Additional information

Features	Motor drive optional
Fitted with:	Switched-off indicator
Special features	Cassette must be separately ordered.\nIZMX-DTP-PTM external voltage measuring module required\nsuitable for zone selectivity\nsuitable for communication\nwith integrated system monitor\nwith integrated test possibility\nwith graphic LCD color display\noptionally fittable by user with comprehensive accessories\nThese are values used in separate switchgear. The actual values will depend on the temperature around the circuit-breaker, which is influenced by the ambient temperature, the degree of protection (IP), the mounting height, the partitions, and any external ventilation. Depending on the specific switchgear design, this may result in derating, which can then be compensated for by increasing the cross-sectional area. Temperature rise tests in the specific switchgear can provide specific and detailed information.
Suitable for	Main conducting paths with 57.6 kA in IT electrical power networks up to U = 440 V
