Due to improved conduction efficiency,
wide terminal blades are used. (for high
capacity type)
TYPICAL APPLICATIONS
RoHS compliant
• Photovoltaic power generation
systems (Solar inverter)
• Contact gap: 2.5 mm (VDE0126
compliant)
Compliant with European photovoltaic
standard VDE0126
Compliant with EN61810-1 2.5 kV surge
breakdown voltage (between contacts)
• Contributes to energy saving in
devices thanks to reduced coil hold
voltage
Coil hold voltage can be reduced down to
40% of the nominal coil voltage (ambient
temperature 20°C
68°F).
This equals to
operating power of approximately 310
mW.
*Coil hold voltage is the coil voltage after
100 ms following application of the
nominal coil voltage.

Notes: *1. This value can change due to the switching frequency, environmental conditions, and desired reliability level, therefore it is recommended to check this with the
actual load.
*2. Wave is standard shock voltage of
±1.2×50µs
according to JEC-212-1981
*3. Coil hold voltage is the coil voltage after 100 ms following application of the nominal coil voltage.
*4. The upper operation ambient temperature limit is the maximum temperature that can satisfy the coil temperature rise value. Refer to Usage, transport and storage
conditions in NOTES.
*5. Release time will lengthen if a diode, etc., is connected in parallel to the coil. Be sure to verify operation under actual conditions.
