MK Relays
• Built-in mechanical indicator enables checking contact
operation.
• Two modes can be used to check circuits for models with
latching lever.
• Nameplate provided on models with latching lever.
• All materials are RoHS compliant.
• UL and IEC (TÜV) certification.

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.
Performance characteristic data are measured at a coil temperature of 23°C.
The maximum voltage is one that is applicable instantaneously to the Relay coil at 23°C and not continuously.
For DC-operated Relays with the LED indicator built-in, add an LED current of approx. 5 mA to the rated current.

When
using the PF083A and
