FAQ

Features include a compact size with quick make-and-break mechanism, enclosed housing to prevent dust ingress, high electrical/mechanical life, and load & line reversibility.

Yes — they’re used in residential, commercial, and industrial applications, particularly in backup power systems requiring controlled switching.

Look for IEC compliance, a documented amperage range, pole configuration (3P/4P) options, and features like enclosed housing and reversible termination.

Offload switches suit applications where a brief power interruption during switching is acceptable, and are often a simpler, more cost-effective choice than onload switches for such setups.

It’s a switch that transfers power supply between two sources — but only after the load is disconnected — helping prevent electrical damage during the switching process.

Offload switches are suitable where a brief interruption during switching is acceptable, such as smaller backup systems, residential buildings, or low-load industrial areas — rather than critical, always-on operations.

It allows flexible wiring configurations in the panel — letting supply and load connections be reversed as needed without requiring a differently configured unit.

It’s based on the maximum current the connected load will draw, typically determined through a load calculation to avoid undersizing the switch for peak demand.

Frequentyl Asked Question

Eurogrid Electricals is a manufacturer, positioned as a trusted MCB Changeover Manufacturer in India rather than a reseller. 

Eurogrid's MCB changeover switches are built to IEC 60947-3, the international standard for low-voltage switchgear and switching devices. 

Check for compliance with relevant IEC standards, a documented product range across amperage ratings, and manufacturing (not just trading) credentials. 

Key features to look for include compact design, double-break contacts for safer isolation, DIN rail mounting for easy panel integration, and energy-efficient operation. 

 It transfers electrical load from the main power source to a backup source (like a generator) during an outage, ensuring uninterrupted power supply.

A manual changeover requires someone to physically switch the source, while an automatic transfer switch (ATS) detects a power failure and switches sources without human intervention.

It depends on the electrical system: 2-pole (2P) suits single-phase setups, while 4-pole (4P) is used for three-phase systems where neutral switching is also required. 

Yes — MCB changeover switches are specifically designed to transfer load between mains and a backup source like a generator during outages.

It's based on the connected load's current draw and the cable's current-carrying capacity — the MCB rating should protect the cable, not just the appliance, typically matched via a load calculation rather than guesswork.
