In order to make it clear that it is not used for switching loads but rather has an activation/deactivation or control function, an auxiliary contactor is a regular (low-power) relay that is built like a “regular” contactor. It is used in conjunction with another contactor to connect/disconnect devices. Only switching currents up to 6 A are intended for use with auxiliary contactors.
An auxiliary contactor is a standard (low-power) relay that is constructed like a “power” contactor and is used in conjunction with another contactor. This is to make it clear that it doesn’t switch loads; rather, it has an activation/deactivation or control role. A circuit is connected or disconnected using an auxiliary contactor (i.e to control power contactors).
Auxiliary contactors typically have no primary contacts and only auxiliary contacts. In addition to major switching equipment like circuit breakers, relays, and contactors, auxiliary contacts are supplementary switching components. These contacts operate simultaneously with the primary switching mechanism since they are physically connected to it.
They are frequently utilised to indicate the primary device’s operational status and are frequently used as interlocks or retainers on the control circuit. Auxiliary contact sets are frequently included in contactors and circuit breakers as integral components or they may be modular snap-on devices that can be added or removed as needed.
They can have normally open, normally closed, or a combination of the two contact points. Secondary switching devices known as auxiliary contacts work in conjunction with primary switching apparatus.
Global auxiliary contactor market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
The 9…2650 A sizes of Rockwell Automation, Inc. Bulletin 100-E next generation contactors help to reduce width and weight while freeing up panel space. For contactors over 100 A, the universal electronic AC/DC coil allows direct connection to PLCs, significant energy savings, and considerably easier selection.
Orders can now be placed for ABB’s brand-new AFS contactors for safety applications. The introduction of the new contactors brings the company’s portfolio of safety components to a conclusion and makes it feasible to integrate ABB technology into every component of a plant’s safety architecture.
AFS contactors come with fixed front auxiliary contact blocks that simplify monitoring and regulating circuits for machine safety applications. Mirror connections and mechanically coupled contacts also contribute to system safety.
The ergonomic design of ABB makes use safer and easier. The recognisable yellow auxiliary contact block makes it quicker and simpler to detect the safety device in the panel during routine maintenance, saving significant time. A shielding sleeve helps stop unintentional manual operation.
