FF OM-611 current transformer power consumption limiter for use with current transformer

FF OM-611 is a power consumption limiter designed to work together with a current transformer to monitor and control electrical load. The device receives input from a connected current transformer, evaluates current levels in real time, and enforces power limits according to configured thresholds. It is intended for installation in industrial and commercial electrical panels where current-based power control is required to prevent overloads and ensure compliance with contracted power limits.

Advantages

The OM-611 provides continuous current monitoring and automated limiting of power draw without the need for direct measurement of voltage, simplifying integration when used with a current transformer. Its operation reduces the risk of tripping main protection and avoids penalties or extra costs associated with exceeding contracted power. The device is suitable for retrofitting into existing switchboards and offers a straightforward functional approach to maintaining stable consumption profiles.

Suitable for

• Industrial and commercial distribution panels requiring current-based power control
• Installations protected by a current transformer where overload prevention is necessary
• Sites with contracted power limits to avoid excess demand charges
• Retrofit projects where non-invasive current sensing is preferred

Key specifications

• Type: Power consumption limiter compatible with external current transformer input
• Function: Monitors current and limits load based on configurable thresholds
• Installation: Designed for mounting in electrical panels and switchboards
• Inputs: Requires connection to a current transformer for current sensing
• Control behavior: Automatic load limitation to prevent overload and exceedance of set power

How to use

Mount the OM-611 in the electrical panel according to standard installation practices and connect the secondary of a compatible current transformer to the device inputs. Configure the limiter thresholds and control parameters following the manufacturer's installation guide to match the site's contracted power and protection requirements. After configuration, the unit continuously monitors incoming current from the transformer and activates load limiting when measurements approach or exceed the set limits.

Usage recommendations

Use a correctly rated current transformer with proper secondary burden and ensure connections comply with local electrical codes. Verify settings during commissioning and periodically review thresholds to reflect changes in contracted power or load profile. For safe operation, perform installation and adjustments by qualified personnel familiar with panel wiring and protective device coordination.
