Revolutionize Your Energy Management

Introducing the Milesight CT303, a state-of-the-art LoRaWAN® Smart Current Transformer designed for precise, real-time monitoring of electrical consumption. Engineered for efficiency and accuracy, the CT303 is the ideal solution for smart building energy management, equipment performance monitoring, and predictive maintenance. Its innovative one-to-three design allows you to measure the electricity of up to three different objects simultaneously, providing comprehensive insights into your energy usage patterns to foster conservation and reduce operational costs.

Effortless Installation & Unmatched Performance

The CT303 features a user-friendly, non-invasive clamp-on design that ensures safe and rapid installation without the need to interrupt power or risk circuit damage. This cable-free deployment simplifies the process, reduces labor costs, and offers flexible placement. A standout feature is its self-powered technology; the device derives energy directly from the measured circuit, completely eliminating the need for batteries and ensuring continuous, seamless operation. With a high sampling frequency of up to 3.3kHz, the CT303 delivers superior accuracy (±1%), outperforming competitors and guaranteeing unparalleled detail in your energy data.

Smart Monitoring with Instant Alerts

Stay ahead of potential issues with intelligent threshold alerts. You can set minimum and maximum current thresholds and receive instant alarms when these are triggered. The over-current alert provides immediate notification when the current exceeds the rated limit, accompanied by a flashing LED indicator for quick visual confirmation. For enhanced safety, an optional external wire temperature sensor can be added to trigger alerts when a set temperature is reached. Leveraging the power of LoRaWAN® technology, the CT303 ensures stable, long-range wireless data transmission, making it perfect for multi-story commercial and industrial buildings.

Key Features:

  • Multi-Target Measurement: Unique one-to-three design monitors up to three circuits at once.
  • Self-Powered Operation: No batteries required; powered by the measured circuit for uninterrupted service.
  • Non-Invasive Installation: Clamp-on probe allows for quick and safe setup without power interruption.
  • Superior Accuracy: High sampling frequency up to 3.3kHz provides highly detailed and precise energy tracking.
  • Real-Time Alerts: Configurable thresholds for current and temperature provide instant notifications of irregularities.
  • LoRaWAN® Connectivity: Ensures reliable long-range, low-power wireless communication for seamless IoT integration.
  • Efficient Energy Tracking: Calculates accumulated ampere-hours in real-time at one-second intervals for precise consumption analysis.

Well made shoes.
Size: 11.5, Color: Black
Four stars because of the weight. Too heavy for my complete comfort. Also I have a narrow foot (C width) and these are too wide for me. Heavy socks make them wearable but not as comfortable as I would have liked.

Something's changed at Florsheim
Size: 11.5 Wide, Color: Black
I have a pair of size 11W Florsheim Palermo loafers that have lasted over 8 years and are still soft and exceptionally comfortable. Ordered a pair of 11W Florsheim Milano on Amazon but they are too small and have a cheap plastic sole. So, ordered 11.5W Florsheim Berkley and they were way too big. Returned them and ordered 11W Berkley instead and they were also too big ... and the Berkley also has a rubber sole instead of the original leather shown in the product photos. Guess they just don't make them like they used to.

Beware of the Brown Crazy Horse version.
NOTE: This review is COLOR SPECIFIC and concerns the Brown Crazy Horse version of this shoe. I am a loyal Florsheim customer having purchased Florsheim Imperials in years past. They are a fine shoe. However, I have to admit complete frustration with the Florsheim Berkley Flex Penny Loafer in "Brown Crazy Horse." The photos in the listing show a shoe with gloss...a shine. The photos on the box show a shoe with shine. Don't believe the photos. "Brown Crazy Horse" is, at best a dull matte finished leather. If you want a classic penny loafer with the classic Florsheim look this is NOT the color to choose. When the shoes arrived and the shoes did not match the photo on the box, I ignorantly assumed it was merely a case of the wrong shoes in the box so I exchanged them for another pair, which was a big mistake. It is Florsheim's incorrect photo and box label that caused me the inconvenience of going through two pair and then having to return both. I would assume other colors are as pictured in their listings because I cannot imagine that every Florsheim Berkley Flex Penny Loafer is a dull matte finish. I'm sorry that I do not have photos of the dull finished shoes. You'll have to take my word for it. They are a matte finish at best.

Just right, great quality and value (in the price)
Size: 11.5 X-Wide, Color: Burgundy
Exactly what I'd expect from a Florsheim. I'm delighted. Folks, let me share one mistake I made on my way to a good fitting pair of shoes. I ordered some in my size (I have a big foot, especially in width). I ordered what I thought I needed and it came in wide enough, but too short (the short was the surprise), but we all are told: "Manufacturers vary in their sizes not only from each other but from shoe model to shoe model." I want you to know I believe in that when it applies to clothes, especially children's and womens fashions in my life's experiences, but NOT with shoes, especially main-brand-deluxe. I ordered the next half-size up and now I have too large, how can that be? I found out when I pulled the paper stuffing out, in particular the LAST glob that extends from the middle to the toe, that it WASN'T the last glob, there was indeed a rather small glob still way down in the toe, almost pointless for this minor bit of stuffing being separate from the other, but it was. I had already innocently troubled Amazon with returns of shoes that would have fit, so I'll keep the half-size too large as a life lesson. I ordered this pair in the size I believed I was all along and viola, a good fit. What changed? When that last toe piece of paper wadding that's hard to see and even harder with a big hand to reach, the shoe fit perfectly. That's a lot of trouble because of a small piece of paper that was hard to see, but that's why I write this review for you so that you can make sure all the paper is really out when you already think it is. Amazon has been good enough not to hold me accountable and in return I'll not only repeat buy, I tell you of my experience.
