FAQ

Eurogrid’s onload changeover range spans 63A to 1250A, available in Three Pole and Four Pole configurations, built to IEC 60947-3.

Features include a quick make-and-break mechanism, enclosed housing to prevent dust ingress, silver-plated current-carrying parts, and high electrical and mechanical life.

Manufacturers like Eurogrid Electricals offer onload changeover switches engineered for seamless power transfer, built to standards like IEC 60947-3.

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

Local manufacturing typically means faster lead times, easier after-sales support, and products designed around Indian power infrastructure conditions.

It’s a switch that transfers electrical load between two power sources, such as mains and a generator, without interrupting the load. It uses a quick make-and-break mechanism to maintain continuous supply.

An onload changeover switch can transfer sources while the circuit is live and under load, while an offload switch requires the load to be disconnected before switching.

It’s based on the maximum load current the connected system will draw. This is typically calculated during a load study rather than estimated, helping ensure the switch isn’t undersized for peak demand.

Yes. Reputable suppliers typically offer both Three Pole and Four Pole executions to match single-source and neutral-switching requirements.

Yes. They are used across factories, commercial buildings, and infrastructure projects where uninterrupted power management is required.

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.
