The Siemens 5TT4111-2 is a SENTRON remote control switch designed for DIN rail installation in low-voltage electrical distribution systems. It features one normally open contact rated for 230 V AC and 16 A, with 24 V DC control, making it suitable for remotely switching lighting and similar electrical loads from control circuits.
Built with a mechanical latching relay design, the 5TT4111-2 supports direct operation and includes a switch position indicator for clear status visibility. It provides galvanic isolation between the magnet coil and contact, helping to separate the control and load sides of the circuit. The unit offers a minimum pulse duration of 50 ms and an electrical endurance of 50,000 switching cycles.
This compact modular device occupies one width unit and is intended for mounting on a standard DIN rail. It has four terminals and accepts both rigid and flexible conductors from 1 mm² to 6 mm², with screw-type terminals requiring a tightening torque of 0.8 to 1 Nm. With a mounting height of 90 mm, installation depth of 70 mm and IP20 protection when conductors are connected, it is well suited for use in control panels, distribution boards and building electrical installations.

What type of component is this?
It is a SENTRON remote control switch with a mechanical latching relay design. It has one normally open contact and is intended for switching 230 V AC loads up to 16 A using a 24 V DC control signal.
What does a remote control switch do in an electrical installation?
A remote control switch allows a load to be switched from one or more control points using a pulse signal. In this case, the device is designed for direct operation and uses a mechanical switching mechanism to maintain its state after the control pulse.
What contact configuration does this device use?
The device has 1 normally open contact, 0 normally closed contacts and 0 changeover contacts. This makes it suitable for simple on/off switching applications where the circuit is closed when the contact is actuated.
What control voltage is required?
The control circuit is rated for 24 V DC. The stated operating range is 19.2 V DC to 26.4 V DC, with a minimum pulse duration of 50 ms.
What is the rated switching current?
The rated switching current is 16 A. The device is also rated for 16 A at cos phi 0.6, making it suitable for a range of AC load types within the stated rating.
What load types can it switch?
The device can switch several common electrical load types, including filament lamp loads up to 2,000 W, uncompensated fluorescent lamp loads up to 500 VA, fluorescent lamp loads with parallel compensation up to 400 VA and fluorescent lamp loads with DUO circuit up to 900 VA.
How is the device mounted?
It is designed for DIN rail mounting. The mounting position can be any orientation, and the device occupies 1 width unit.
What are the main installation dimensions?
The mounting height is 90 mm and the installation depth is 70 mm. The device has 4 terminals and a net weight of approximately 135 g.
What conductor sizes can be connected?
The terminals accept flexible conductors with core end processing from 1 mm² to 6 mm², and rigid conductors from 1 mm² to 6 mm². The stated tightening torque range for the screw-type terminals is 0.8 N·m to 1 N·m.
What environmental rating does it have?
The device has an IP20 protection class when conductors are connected. Its specified ambient operating temperature range is -10 °C to 40 °C.
Does it provide isolation between the control and load circuits?
Yes. The datasheet specifies galvanic isolation between the magnet coil and the contact, helping to separate the 24 V DC control side from the switched contact side.
Does it include a switch position indicator?
Yes. The device includes a switch position indicator, allowing the switching state to be checked visually during inspection or commissioning.
