Product details

63 A AC, 4 NC — the normally-closed load switch for always-on circuits

The Siemens 5TT5853-0 is a SENTRON Insta contactor built around a 63 A AC rated operational current and a 4 NC contact configuration — meaning it stays closed when the coil is de-energized, intended for circuits that must remain connected unless actively commanded to open.

Panel fit and thermal spacing

The 5TT5853-0 occupies 3 modular width units on a DIN rail, with dimensions of 54 mm wide, 90 mm tall, and 71 mm deep. The installation note requires spacers between units to ensure adequate heat dissipation — at 63 A the power loss is 8 W per pole in the hot operating state, so the thermal budget in a crowded enclosure needs attention. IP20 rated — suitable for dry indoor panel environments only.

Frequently asked questions

Is Siemens 5TT5853-0 suitable for 3-phase motor control?

The 5TT5853-0 is a 4-pole contactor with all NC contacts, rated 63 A at 440 V maximum. It can switch a 3-phase motor load within those ratings, but the normally-closed contact configuration means the motor is connected when the coil is off — verify this logic suits your safety circuit before specifying.

What is the difference between Siemens 5TT5853-0 and 5TT5854-0?

The 5TT5853-0 has 4 NC contacts and 0 NO contacts; the 5TT5854-0 carries a different contact arrangement. Confirm the contact configuration on the 5TT5854-0 datasheet before substituting.

How can I order Siemens 5TT5853-0?

The 5TT5853-0 is sourced to order against an RFQ through independent distribution channels. Submit a request for quote to confirm current pricing and availability.
