- Gantry Crane 3-Phase Voltage Monitoring: Protects crane motors against single-phasing, under voltage, and voltage imbalance. The relay allows phase reversal for crane operation and includes an adjustable time delay to prevent nuisance tripping.
- 3-Phase Motor Current Monitoring: Monitors current in one phase to protect against undercurrent and overcurrent conditions.
- Distribution Board Circuit Protection: Utilizes an Earth Leakage Relay (ELR) for full protection, set to trip at 300mA or higher to prevent fire and other faults.
- Escalator 3-Phase Motor Protection: Prevents escalator direction reversal using a 3-phase voltage monitoring relay, which also monitors under and over voltage conditions.
- 3-Phase Voltage Monitoring (LXPRC/S): Protects against phase loss, reversal, and voltage deviations. Offers user-adjustable settings and is suitable for global applications.
- Earth Leakage Protection (ELRM44V-30): Provides selectable trip levels and time delays, suitable for single and three-phase supplies, and compliant with IEC 60755.
- Circular and Rectangular Toroids (BZCT & BZCTR): Available in various sizes, compatible with all Broyce Earth Leakage Relays, and require no setup.
- Delay On Operate (LEDO & LEDO/2): Offers supply-initiated timing functions with selectable time ranges and multi-voltage supply.
- Customised Solutions: Broyce Control offers bespoke solutions tailored to specific application requirements.
- Monitoring Relays: Protect circuits from faults with under or over voltage and current sensing capabilities.
- Phase Presence Indicator: Provides visual indication of a 3-phase supply and detects faults like missing or reversed phases.
- Surge Protection: Protects circuits against voltage spikes and transients.

APPLICATION NOTES ^MONITOR CONTROL Distribution board circuit protection Full protection of an electrical distribution board is possible using an Earth Leakage Relay. As the ELR is monitoring the main incoming supply, the toroid /zero current transformer is sized according to the amperage of the supply i.e. 250A, 400A, etc. In this example, the Earth Leakage Relay would be typically set to a trip setting of 300mA or higher to protect mainly against fire and other faults Gantry crane 3-phase voltage monitoring and protection Protecting the crane motor against single-phasing (phase loss/blown fuse),...
