Protection Relays

Radix Protection Relays are intelligent Voltage Monitoring Relays designed to protect electrical equipment from abnormal supply conditions. Suitable for industrial and commercial applications, these relays help safeguard motors, generators, transformers, pumps, compressors, HVAC systems, switchgear and control panels, improving system reliability while reducing downtime and maintenance costs.

The relay continuously monitors the incoming supply voltage and frequency, comparing them with user-defined or factory-set operating limits. Whenever an abnormal condition is detected, the relay changes its output state after the configured delay, disconnecting or preventing operation of the protected equipment. Once the supply returns within the permissible limits, the relay automatically restores operation after the programmed power-on delay, ensuring reliable protection without nuisance tripping.

Key Features

1. Continuous monitoring of electrical supply conditions.
