to switch a resistive or lightly inductive load — lighting, small heaters, solenoid valves. It fits a standard DIN-rail enclosure and takes up two modular width units (about 35 mm wide).

The 25 A AC rating is the maximum continuous current the main contacts can carry in AC-1 duty (resistive load). For motor or inductive loads, you'll want to derate — a contactor this size is not a motor starter.
