Earth Leakage Relays & Toroids

Shop earth leakage relays and toroids for sensitive earth fault detection on motor and general circuits. Trusted by industrial manufacturers Australia-wide.

N.A.W. Controls’ Earth Leakage Relays & Toroids detect leakage currents that could indicate insulation failure or dangerous fault conditions, tripping the circuit before damage, electric shock or fire risk occurs. The toroid (current transformer) senses leakage current, feeding a signal to the relay for tripping decisions.

Available in a range of sensitivities and toroid sizes, our earth leakage relay range suits industrial manufacturers and switchboard builders specifying sensitive earth fault protection for motors and general circuits.

Frequently Asked Questions

Earth leakage relays detect leakage currents that could indicate insulation failure or dangerous fault conditions. They trip the circuit before damage occurs, helping prevent electric shock, equipment failure and fire hazards.

The toroid is a current transformer that senses leakage current on the protected circuit, feeding a signal to the earth leakage relay to trigger tripping when a fault is detected.

Sensitivity (trip threshold) varies by model and application – our team can help you select an appropriate sensitivity for your circuit and risk profile.

Yes, earth leakage relays and toroids are used across a range of applications beyond motor protection, wherever sensitive earth fault detection is required.

Yes, our team can help match relay sensitivity and toroid size to your specific application.
