BLUEJAY ELR-4MA Earth Leakage Relay: Advanced Protection for Modern Electrical Systems

BLUEJAY’s ELR-4MA AC Earth Leakage Relay is a cutting-edge safety solution that safeguards industrial and commercial environments from electrical hazards. Integrating residual current transformers (RCTs) detects leakage currents with precision, triggering alarms or shutdowns to prevent equipment damage, downtime, and risks to personnel.

Tailored Protection for Every Application:

Type AC RCT: Ideal for traditional linear loads (e.g., heaters, ovens) with pure sinusoidal AC currents.

Type A RCT: Detects pulsating DC and AC leakage in electronic equipment (e.g., office devices, microwaves).

Type F RCT: Engineered for single-phase variable frequency systems (e.g., HVAC, pumps) with high-frequency currents up to 1kHz.

Type B RCT: The ultimate solution for complex environments (e.g., EV charging, solar inverters), handling AC/DC hybrids and multi-phase rectifiers.
