1. General

1.1 Selection

Technical data of the network at the point considered:the earthing systems (TNS,TNC),short-circuit current at the circuit-breaker installation point,which must always be less than the breaking capacity of this device,Network normal voltage.

1.2 Approvals and certificates

Detailed information, please refer to Certificates Table on the last page.

DZ47-125 Moulded Case Circuit Breaker

2. Technica data

2.3 Temperature derating

The maximum permissible current in a circuit breaker depends on the ambient temperature where the circuit breaker is placed. Ambient temperature is the temperature inside the enclosure or switchboard in which the circuit breakers are installed. The reference temperature is 30℃
