ABB KSD211B 3BHE022455R1101 switch protection relay

Electrical parameters

1. Rated voltage

Common rated voltage specifications include 24V DC, 110V AC, 230V AC, etc. Different rated voltages can be adapted to different application scenarios and power systems.

2. Rated current

The rated current generally ranges from a few amperes to several tens of amperes, such as 5A, 10A, 16A, etc., depending on the design purpose and load capacity of the relay.

3. Power consumption

During operation, power consumption is usually at a low level, possibly around a few watts, such as 2-5 watts, which helps to reduce energy loss.

4. Coil resistance

The coil resistance may vary depending on the rated voltage and design requirements, for example, for products with 24V DC, the coil resistance may be around a few 

hundred ohms.

performance parameter 

1. Action time

The action time is usually within a few tens of milliseconds, and a fast action time can ensure timely response in case of circuit abnormalities, such as possibly 10-30ms.

2. Release time

The release time is also relatively short, usually in the range of tens of milliseconds, about 15-40ms, to ensure that the relay can quickly return to its initial state.

3. Electrical lifespan

The electrical lifespan is relatively long, usually reaching over 100000 operating cycles, which means it can work stably and reliably for a long time, adapting to frequent 

switching operations.

4. Mechanical lifespan

The mechanical lifespan can reach millions of times, such as 1 million to 10 million times, which reflects the stability and durability of its mechanical structure.

Environmental parameters

1. Operating temperature range

It can work normally in a wide temperature environment, with a working temperature range generally from -25 ° C to+70 ° C, and can adapt to temperature changes in 

different regions and working conditions.

2. Storage temperature range

The storage temperature range may be wider, such as -40 ° C to+85 ° C, to ensure that the product is not affected by temperature during transportation and storage.

3. Relative humidity

The relative humidity range is usually 5% -95% (without condensation), and it can maintain good performance in different humidity environments.

Other parameters

1. Protection level

The protection level may reach IP20 or higher, which can prevent contact with foreign objects such as fingers and provide a certain level of safety protection for operators.

2. Installation method

Generally supports rail installation or panel installation, making it convenient for users to install flexibly according to their actual needs.
