Delivery and Shipping

We ship the same day on all in stock orders that are placed prior to 4 p.m. EST, Monday through Friday. We offer Flat Rate shipping ($9.00 for UPS Ground) and expedited shipping can be selected at checkout.

In some instances simply replacing a Sirius 3RT contactor coil is all that is needed to get a contactor back up and running. Siemens offers replacement coils on all frames sizes from S0 to S12 and this can be the most cost efficient method for contactor maintenance. The magnetic coil is switched on and off directly with the control supply voltage via terminals A1/A2. In addition, the contactor coil voltage has a tolerance of 0.8 times the lower rated control supply voltage (Us min) and 1.1 times the upper rated control supply voltage (Us max), within which the contactor switches reliably and no thermal overloading occurs.
