Distribution box busbar temperature
The IEC 61439-1 sets the thermal limit in busbars working at the maximum working load. Here, 140°C (which is 105K over the ambient temperature of 35°C) is the upper safe temperature limit. Here are the key technical parameters considered in sizing: Rated Current (Ir): Continuous current the busbar must carry without exceeding permissible temperature. The application of the guide is focused on the manufacturing of distribution boards up to 630 A and in addition to checklists and instructions regarding the verifi cation of compliance with the maximum temperature rise. With the aid of a correction factor (k2), the continuous currents specified in the follow-ing table may be adjusted to alternative oper-ating temperatures. For safe. Switchgear and busbars can be constantly and comprehensively monitored for temperature rises without a complicated setup.
