(0.15 MHz to 30 MHz): device class A (industry)<br />
1 ) IP20 only with attached box terminal (delivery state). Without box terminal IP00.<br />
2 ) Device class B (public power supply networks) is complied with only in the case of variants <strong>3RW3</strong>.-1AB0. with <strong>control</strong> supply voltage UC<br />
of 24 V. For the <strong>3RW3</strong>.-1A.1. variants with a <strong>control</strong> supply voltage UC of 110 V to 230 V, single-stage filters (e.g. type B84143-A...) must be<br />
connected upstream.<br />
