The BFM136 multi-function energy meter's user-defined and easily configured alarm system enables users to take predictive maintenance action to avoid unnecessary outages.
The BFM136 multi fuction energy meter monitors up to 12 three phase circuits or 36 single phase circuits, or any combination of single or three phase circuits. This flexibility makes the BFM136 4 Wire Energy Meter perfect for multi-tenant facilities such as residential projects, office buildings and shopping malls.
This compact 120V energy meter is designed to easily fit into existing panel boards or be flush mounted nearby, thus eliminating the need for expensive retrofit projects or for allocating extra space for the device.
