The arc barrier equipped model is a relay designed to prevent arc short-circuiting between phases and can be used in a circuit which has potential difference between phases. The switching power of such a circuit with potential differ­ence must be limited to less than 1/2 the rated load when using this Relay.
The built-in diode model is a relay which incorporates a diode for ab­sorption of the reverse voltage that may be generated when the coil is de-energized. Because the release time of this model is long­er than the standard model, pay adequate attention to this point in designing a circuit. Also, pay at­tention to the + polarity of the coil. The reverse-breakdown voltage of the diode is 1,000 V.
The built-in operation indicator model has a newly added opera­tion indicator to the conventional operation indication mechanism and facilitates operation monitor­ing without being affected by am­bient illumination. With the -N model (rated at 16, 12, 24, and 48 VDC) and -N1 model rated at 6, 12, 24, 48, and 100 VDC), pay attention to the + polarity of the coil.

Precautions
Refer to page 11 for general precautions. A DC coil model with a built-in indicator or built-in diode has coil
polarity. Be sure to wire the terminals correctly, otherwise the diode may be broken or the operating indicator may not be lit. Furthermore, as a result of the short-circuiting of the built-in diode, the devices in the circuit may be damaged.
