描述:Connection circuit breakers series DB90 LV subscriber circuit breakers for power up to 36kVA. **Instantaneous differential models:** Protects people from indirect contact and equipment from isolation faults. **Selective differential models:** Ensures total selectivity with high sensitivity (30mA) differential devices installed downstream so that only the start with an isolation fault is turned off. Enables installation of a lightning arrester immediately upstream of the circuit breaker with out risk of untimely tripping of the latter. Enables service quality requirements to be taken into account by certain receivers (freezer, computer equipment etc.). Meets EDF requirements. Differential devices with test button. **Standard: NFC 62411** Sensitivity: | 500mA ---|--- ref.
