Circuit breakers with error current protection (CBR) switch high currents, protect equipment, cables and lines from overcurrent and people from electric shock. DFL 8 are compact devices with integrated auxiliary switch and connection terminals for large line cross-sections. Type A switches are pulse and AC sensitive. This function is power independent. For switches of this variant, the error response current can be adjusted individually in steps to the respective application (0.3 A, 0.5 A, 1 A, 3 A). The limit non-response time can be adjusted accordingly. This makes it possible to implement a selective error-protection circuit in systems with staggered distributions. Devices in the standard design are designed for the monitoring of circuits with a measuring voltage of 400 V / 690 V and a measuring frequency of 50 Hz. Characteristics: adjustable measurement error current, measuring range from 100 A to 250 A, four-pole, measurement voltage 400 / 690 V AC, error current detection for alternating and pulsating DC current, function range of the error current output 0 - 690 V, function range of the error current control system 280 - 690 V, power and auxiliary power-independent output in the case of overcurrent and error current, high short-circuit power, connection terminals up to 185 mm2, threshold for inadvertent and delayed power-output control systems, can be used in the case of a low-voltage system, in the case of a low-voltage power system, in the case of the second power supply: The CBR type A does not provide comprehensive protection. For such applications we recommend our all-current sensitive CBR type B.
