EATON DC Surge Suppressors
Eaton DC surge suppressors protect electrical systems against damage caused by voltage spikes and surges during lightning strikes or power outages. They are used in conjunction with other electrical assemblies, such as panelboards, switchboards, motor control centres, low-voltage switchgear, au...tomatic transfer switches and bus plugs.Read more
AWorking Mechanism
- These suppressors feature a metal oxide varistor (a type of voltage-limiting component) to absorb the surge energy.
- Metal oxide varistors (MOVs) bring the voltage and current to safe levels, preventing the surge from reaching the electrical system and causing damage.
- The excess energy absorbed is then safely dissipated, thus increasing the reliability and longevity of electrical devices for operation in harsh environments.
Frequently Asked Questions
How does a MOV work in these suppressors?
When a surge occurs, the MOV acts as a shunt, diverting the excess current from the electrical system. The MOV's resistance changes with the voltage level, allowing it to effectively limit the voltage across the component. Once the surge has passed, it returns to its normal resistance, allowing the electrical system to work normally.
How to install a surge suppressor in a relay?
- Determine the type of surge suppressor required for the relay.
- Collect necessary tools, such as wire cutters, strippers and crimping tools that would be needed during the installation.
- Connect the suppressor to the relay by splicing it into the power supply wires.
- Connect the MOV to the surge suppressor using the appropriate wiring connections. The MOV should be connected in series with the relay.
- Once the MOV and the suppressor have been connected, test the installation to ensure that both these components are functioning properly.
- Secure the suppressor and MOV in place using cable ties and ensure that they do not interfere with the operation of the relay.
- Label the installation to indicate that a surge suppressor has been installed.
