Coil rating for electromagnetic reset function

Nominal voltage
(Max. 10 sec)		 Drop-out voltage
(at 20°C)		 Nominal operating current
[±10%] (at 20°C)		 Coil resistance
[±10%] (at 20°C)		 Maximum voltage
(Max. 1 s)
5 V DC Min. 0.5 V
Max. 4.5 V		 725 mA 6.9 Ω 5.5 V
12 V DC Min. 1.2 V
Max. 10.8 V		 300 mA 40 Ω 13.2 V
24 V DC Min. 2.4 V
Max. 21.6 V		 150 mA 160 Ω 26.4 V
*
Notes: 1. If the rated voltage is applied to the coil for more than ten seconds or the maximum voltage is applied for more than one second, coil performance will deteriorate.
  2. Please apply more than 90% of coil voltage to reset the switch.
