Siemens 3VA molded case circuit breakers come with a wide range of accessories that can be installed to enhance their functionality and performance. These accessories are designed to work seamlessly with the circuit breakers and can be easily installed to provide additional features and capabilities.
To determine which accessories are compatible with a particular Siemens 3VA circuit breaker, you can refer to the Circuit Breaker Compatibility Chart found below. The chart identifies the compatible locations and combinations in which various accessories can be installed within a Siemens 3VA molded case circuit breaker. While optional, these accessories can be used for alarming, remote indication, monitoring, and other features.
Some of the common accessories that can be installed within a Siemens 3VA molded case circuit breaker include:
Auxiliary Switches: These switches can be used to provide remote indication of the circuit breaker’s status or to control other devices.
Shunt Trips: Shunt trips are used to remotely trip the circuit breaker, typically in response to a signal from a protective relay or control system.
Under-Voltage Releases: Under-voltage releases are used to trip the circuit breaker when the voltage drops below a certain threshold, typically to prevent damage to equipment.
Motor Operators: Motor operators can be used to remotely open and close the circuit breaker, typically for applications where the circuit breaker is located in a hard-to-reach or hazardous location.
To install these accessories, you will need to follow the manufacturer’s instructions, which will typically involve removing the circuit breaker cover, connecting the accessory to the appropriate terminals or mounting points, and then reassembling the cover. You can also depend on AWC’s team of service professionals to do this job quickly and safely on site for you. The compatibility chart will help you to select the correct accessory for your specific circuit breaker and provide guidance on the installation process.
It’s worth noting that not all accessories are compatible with all circuit breakers, so it’s important to consult the circuit breaker compatibility chart before attempting to install an accessory. Additionally, some accessories may require additional wiring or modifications to the circuit breaker, so it’s important to follow the manufacturer’s instructions carefully and to ensure that the installation is performed by a qualified AWC professional.
