SAK-200-MS-M - Electric Load Shed Device / (1) 200A Relays / NEMA 3R

When a homeowner wants to add a new EV Charger (or any load up to 200A), to an existing main or sub-panel that is at max capacity, the SAK-200MS-M offers the customer a reliable and affordable solution, without having to pay thousands of dollars for a full panel upgrade.

Allows up to a single 200A load to be added to any main service panel or sub panel that is at risk of overload, or will become overloaded, when a new load is introduced. The onboard intelligent micro-controller monitors the load on the existing panel and only allows the added load access to the panel when capacity is available. Installation requires an open 200A breaker.

• Can be installed on any main or sub panel up to 400A to add managed loads up to 200A continuous.
• Adapts to any application using the precision field adjustable set points. These maximize access to the added load and prevent looping.
• Field adjustable set points include: panel overload amperage, overload inrush cutoff delay, restore amperage threshold, load restore delay time and line-loss compensation adjustment for CTs. Controller LCD displays actual real-time amperage on panel.
• Controller is self-powered from line voltage. External power supply not required. Can control 120 VAC single pole or 208–240VAC double pole circuits.
• Prevents overloading and saves costly upgrades to panel and/or electrical infrastructure.
• Utilizes a magnetic latching relay for long-term reliability, and box-lug in and out terminals for ease of installation.
• 2 year warranty
• Comes standard in NEMA 3R enclosure
