Product details

The Siemens SENTRON 5TT5033-0 is an Insta contactor with four normally-closed (NC) contacts and no normally-open contacts — a dedicated NC-only switching block. It is rated for 25 A at 230 V AC (operational current) and can handle a maximum of 400 V AC. The coil actuation accepts both AC and DC (rated 230 V AC / 220 V DC), making it flexible for control circuits that may be either. The IP20 enclosure means it is intended for installation inside a panel or enclosure where it is protected from direct contact and large debris, but not from moisture or dust ingress.

Its dimensions are 90 mm high, 35 mm wide, and 71 mm deep, with an installation depth of 64 mm. In a crowded DIN rail, skip a slot or use a vented separator.

Frequently asked questions

Where can I buy 5TT5033-0?

The 5TT5033-0 is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

What is the difference between 5TT5033-0 and a miniature circuit breaker like 5SL4363-7?

The 5TT5033-0 is an Insta contactor — a switching device for controlling loads — while the 5SL4363-7 is a miniature circuit breaker (MCB) for overcurrent protection. They are not functional substitutes; the contactor switches, the breaker protects. If your panel was specified around the 5SL4363-7, the 5TT5033-0 will not drop in without rewiring because they serve different roles.

Does the 5TT5033-0 require any special installation considerations?

Yes, the manufacturer specifies that spacers must be provided between adjacent devices to ensure heat dissipation, given the 2.2 W power loss per pole at rated current.
