WebThe circuit protection market demand is changing based on the growth of 24V DC control voltage. In the US and Canada we’ve seen a shift from120V AC to 24V DC as the voltage of choice for control circuits. Generally, this change is driven by a trend to use this lower voltage as a safety precaution and to reduce personnel protection requirements.
