The NRAS3100-3 series from IDEC Corporation is a line of electromagnetic circuit breakers designed for 3-pole configurations, suitable for applications ranging from small commercial to residential settings. These breakers cater to current ratings from 3A to 30A, with a voltage rating of 250VAC. They are ideal for protecting electrical circuits from overcurrent conditions that could lead to fires or damage to connected equipment.

If you're working on projects involving multiple circuits, these breakers offer a compact and reliable solution. Their electromagnetic design provides fast response times, making them effective in tripping quickly when overloaded. One thing worth noting is their ease of installation; they come with clear labeling and are compatible with standard mounting panels, which streamlines integration into existing electrical systems.

Engineers tend to reach for this when they need a robust, space-efficient breaker for multi-wire branch circuits, especially in areas where high reliability is crucial. They also find these breakers useful in situations requiring precise control over circuit protection, such as in industrial automation systems or complex building electrical layouts.
