Switching PowerSwitching powerProduct of the switching current and switching voltage (in W for direct current, in VA for alternating cu rrent). Switching capacity (minimum) Due to slight corrosion of contacts, a minimum current / volt age is needed to allow fritting to keep the contact resistance low. Please note that in special contact metal combinations a thermal induced voltage of a few 100 micro V is possible. Maximum switching power Maximum permissible product of switching current and switching voltage (in W for d irect current, in VA for alternating current). Minimum switching power Product of the switching current and switching voltage that should not be undercut to ensure switching. |
