The Siemens 5TT5800-2 is a SENTRON INSTA modular contactor designed for reliable switching of AC loads in distribution boards and control panels. It features 2 normally open (NO) contacts with a rated operating current of 20 A and is actuated by a 24 V AC control supply. The device is suitable for switching typical building and light industrial circuits such as lighting, heating, and general load control, including incandescent lamp loads up to 1,000 W.
Built in a compact 1-module (18 mm) format for DIN rail mounting, the 5TT5800-2 offers IP20 protection and an installable design that supports supplementary accessories where required. The unit does not include a manual operating slide. Dimensions are approximately 90 mm high, 18 mm wide, and 71 mm deep (mounting depth 64 mm).

| Part Description | Siemens 5TT5800-2 SENTRON INSTA modular contactor with 2 normally open contacts, designed for switching AC loads at 230 V with a 24 V AC control input. Rated at 20 A with a compact 1-module width format for DIN-rail electrical assemblies. |
What does this modular contactor do?
It is a DIN-rail mounted modular contactor designed to switch electrical loads using a low-voltage control signal. This model provides two normally-open (NO) power contacts that close when the coil is energized.
How many poles/contacts does it have?
It has 2 normally-open (NO) contacts and no normally-closed (NC) contacts.
What coil/control voltage is required to energize it?
The control supply (coil) is 24 V AC rated.
What load voltage range is it intended to switch?
It is intended for switching AC loads typically in the 230 V AC class, and it is commonly used in 230/400 V AC installations (application dependent on wiring and system design).
What is the rated switching current?
The rated operating current is 20 A.
Can it be used for lighting loads?
Yes. For incandescent/filament lamp loads, the stated switching capacity is 1,000 W (application dependent).
Does it include a manual override lever or slide?
No. This unit does not include a slide for manual operation.
What is the ingress protection rating?
The protection class is IP20, meaning it is intended for installation inside an appropriate enclosure.
What are the physical dimensions?
Typical dimensions are approximately 90 mm (H) x 18 mm (W) x 71 mm (D), corresponding to 1 modular width unit.
Is it suitable for standard DIN-rail distribution boards?
Yes. It is a 1-module wide device intended for mounting in modular distribution boards and control panels.
Are there any installation considerations for heat dissipation?
Yes. Provision should be made for spacers to help ensure heat dissipation, especially when operating near rated current.
What is the typical power dissipation during operation?
Power loss is specified at about 1.7 W per pole at rated current in hot operating state.
Can auxiliary or supplementary devices be fitted?
Yes. The product is designed to allow installation of supplementary devices (depending on the accessory and application). If you need help matching an accessory to the base unit, reference the Siemens 5TT5800-2 part number in your internal notes.
- Switching and isolating lighting circuits (including incandescent loads) from a low-voltage control signal
- Controlling electric heating loads in building and panel applications where a compact modular device is needed
- General-purpose remote switching of single-phase AC loads on DIN rail in distribution boards and control cabinets
- Interface switching between low-voltage control circuits (24 V AC coil) and higher-voltage power circuits (230/400 V AC)
- Timed or automated load control when driven by external controls such as timers, sensors, or building automation outputs
- Energy management applications where selected circuits are switched on/off according to schedules or demand signals
- Control of small motors, pumps, and fans within the contactor’s rated current and duty requirements
- Load shedding and priority switching of non-essential circuits in commercial or industrial electrical installations
- Centralized control of multiple branch circuits using a modular contactor with multiple normally-open poles
- Panel retrofits and upgrades where a narrow 1-module-width contactor helps conserve space on DIN rail assemblies
