The Siemens SENTRON 5TT5001-8 is an Insta contactor with one normally-open and one normally-closed contact, designed for DIN-rail mounting in distribution panels. The coil is rated for 230 V AC, and the control circuit accepts 24 V DC — a split-voltage arrangement that lets the contactor switch a 230 V AC load while being commanded by a 24 V DC PLC or relay output.
Dimensions and mounting
The housing is 17.5 mm wide (one modular unit), 90 mm tall, and 71 mm deep, with an installation depth of 64 mm. The IP20 rating means it is protected against solid objects larger than 12 mm but not against moisture — standard for enclosed panel mounting. The manufacturer notes that spacers are required between units to ensure adequate heat dissipation; the per-pole power loss at rated current in hot operating state is 1.7 W.
Lifecycle and sourcing
The product status is Active per the manufacturer's lifecycle record. This part is sourced and quoted to order against an RFQ through independent distribution; availability and current pricing are confirmed at quote time.
