MORA Change Over Relay 120A Automatic/Manual Single Phase Power Switch

If you’ve ever lost power mid-task because your generator kicked in a few seconds too late or too early, tripping something in the process you know why a good change over relay matters. The MORA Change Over Relay 120A (model AES-988-2Z) is built to solve exactly that problem for homes, shops, and small industrial setups across Pakistan.

This is a single-phase, 220VAC relay rated for 120A, which puts it comfortably in heavy-duty territory enough to handle a full household circuit, a generator changeover, or a solar/inverter backup setup without breaking a sweat. What sets it apart from the cheaper no-name options flooding the market is the build quality: thick copper contacts and windings instead of thin aluminum, which means less heat buildup, less arcing over time, and a longer working life under real Pakistani load conditions frequent WAPDA cuts, voltage swings, and all.

The relay supports both automatic and manual operation, so you’re not locked into one mode. Set it to auto and it switches seamlessly between your main supply and backup power the moment one drops out no manual flipping needed. Or run it manually if that fits your setup better. It’s a 2-pole design, so it’s straightforward to wire into an existing panel without needing an electrician to redesign anything.

Typical places this MORA change over relay earns its keep: homes running backup generators during load shedding, small shops and retail counters that can’t afford downtime, solar/inverter installations that need clean switching between grid and stored power, and light industrial panels where a dropped connection means a dropped process.

It carries CE certification and comes from MORA Electric, a brand that’s built a track record in Pakistan’s electrical market for relays, protectors, and changeover equipment that installers actually trust. If you’re setting up backup power and don’t want to gamble on an unbranded relay burning out in six months, this is the safer bet and HN Electric ships it fast, with the specs to back up every claim on this page.
