Note:1. The models in this table are UL/CSA certified. This is indicated with a certification mark on the products. (Except
crossbar bifurcated models MY4Z-CBG and MY4ZN-CBG)
2. The standard models with plug-in terminals, models with built-in diodes for coil surge absorption, and models with
built-in CR circuits for coil surge absorption were used in combination with the PYF[]A-E, PYF[]-S and PYF-[]-PU for
the EC Declaration of Conformity. These products display the CE Marking.

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 and inductance values are reference values only (at 60 Hz).
3. Operating characteristics were measured at a coil temperature of 23°C.
4. The maximum voltage capacity was measured at an ambient temperature of 23°C.
*1.There is variation between products, but actual values are 80% maximum.
To ensure operation, apply at least 80% of the rated value (at a coil temperature of 23°C).
*2.There is variation between products, but actual values are 30% minimum for AC and 10% minimum for DC.
To ensure release, use a value that is lower than the specified value.
