CNC Electric 4+4 Pole Manual Transfer Switch (MTS) – Dual Source Grid & Generator Change-over

Ensure uninterrupted, safe power switching with the CNC Electric 4+4 Pole Manual Transfer Switch (MTS).

Designed for heavy-duty dual-source systems, this AC manual change-over switch provides seamless control over power transfer between two independent supplies (for example, the main utility grid and a generator or solar/inverter backup). Perfect for residential estates, commercial buildings or light industrial setups across Pakistan, this 4 P + 4 P (4-pole + 4-pole) configuration caters for three-phase four-wire systems and larger single-phase loads requiring full isolation.

Key Features & Benefits:

• 4P + 4P Configuration: Supports full four-pole switching of live, neutral and phases in a 3-phase or large single-phase dual-source system. Ideal for high-capacity loads, distributor boards or commercial setups requiring reliable Grid/Generator change-over.
• Manual Transfer Switch (MTS) Operation: Gives you direct manual control when switching between power sources — no automatic switching, so you decide when and how the changeover happens. Ideal for planned back-up power use and controlled transitions.
• Dual Power Changeover Capability: Built for safe and reliable change-over between utility supply and backup supply (generator, inverter, hybrid solar) — ensuring your critical loads remain powered when the main source fails.
• Safety Interlock & Isolation Mechanism: Mechanical interlock prevents both power sources from being connected simultaneously, eliminating risk of back-feeding or overloads. Compliance with dual-source safety rules.
• AC Dual-Source Compatibility & High Load Capacity: Engineered for AC 50 Hz/60 Hz systems typical in Pakistan, and suitable for commercial/residential switchgear environments.
• Robust Build & Panel-Friendly Design: Suitable for installation in main switch rooms, meter rooms, distribution boards, commercial panels or industrial power supply rooms. CNC Electric switchgear in Pakistan offers local support and reliable spares.

Applications:

• Large homes, apartments or housing complexes with grid + generator or solar backup.
• Commercial offices, shops, restaurants or malls requiring dual power feeds and safe manual change-over.
• Light industrial, manufacturing or infrastructure installations where manual but high-capacity changeover is needed.

Why Choose CNC Electric?
CNC Electric is a trusted name in Pakistan’s electrical switchgear market, offering quality transfer switches, change-over devices and manual/automatic transfer solutions. By selecting their 4+4 Pole MTS, you get both power-level capability and local support for maintenance, installation and spares.

Installation & Usage Tips:

• Ensure the switch is installed by a certified electrician and sized correctly for your load and backup source.
• Clearly label both input sources (e.g., "Grid In", "Generator In") so during power-outage you switch confidently.
• Before transferring, turn off non-critical loads if on smaller backup generator to avoid overload.
• Schedule periodic inspection of the switch & wiring—particularly in dusty/humid environments—to maintain safety and long service life.
