TOMZN 4P+4P MTS AC Dual Power Circuit Breaker MCB 50HZ/60HZ Change Over
TOMZN 4P+4P AC MTS Features
-
3‑Phase Dual Power Manual Transfer Switch (MTS) – Designed for three‑phase AC systems to manually switch between two independent power sources (e.g., grid and backup/generator), ensuring continuous power supply.
-
4P + 4P Pole Configuration – Each power source has a 4‑pole module (phases L1, L2, L3 + neutral), providing full control and protection across all conductors.
-
Integrated MCB Protection – Combines manual transfer switch functionality with a Miniature Circuit Breaker (MCB) to offer overload, short‑circuit, under‑voltage, and phase‑loss protection in one unit.
-
Manual Operation – User‑controlled changeover between main and backup power sources for reliable fail‑safe switching without automation.
-
Wide Voltage & Frequency Support – Suitable for 230 V / 400 V AC systems at 50 Hz / 60 Hz frequencies, compatible with a broad range of electrical networks.
-
Multiple Current Ratings – Available in common ratings such as 6 A, 10 A, 16 A, 20 A, 25 A, 32 A, 40 A, 50 A, 63 A to match different load requirements.
-
High Breaking Capacity – Typically around 6 kA, ensuring safe interruption of fault currents during protection events.
-
DIN‑Rail Mountable – Easy installation in electrical distribution boards and control panels using standard 35 mm DIN rail.

TOMZN 4P+4P MTS AC Dual Power Circuit Breaker MCB 50HZ/60HZ Change Over
The TOMZN 4P+4P AC Dual Power Manual Transfer Switch with Integrated MCB is a manual changeover device with built‑in circuit breaker protection designed for three‑phase AC dual power systems. It lets you manually switch between two independent power sources (such as the main grid and a backup generator) to maintain continuous and reliable power supply during outages or faults. The device supports 230 V–400 V AC at 50/60 Hz and features protective functions such as overload, under‑voltage, short‑circuit, and phase‑loss protection, making it suitable for critical applications where power interruptions are not acceptable, including factories, commercial installations, high‑rise buildings, hospitals, and emergency systems. Its dual 4‑pole design ensures complete switching of all three phase lines and neutral for safe and balanced power transfer.
