IK9171.11-200 DOLD Undervoltage Relay

Review DOLD Ik9171.11/200 Undervoltage Relay 3ac 400/230v 50/60hz 5a Used

The Dold IK9171.11/200 Undervoltage Relay is a versatile and essential electrical component designed to protect 3-phase electrical systems from voltage drops below the specified level. This relay operates effectively within voltage ranges of 400V to 230V and frequencies of 50Hz and 60Hz.

The IK9171.11/200 is a Type 2 undervoltage relay with a current capacity of 5A. Its compact size and robust design make it suitable for various industrial applications. This undervoltage relay is equipped with a normally open contact, which closes when the voltage level drops below the set point. This feature allows for the activation of backup systems or the interruption of power to prevent damage to equipment during voltage fluctuations.

The Dold undervoltage relay is designed and manufactured to meet the highest standards of electrical safety and reliability. It is constructed using high-quality materials and advanced manufacturing techniques to ensure long-lasting performance. The relay housing is made of a durable and impact-resistant material, making it suitable for use in harsh environments.

Installation of the IK9171.11/200 is straightforward, with clear instructions provided in the user manual. The relay can be mounted on a DIN rail or directly onto a suitable surface using the provided mounting hardware. The terminal connections are easily accessible, allowing for quick and secure wiring.

The Dold IK9171.11/200 Undervoltage Relay is an essential component of any industrial electrical system, providing protection against voltage drops and ensuring the reliable operation of critical equipment. With its robust design, wide voltage range, and easy installation, this relay is an ideal choice for a variety of applications.

The Dold IK9171.11/200 Undervoltage Relay is a type of protective device used to disconnect a load from the power supply when the voltage falls below a certain level. Here are some pros and cons of buying this particular model:

1. Wide voltage range: This relay can be used with both 230V and 400V power supplies and functions at 50Hz and 60Hz.

2. Compact size: Despite its wide voltage range, the relay has a compact size, making it suitable for installation in confined spaces.

3. Low power consumption: With a maximum current rating of 5A, this relay has a low power consumption, which can help reduce energy costs.

4. Robust design: The relay is designed to withstand harsh industrial environments, making it suitable for use in various applications.

5. Easy installation: The relay comes with clear markings and easy-to-understand instructions, making it easy to install for users with little to no experience.

1. Limited load capacity: With a maximum current rating of 5A, this relay may not be suitable for applications with high load requirements.

2. Lack of remote mounting option: The relay must be mounted directly on the load circuit, which may not be convenient for some installations.

3. No built-in overload protection: This relay only disconnects the load when the voltage falls below a certain level. It does not provide overload protection, which may be a concern for some users.

In conclusion, the Dold IK9171.11/200 Undervoltage Relay is a suitable option for applications that require a compact, low-power consumption, and versatile undervoltage protection device. However, it may not be suitable for applications with high load requirements or those that need remote mounting or overload protection.

If you are looking for an undervoltage relay with a higher load capacity, consider models with a current rating of 10A or more. If you require remote mounting, look for models with this feature. If you need both undervoltage and overload protection, consider combining this relay with an overload relay or using a protective device that offers both functions in one.
