3RT1916-1LM00 Product Description

The Siemens 3RT1916-1LM00 is a high-quality interference suppression diode designed to enhance the performance and reliability of Size S00 contactors. This compact component, measuring just 9 x 28 x 32 mm, is engineered to operate within a DC voltage range of 24 to 70 volts. It is specifically crafted to mitigate voltage spikes and electrical noise, ensuring smoother operation and extending the lifespan of the contactor it is paired with.

The inclusion of an LED provides immediate visual feedback on the operational status, which is particularly useful for maintenance and troubleshooting in industrial environments. The 3RT1916-1LM00 is a testament to Siemens' commitment to innovation and quality, offering a simple yet effective solution to protect sensitive electrical systems from disruptive interference. Its straightforward mounting design allows for quick and easy installation onto the contactor, making it a convenient choice for engineers looking to maintain optimal performance in their electrical circuits.

Frequently Asked Questions

What is the function of an interference suppression diode?

An interference suppression diode is used to protect a circuit from voltage spikes caused by the inductive load of a contactor coil. When the contactor is de-energised, the diode suppresses the transient voltage spike, preventing potential damage to other components in the circuit.

Can this diode be used with any size S00 contactor?

Yes, the Siemens 3RT1916-1LM00 is specifically designed for use with size S00 contactors, providing effective suppression of voltage transients.

What voltage range can the diode handle?

The diode is suitable for a DC voltage range of 24 to 70 volts, making it versatile for various applications within its specified voltage limits.

How is the diode installed onto a contactor?

The diode is designed for easy mounting onto a contactor. It typically clips onto the contactor or is connected via terminals, depending on the specific design of the contactor.

What are the dimensions of the diode?

The diode measures 9 x 28 x 32 mm, making it compact and suitable for installation in tight spaces where contactors are used.

Is there any special handling required for this diode?

While no special handling is required, it is important to observe polarity when installing the diode and to ensure it is securely attached to prevent any malfunction.

How does the diode contribute to the longevity of a contactor?

By suppressing voltage spikes, the diode reduces wear and tear on the contactor's contacts and other electrical components, which can extend the overall lifespan of the contactor.

Can this diode be used in conjunction with other protective devices?

Yes, the diode can be used alongside other protective devices such as varistors or RC circuits to provide comprehensive protection against electrical transients.
