Schneider Electric C16F4TM160D1 ComPacT NSX160 DC PV 4P 160 A 10 kA DC TM-DC Moulded Case Circuit Breaker

The C16F4TM160D1 is a 4-pole Schneider Electric ComPacT NSX160 DC PV moulded case circuit breaker rated 160 A at 40 °C, built for 1000 V DC photovoltaic circuits with a TM-DC thermal-magnetic trip unit and a DC breaking capacity (Icu) of 10 kA with all four poles connected in series, at a net weight of 2.8 kg.

Selection Notes

At 160 A the C16F4TM160D1 covers the higher end of string or combiner-box current in this DC PV frame, sharing the identical 140 x 161 x 86 mm body, 10 kA DC Icu and 1250 A fixed instantaneous pickup with the 125 A variant. The 0.7...1 x In adjustable thermal range lets the setting be dropped below 160 A if the array's actual short-circuit current is lower, without moving to the smaller-frame 125 A unit.

Applications

String or sub-array protection on 1000 V DC photovoltaic installations, ahead of the inverter DC input, where the breaker must clear DC fault current rather than only isolate it.
