Product details

Mounting height is 90 mm and installation depth is 55 mm, which matches the standard SENTRON modular-device footprint. If you're swapping out an older contactor-based remote switch in a panel that was laid out for 5SL-series breakers, the 5TT5512 will drop into the same DIN slot without needing to re-drill the gland plate or re-route the wiring — the terminals land in the same plane.

Rated current holds at 16 A even at cos φ 0.6, so the inductive load capability is solid for switching contactor coils, solenoid valves, or small motor starters remotely. The control voltage is AC, and the supply frequency is 50 Hz — confirm the coil rating matches your control circuit before wiring.

Frequently asked questions

What is the 5TT5512 rated for?

Rated 16 A at 400 V AC, 50 Hz, with 2 normally-open contacts. The 16 A rating holds at cos φ 0.6, so it handles inductive loads without derating.

Where can I buy the 5TT5512?

Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

Will the 5TT5512 fit in a panel designed for a 5SL4363-7?

Yes, the mounting height (90 mm) and DIN-rail footprint match the 5SL-series miniature circuit breakers. The 5TT5512 is one width unit wide versus three for the 5SL4363-7, so it takes less rail space. No rewiring of the gland plate or terminal layout is needed.
