TERASAKI TemBreak PRO & TemPower PRO Circuit Breakers - Swiss Market Launch at POWERTAGE 2026!

The TemBreak2 series of molded-case circuit breakers has been redesigned as a new product family in the TemBreak PRO format. These molded-case circuit breakers are available in a wide rated current range from 30A to 630A (fully molded MCCB) and TemPower PRO from 630A to 2000A (ACB Air Circuit Breaker types).

The electronic switches are available in the following two versions:

• Standard version with simple protection configuration
• Intelligent circuit breakers with display of measured values and network communication via the Modbus RTU communication protocol

Key Features:

• Range expansion with new individual products from 100A to 630A
• Dimensions of the standard and current-limiting series have been reduced.

Thanks to their compact design, more space can be saved in distribution boards:

Summary: Intelligent circuit breakers with high measurement accuracy and high operating comfort are available!

Market Launch POWERTAGE 2026: TERASAKI TemPower PRO ...2000A

Available standard classes include:
Type C (Icu = 42kA) | Type S (Icu = 50kA) | Type H (Icu = 66kA)

Developed with the same dimensions as the 630AF to 1600AF draw-out models, making it even more compact than previous products. Compared to the predecessor, weight and volume have been reduced by 49% and 48% respectively. The unit can be mounted in a cabinet compartment with a width, height, and depth of 400 mm.

The orientation of the rear terminals (horizontal or vertical) can be changed by the customer. Quick-connect terminals are used for the control circuit connections. The need to tighten screws with a screwdriver is eliminated, making connection work significantly faster.

Depending on the application, "Standard" and "Smart" versions of the overcurrent release (OCR) are available. In addition to protection functions, the device features a measurement function for capturing circuit data. When equipped with an optional communication module, various types of circuit data can be collected and managed via remote monitoring.

Measurement accuracy has been significantly improved compared to the previous model, meeting the international standard IEC 61557-12. This ensures high accuracy of:

• ±0.5% for current and voltage measurements
• ±1% for active power measurements

By connecting the TemView PRO remote display unit to the TemPower PRO via a special cable and mounting it on the switchboard panel, the measured values from the intelligent OCR meter can be checked directly at the panel.
