Contactor Auxiliary Contact Blocks
RSP Supply offers a complete selection of contactor auxiliary contact blocks designed to expand the functionality of motor control and power switching systems. These accessories are used with contactors, relays, and circuit breakers to provide additional control, signaling, and timing capabilities. Available options include standard auxiliary contact blocks, pneumatic time delay attachments, and short circuit contacts from trusted manufacturers such as Eaton, ABB, and Schneider Electric.
Auxiliary contact blocks are mechanically linked to the main contacts of a contactor and operate simultaneously when the contactor coil is energized or de-energized. While they do not carry the same current as the main power contacts, they play a critical role in control circuits by providing status indication, interlocking, and sequencing functions. Auxiliary contacts are available in normally open (NO), normally closed (NC), or changeover configurations to suit a wide range of control logic requirements.
Pneumatic time delay attachments add controlled timing functions to contactor operation, allowing delayed opening or closing of auxiliary contacts without electronic components. Short circuit contacts are used for specific control and protection applications where reliable auxiliary signaling is required. Together, these accessories help improve system coordination, enable remote monitoring, and support safe, efficient motor control in industrial automation environments.
FAQs
Q: What is a contactor auxiliary contact block used for?
Auxiliary contact blocks provide additional control or signaling functions, such as status indication, interlocking, or control logic, without carrying the main load current.
Q: What is the difference between a contactor and a relay?
Contactors are designed for higher current applications such as motor control, while relays are typically used for lower current control circuits.
Q: What types of auxiliary contacts are available?
Auxiliary contacts are available in normally open (NO), normally closed (NC), and changeover configurations.
Q: What is a pneumatic time delay attachment?
A pneumatic time delay attachment introduces a mechanical delay in the opening or closing of auxiliary contacts, allowing timed control without electronic circuitry.
Q: Which brands of auxiliary contact blocks are available?
RSP Supply carries auxiliary contact blocks and accessories from manufacturers including Eaton, ABB, and Schneider Electric.
