DC Breaker Temperature Correction Factor

When selecting DC MCB (DC Miniature Circuit Breakers) for solar systems and other electrical installations, it is vital to consider the ambient temperature correction factor to ensure optimal performance and safety.

With corrected values catered to current ratings from 63A to 125A, our DC Breakers are made to run consistently across a large temperature range.

Breaker Current Capacity Changes

The rated current capacity changes with the increasing ambient temperature to minimize tripping failures or overheating. At 60°C, for instance, a 63A breaker will transport just 53.4A whereas a 125A breaker will carry 105.4A.

In high-temperature settings including solar PV installations, battery energy storage systems, and industrial control panels, this temperature derating guarantees long-term protection and efficiency.

Use the given adjustment chart always to match your breaker with actual running conditions. Our breakers are a dependable solution for DC circuit protection since they follow IEC/EN criteria.
