The Siemens 5TT5041-2 is a SENTRON Insta contactor with 3 normally-open and 1 normally-closed main contacts, rated for 400 V AC and 40 A. At 3 modular width units (53.5 mm wide, 90 mm tall, 71 mm deep), it occupies three adjacent 18 mm slots on a standard DIN rail. The installation note calls for spacers between units to allow heat dissipation, so plan for a 4 W per-pole power loss when grouping multiple contactors in a row.
The 5TT5041-2 is rated 400 V AC, 40 A, with a 24 V AC/DC coil. It has 3 normally-open and 1 normally-closed contacts, occupies 3 modular width units (53.5 mm), and has an IP20 protection class.
The 5TT5041-2 is sourced and quoted to order against an RFQ through independent industrial automation distribution. Availability and current pricing are confirmed at quote time.
This Insta contactor is used for switching loads up to 40 A at 400 V AC in DIN-rail control panels — typical applications include lighting control, small motor switching, and resistive heater banks in commercial and industrial installations.
