CNC 2P AC MCB Circuit Breaker YCB7-63N

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.
