Springer Controls offers the CR460 series of lighting contactors from ABB. Your Lighting Contactor Guide Number of Poles Poles can be added to the base as single poles or double poles to create the desired total number of poles in the circuit. Each pole is rated for 30A for lighting applications. Poles can be converted… Read more »
Contactors are a kind of electrical switch used in the switching of electrical circuits. Commonly used in large motors, they’re useful for various purposes in industry, including protecting motors from overload conditions or overcurrent within the motor. To do their job correctly, the contactor’s power rating must be greater than that of the circuit to… Read more »
What is an Overload Relay? A thermal overload, sometimes called an overload relay, is an essential part of a motor starter. The contactor is there to act as the switch and transmit power to the motor. The overload is there to prevent damage to the motor if the motor starts drawing too much current, i.e.,… Read more »
Various manufacturing processes necessitate the control of temperatures for safety purposes and maintaining efficiency during production. In various industries, electronic temperature controllers help keep temperatures within certain parameters to prevent system failures that can increase repair costs and unplanned downtime. Temperature control is vital in many industrial processes to ensure products perform acceptably for their… Read more »
An electrical load’s distribution is known as its phase and can be described as a single-phase or 3-phase motor, depending on the number of supply phases. How each of these motors starts depends on different starting mechanisms, though all consist of a coiled startup winding, with certain motors featuring a capacitor. Understanding the differences between… Read more »
