A High-capacity, High-dielectric-strength,
Multi-pole Relay Used Like a Contactor
• Miniature hinge for maximum switching power for motor loads
as well as resistive and inductive loads.
• No contact chattering for momentary voltage drops up to 50%
of rated voltage.
• Withstanding more than 4 kV between contacts that are differ-
ent in polarity and between the coil and contacts.
• Flame-resistant materials (UL94V-0-qualifying) used for all in-
sulation material.
• Standard models approved by UL and CSA.

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. (The values given for AC rated current apply at 50 Hz or 60 Hz.)
2.
Performance characteristic data are measured at a coil temperature of 23°C.
3.
The maximum voltage is one that is applicable to the Relay coil at 23°C.

Note: 1.
The above values are all initial values.
2.
The contact resistance was measured with 1 A at 5 VDC using the voltage drop method.
3.
The operate and the release times were measured with the rated voltage imposed with any contact bounce ignored at an ambient tem-
perature of 23°C.
4.
The insulation resistance was measured with a 500-VDC megger applied to the same places as those used for checking the dielectric
strength.
5.
The electrical endurance was measured at an ambient temperature of 23°C.
6.
This value was measured at a switching frequency of 60 operations per minute.
