Product details

What this 200 A MCCB does in the panel

Rated current holds at 200 A from 40 °C through 50 °C; it begins to derate above that — 194 A at 55 °C, 188 A at 60 °C, 182 A at 65 °C, 176 A at 70 °C. Breaking capacity drops as system voltage rises: 220 kA at 240 V, 154 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, 17 kA at 690 V.

Maximum power loss is 44.5 W, which factors into enclosure thermal calculations.

The SENTRON series carries the usual IEC/UL certifications for molded case circuit breakers; compliance documentation (RoHS, REACH) is available with the shipment.
