FAQ

What are the primary voltage taps on this transformer?

This transformer is designed for a primary voltage of 220V or 380V. It also includes a +15V tap, which is typically used for connecting to a 400V or 415V supply while maintaining the correct output voltage.

The included components provide overcurrent protection for the two 24V secondary circuits. This protects downstream control devices from damage in case of a short circuit or overload condition.

Yes, Legrand's OTFCE series are designed as control and safety isolating transformers. They provide galvanic isolation between the high-voltage primary circuit and the low-voltage secondary circuit, enhancing safety for operators and maintenance personnel.
