Arc barrier equipped model

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.

Fully sealed model

The fully sealed model is a relay in a gas-tight plastic enclosure and thus exhibits stable performance in an adverse atmosphere of harmful gas, moisture, or powdery dust.

Note: 1. The rated current and coil resistance are measured at a coil temperature of 23°C with tolerances of +15%, –20%
for AC rated current and ±15% for DC coil resistance.
2. The AC coil resistance values are for reference only.
3. Performance characteristics data are measured at a coil temperature of 23°C.
4. The rated current of the AC operating coil is half-wave rectified current and is measured with a DC ammeter.
5. The peak reverse-breakdown voltage of the built-in diode is 1,000V.
6. The set coil of the Relay rated at 6 VDC is of the 5-minute rating. However, when it is used by connecting a diode
is series, it can be of the continuous rating.
7. By connecting an external resistor to each of the set and reset coils as shown in the table below, the rated current
of the Relay can be increased.
8. The maximum voltage is one that is applicable instantaneously to the Relay coil at 23°C and not continuously.
