Earth Leakage Relays N22 ELR C:0.4A-8.0A

Product Description

PROTIME's N22-ELR senses the Earth leakage current through CBCT. These leakage current if continues, can cause insulation breakdown resulting Earth fault, which results in to loss of life or damage to equipment. PROTIME N22-ELR energises / denergises an internal relay based on Mode of operation selected by user (i.e. Normal or Fail Safe) when Leakage current goes out of the range selected on the dial. PROTIME-Earth Leakage Relays are provided with user selectable two Tripping Ranges, and also two Time delay ranges in one unit. The CBCT is connected externally with the Busbar or cable carrying load current passed through it.

Versatile Voltage Range

The N22 ELR is engineered to function seamlessly within a voltage range of 90-270V AC/DC. This flexibility facilitates integration across a variety of environments, ensuring consistent performance regardless of your site's unique power supply characteristics.


Compact and Lightweight Design

At a mere 100 grams and measuring just 22.5mm in width, the relay is ideal for space-constrained panels. Its streamlined size enables straightforward installation in existing or new setups, maximizing operational efficiency without compromising on safety.


Protection You Can Rely On

With a ground fault current sensitivity adjustable from 0.4A to 8.0A, the relay helps safeguard personnel, equipment, and infrastructure. Backed by a 1-year warranty, it provides assurance of lasting protection and reliable after-sales support from a trusted Indian manufacturer.
