Why Choose the ABB LCR Load Management Relay?
The ABB LCR is a compact load management relay designed to monitor electrical power consumption and help prevent unwanted tripping of the main circuit-breaker. Installed downstream of the main protective device, it continuously compares actual system consumption with a user-defined maximum power threshold.
When consumption exceeds the preset limit, the LCR can disconnect a non-priority load, reducing demand before the main circuit-breaker operates. The device subsequently attempts to reconnect the disconnected load at configurable time intervals, providing automatic load management without requiring continuous user intervention.
Rated for a 230 V AC supply and 32 A monitored capacity, the ABB LCR provides an adjustable power threshold from 0.8 to 7 kW. A backlit LCD display, red LED and integrated buzzer provide clear operating information, while its compact 2-module DIN-rail format enables straightforward installation in electrical distribution boards.

Automatic Load Management to Reduce Unwanted Supply Interruptions
In installations where several electrical loads may operate simultaneously, total demand can exceed the capacity permitted by the main circuit-breaker. The ABB LCR monitors actual consumption against a preset limit and responds by disconnecting a designated non-priority load when that threshold is exceeded, helping maintain supply to higher-priority circuits.
Once demand has reduced, the LCR automatically attempts to reconnect the previously disconnected load according to the configured timing parameters. Adjustable thresholds and delays allow the load-management strategy to be tailored to the installation, while the LCD, LED and buzzer provide clear feedback on operating and load-disconnection conditions.
Typical Applications
- Residential electrical load management.
- Commercial building distribution boards.
- Demand control for non-priority electrical loads.
- Management of electric heating and other discretionary loads.
- Installations where simultaneous loads may exceed the main supply limit.
- Automatic prevention of unnecessary main circuit-breaker trips.
- DIN-rail electrical distribution and control assemblies.

Frequently Asked Questions
What does the ABB LCR load management relay do?
The ABB LCR monitors actual electrical power consumption against a preset maximum value. If the threshold is exceeded, it can disconnect a non-priority load to help prevent the main circuit-breaker from tripping.
What power threshold can be set on the ABB LCR?
The LCR provides an adjustable regulating threshold from 0.8 to 7 kW, with a setting resolution of 0.1 kW.
What electrical supply does the ABB LCR require?
The LCR is rated for a 230 V AC supply with a -15% / +10% voltage tolerance, operates at 50/60 Hz and has a rated monitored capacity of 32 A.
Does the ABB LCR automatically reconnect a disconnected load?
Yes. After disconnecting a non-priority load, the LCR can automatically attempt to reconnect it at preset intervals. Both the disconnection delay and reconnection interval can be configured from 0 to 9999 s.
How does the ABB LCR indicate that a load has been disconnected?
The LCR uses a red LED and integrated buzzer to indicate a load-off condition, while its backlit LCD provides clear operating information.
Trusted ABB Automatic Load Management
ABB LCR load management relays provide automatic demand control by monitoring electrical consumption, disconnecting non-priority loads when preset limits are exceeded and automatically attempting reconnection when capacity becomes available.
