POWER ENTRY MODULES WITH INTEGRAL CIRCUIT BREAKERS | E-T-A

E-T-A expands its product portfolio with five new power entry modules and thus covers all requirements for overcurrent protection in modern device design.

These power entry modules are available in several variants:

• With integral resettable circuit breakers
• With integral circuit breakers/switch combination
• With circuit breakers and line filters

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.

XR38 Power Entry 5-in-1 Module

The number of individual components can also be reduced on the power input side. The solution here are power entry modules with integral resettable circuit breakers, i.e. purely resettable circuit breakers without on/off function. An example of this is the brand new XR38 E-T-A series.

E-T-A’s XR38 series power entry module combines a C14 inlet plug and a single or double pole resettable circuit breaker in a single component. The module thus replaces the IEC inlet plugs, fuses and fuse holders, that would otherwise have to be installed individually. In the case of a two-pole protection, this means replacing five components. Unlike fuses, the circuit breakers used here can also be easily, safely and conveniently switched on again after an overcurrent trip. Just one »click« is enough.
