Voltage peaks are dangerous for machines and plants. The solution is so simple: suppressor components from Murrelektronik. They help plants, machines, and equipment to meet EMC requirements. They also extend the service lives of electronic and electrical units at low cost.
Voltage peaks of up to several kV occur when inductive loads, such as motors, switchgear, or valves, are switched off. This has numerous negative effects: They reduce the service life of switch contacts; there is a drastic increase in coil shorts; faults occur in the control sequence; switchgear suffer defects.
On the upside, voltage peaks can be limited. When suppressor modules from Murrelektronik are fitted in the direct vicinity of the fault source, the peaks are much shorter. This extends the service lives of contacts and coils. And the plant operator is delighted with the increase in operational reliability and plant availability.
Murrelektronik works closely with switchgear manufacturers in the development of suppressor components. The modules are precisely tuned to each individual type and they fit precisely in the mechanical environment. This guarantees optimized suppression.
The motor suppressor modules from Murrelektronik come in a wide range of casing types and several fixing options. For example, they can be fitted in motor terminal boxes, switch cabinets, DIN mounting rails, or even on the underside of switchgear. Suppressor modules for motors are specially important in machines and plants that use fieldbus systems since voltage peaks pose an enormous risk for buses, often leading to their destruction. Murrelektronik also offers the right products for all connection types. In addition, the product portfolio includes a wide range or universal suppressor modules that cover all possible applications.
By the way, Murrelektronik has also cooperated for over 30 years with renowned switchgear manufacturers who have successfully marketed suppressor modules from Oppenweiler as OEM products.
