Product information

Description

The Siemens 5TT4201-0 installation relay is a robust electrical component engineered for the reliable switching of circuits in both residential and industrial environments. Designed to handle a rated current of 16A, this device features a single normally open (1NO) contact configuration and operates on a 230V AC control voltage. It serves as an essential element in modern electrical distribution systems, providing consistent performance for automated lighting, heating, and ventilation control.

Advantages

This installation relay stands out due to its high operational reliability and compact design, which allows for space-saving installation within standard distribution boards. The device is built to withstand frequent switching cycles, ensuring longevity and minimal maintenance requirements. Its standardized design ensures compatibility with common electrical infrastructure, while the high-quality materials used in its construction provide excellent thermal stability and electrical safety during continuous operation.

Suitable for

Automated lighting control systems
Heating and ventilation circuit management
Industrial automation processes
Residential electrical distribution boards

When it may not be suitable

This relay is not intended for applications requiring high-frequency switching beyond its specified mechanical and electrical endurance limits. It is also not suitable for direct current (DC) applications or circuits exceeding the 16A rated current capacity.

Key specifications

Rated current: 16A
Contact configuration: 1NO (Normally Open)
Control voltage: 230V AC
Mounting type: DIN rail

How to use

The installation relay is designed for mounting onto a standard DIN rail within an electrical distribution cabinet. Ensure that the power supply is disconnected before installation. Connect the control circuit wires to the designated coil terminals and the load circuit wires to the switching contact terminals, ensuring that the voltage and current ratings are strictly adhered to. Once installed, verify the connections and test the switching function by energizing the control circuit.

What to consider before purchase

Verify that the control voltage matches your existing system (230V AC).
Ensure the load current does not exceed the 16A limit.
Check available space on the DIN rail within your distribution board.
Confirm that a single normally open contact meets your specific circuit requirements.

Usage recommendations

For optimal performance and safety, ensure that the relay is installed in a dry, dust-free environment and that all terminal connections are tightened to the manufacturer's specified torque settings. Regular inspection of the electrical connections is recommended to maintain system integrity.
