solid-statesingle-phasedigital

Product overview
TemBreak PRO series replaces the TemBreak2 range and provides molded-case circuit breakers (MCCB) and earth-leakage circuit breakers covering broad frame sizes. MCCBs are available from 30 A to 3200 A; earth-leakage circuit breakers from 30 A to 800 A.

Electronic types

• Standard electronic breakers with simplified protection setting options.
• Smart breakers with measurement display (current, voltage, power) and Modbus RTU network communication.

Features

• New products added in the 100 A to 630 A frames to extend the range.
• Reduced outline dimensions for Standard and Current-limiting series to optimize panel space.
• Smart breakers offer improved measurement accuracy and user convenience (display, configuration, communication).
