Why Choose the ABB ELR96PD Residual Current Monitor?
The ABB ELR96PD is an electronic residual current monitor and relay designed for earth leakage monitoring and protection in low-voltage AC distribution systems. As part of the ABB ELR residual current relay series, it operates with an external toroidal transformer to detect residual currents and can be combined with suitable circuit breakers and tripping devices to provide effective earth fault protection.
The ELR96PD features a digital display for instantaneous indication of earth leakage current, giving operators clear visibility of system conditions directly from the front panel. Adjustable residual current sensitivity and intervention time allow the relay to be configured for a wide range of industrial and commercial electrical installations, while alarm and fault indication provide straightforward status monitoring.
With adjustable residual current sensitivity from 0.03–30 A, intervention times from 0–5 seconds and supply voltage options of 110, 230 and 400 V AC, the ELR96PD provides flexible protection for low-voltage distribution networks. Its 96 × 96 mm front-panel format is designed for integration into switchboards and electrical control panels.

Reliable Earth Leakage Monitoring and Protection
Residual current relays monitor the difference between currents flowing through conductors by means of an external toroidal transformer. When detected leakage exceeds the configured threshold, the relay can operate its output contact so that associated protection equipment disconnects the affected circuit.
The ABB ELR96PD combines adjustable protection settings with a digital leakage-current display, allowing operators to monitor residual current conditions as well as respond to earth faults. When coordinated with suitable MCBs, MCCBs, shunt trips and ABB toroidal transformers, it provides a flexible solution for residual current protection in low-voltage distribution systems.
Typical Applications
- Low-voltage electrical distribution systems.
- Industrial switchboards and distribution panels.
- Commercial electrical installations.
- Machinery and industrial control panels.
- Earth leakage monitoring and fault protection systems.
- MCB and MCCB protection arrangements using external shunt trips.
- Electrical systems requiring adjustable residual current protection.
