100A High-Capacity Load Handling: Engineered to manage up to 100 Amps of current, making it suitable for large residential homes, commercial offices, and industrial workshops with heavy appliance loads.
Complete 4-Pole Isolation: Simultaneously switches all three phases and the Neutral line, ensuring total electrical separation between power sources and preventing stray currents or earth leakage trips.
Ultra-Fast Transfer Speed: Features rapid switching (often <50ms to <2s depending on model), ensuring minimal downtime for critical equipment like servers, medical devices, and security systems.
Dual Operation Modes: Offers the flexibility of Automatic Switching for hands-free power restoration and a Manual Override handle for testing, maintenance, or emergency backup control.
Intelligent Mains Priority: Automatically senses when city power (KPLC/Mains) returns and seamlessly transfers the load back from the generator or solar inverter to the primary grid.
Generator Auto-Start Signal: Includes a built-in dry contact/signal interface to automatically trigger your standby generator to start during a blackout and shut down once power is restored.
Enhanced Safety Interlocking: Equipped with both mechanical and electrical interlocking mechanisms to prevent the primary and backup power sources from connecting at the same time, protecting against back-feeding.
Compact DIN Rail Mounting: Designed for easy integration into standard distribution boards and consumer units using a space-saving 35mm DIN rail mount or plate-fix system.
Silver-Alloy Contact Points: Utilizes high-conductivity silver-alloy contacts to reduce electrical resistance, minimize heat buildup, and extend the mechanical life of the switch.
Real-Time Status Indicators: Features clear LED or mechanical visual indicators to show the current power source (Main vs. Reserve) and system health at a glance
Never stay in the dark again with the 100A 4-Pole Automatic Changeover Switch (ATS). This industrial-grade power management device is the ultimate solution for homes, offices, and businesses that require an uninterrupted power supply. In the event of a Kenya Power (mains) failure, this ATS intelligently detects the loss of voltage and automatically switches your entire electrical load to your backup source—be it a standby generator or a solar inverter—within milliseconds.
The 100A capacity makes it a robust “heavy-hitter,” capable of handling significant loads including multiple air conditioners, water pumps, commercial refrigerators, and extensive lighting systems.
While 2-pole switches are common for small setups, the 4-Pole design is the gold standard for safety and system integrity:
Total Neutral Isolation: By switching all four lines (L1, L2, L3 + Neutral), it ensures that the Neutral from the mains is completely isolated from the backup Neutral. This prevents “stray currents” and earth leakage trips.
Three-Phase Compatibility: Though it can be used for single-phase, the 4-pole design is natively built for Three-Phase (3-Phase) systems, allowing for balanced power distribution across your property.
Safety First: It provides a physical air gap between the two power sources, making it physically impossible for your generator to “back-feed” into the grid—protecting utility workers and your equipment.

Equipped with a versatile control toggle, the ATS allows you to choose between “Automatic” mode for hands-off protection or “Manual” mode. The manual handle is essential for maintenance or when you want to bypass the automation during specific service intervals.
Our 100A ATS is designed for speed. The transition happens so quickly (typically under 50ms) that most sensitive electronics, like desktop computers and Wi-Fi routers, won’t even reboot. It provides a “near-UPS” experience for your entire building.
To handle a massive 100A load without melting or sticking, the internal contacts are made from high-conductivity silver-nickel alloy. This ensures low contact resistance, minimal heat buildup, and an exceptionally long service life even with frequent switching.
The ATS is programmed with Utility Priority. Once the mains power returns and stabilizes, the switch will automatically transfer the load back to the grid and disconnect the backup source, allowing you to shut down your generator and save on fuel costs.
