Tests on GV2 motor protection circuit breakers (MPCB) are carried out in accordance with IEC 60947-4-1, usually inside its dedicated enclosure.
GV2 circuit breakers comply with this standard, and the temperature rise relative to ambient temperature under the conditions of the standard is as follows:
Manual commands: less than or equal to 25°K. Front panel: less than or equal to 40°K. Rear: less than or equal to 50°K


Note: As a general rule, all thermal magnetic circuit-breakers use electric heaters to deflect the bimetallic strips. It is therefore normal for a temperature rise to occur inside the product.
