132 and 132AS are two similar products, both providing expanded safety and monitoring capabilities for different types of services. Both offer their own unique advantages and it can be difficult to determine which one is better for a specific application. Here is a look at the primary differences between the two products.

In terms of safety features, 132 offers expandable safety systems with tripping and disconnecting when needed. This includes over-voltage and short-circuit protection. The expandable nature of the system also makes it useful in applications such as monitoring and controlling downstream systems in addition to providing a critical form of protection. 132AS adds advanced safety systems including arc-fault detection, as well as features such as dual-channel roaming protection to prevent side-by-side faults on multiple devices. Additionally, 132AS has the ability to be integrated with existing systems to provide more comprehensive safety coverage.

In terms of monitoring capabilities, 132 offers basic monitoring capabilities with current, voltage and frequency readings. It can also provide output control so it can be used for remote monitoring and control. 132AS offers enhanced monitoring capabilities with the ability to measure peak current readings and extended-range frequency monitoring. It also provides superior data logging with more detail and flexibility. The system also includes the option of adding extended digital inputs and output and more data storage capacity.

Ultimately, both 132 and 132AS provide the safety and monitoring capabilities needed for many applications. However, 132AS offers expanded safety systems and monitoring options that can make it the better choice for more complex applications. For applications that require more sophisticated safety and monitoring capabilities, 132AS should be the option of choice.
