Eaton RCD circuit breaker

Symmetrical distribution of the ballasts on all phases is advantageous. The function of the switch is independent of the position.- The circuit breaker can therefore be used for "fault protection" and "additional protection" in accordance with the installation regulations.- The 4-pole switch can also be used with 2 or 3 poles. See connection examples.- The test button "T" must be actuated every year The system operator must be demonstrably informed about this circumstance and his responsibility. When used under special conditions (construction sites, laboratories), the test button may have to be pressed more often. Here, the statements of the respective installer regulations apply.- By pressing the test button "T", only the function of the residual current device (RCD) is tested. This test does not replace the earth resistance measurement (RE), nor the proper protective conductor status test, which must be carried out separately.- Type- -/B: Short-time delayed + surge-proof 3 kA, all-current sensitive, type B (ÖVE E 8601)- Type- -/B: High reliability against false tripping. Mandatory for circuits with possible personal injury or property damage in case of false tripping (ÖVE/ÖNORM E 8001-1 § 12.1.6).- Type- -S/B: Selective + impulse-proof 5 kA, all-current sensitive, type S/B- Type- -S/B: Selective residual current circuit breaker. Protects with all types with residual current forms.
