Cost-saving design by reducing components
Systematically reducing of components is a major reason for a successful cost-saving design. Obvious, yet often overlooked: Already at the power input of a machine or device, the number of components used can be significantly reduced when using so-called power entry modules.
High-quality devices and machines are usually equipped with power entry plugs according to IEC 60320 on the power input side for AC current. Due to a separately required power cable with a coupling element and plug for the installation socket, this solution, in contrast to products with permanently installed power cables, is more expensive, but offers numerous advantages.
And what is more: Less individual parts increases overall reliability and usually provides additional space. E-T-A’s power entry modules combine up to 5 functions in a single component: a C14/C20 appliance inlet, resettable overcurrent protection, an ON/OFF switch, a line filter and add-on modules for undervoltage release, remote trip or auxiliary contacts. Unlike conventional standard modules with fuses, E-T-A’s power entry modules are fitted with a conveniently resettable circuit breaker.
This eliminates the need to replace blown fuses in the event of a failure and reduces equipment and machinery downtime. Thanks to screw mounting, the modules tightly fit in equipment and machinery and withstand even extreme pull-out forces of power cables.
