Low-voltage busbar operating temperature standard

Low-voltage busbar operating temperature standard

IEC 61439 establishes comprehensive design rules for low voltage switchgear assemblies up to 1000V AC or 1500V DC, mandating verification of temperature rise limits, short-circuit withstand strength, dielectric properties, and protection against electric shock through testing . IEC 61439 is a standard developed by the International Electrotechnical Commission (IEC) that covers design verification for low-voltage electrical products and assemblies. 7 cycles of 24 h each to salt mist test according to IEC 60068-2-11; (Test Ka: Salt mist), at a temperature of (35 ± 2) °C.

Low-voltage main busbar operating temperature

Low-voltage main busbar operating 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. The test shall be carried out according to IEC 60068-2-2 Test Bb, at a temperature of 70 °C, with natural air circulation, for a duration of 168 h (7 days) and with a recovery. The maximum temperature that low voltage copper busbars can sustain depends on several factors including the size and thickness of the busbars, the ambient temperature, and the current flowing through the busbars.
