The Siemens SENTRON 5TT5750-2 is an Insta contactor with four normally-open (NO) contacts and zero NC contacts, rated for 63 A at 230 V or 400 V AC, with a 24 V AC/DC coil. The 24 V AC/DC coil keeps it compatible with standard control voltages found across most industrial and building automation panels. That 54 mm width is the same as a standard miniature circuit breaker, so it slots into existing SENTRON sub-distribution boards without re-spacing the rail.

Product details
Frequently asked questions
What are the key ratings of the 5TT5750-2?
It is a 4 NO contactor rated 63 A at 230/400 V AC with a 24 V AC/DC coil. It measures 71 mm deep, 54 mm wide, 90 mm tall, with an installation depth of 64 mm, and carries an IP20 protection class.
Where can I buy the 5TT5750-2?
This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
Will the 5TT5750-2 fit in a panel designed for a 5SL4363-7 miniature circuit breaker?
Both share the same 54 mm width and 3 width units, so the contactor occupies the same DIN-rail footprint as the 5SL4363-7. However, the 5TT5750-2 is a contactor (switching load) while the 5SL4363-7 is a miniature circuit breaker (overcurrent protection) — they serve different functions, so a direct swap without rewiring is not possible.
