TOMZN 4P AC MCB C type 230/400V~ 50/60Hz Mini Circuit Breaker-TOB1-63H

TOMZN 3P+3P AC MTS Features

• 3P + 3P Dual Power Manual Transfer Switch (MTS) – Lets you manually switch between two three-phase AC power sources (e.g., grid and generator/backup), ensuring continuous supply when one source fails.

• Integrated Circuit Breaker (MCB) Protection – Combines transfer switch functionality with overload, short-circuit, under-voltage, and phase-loss protection in one unit for safer operation.

• Three-Phase Compatibility (3P + 3P) – Designed for balanced switching of all three phases between two input sources, suitable for industrial, commercial, and large-load three-phase systems.

• Wide Voltage & Frequency Support – Compatible with 230 V / 400 V AC and works on both 50 Hz and 60 Hz networks.

• Manual Operation – User-controlled changeover without automation, giving direct control over which source is supplying power.

• Wide Current Range – Available in various current ratings (e.g., 6 A up to 63 A), allowing selection based on load requirements.

• High Breaking Capacity (~6 kA) – Built to safely interrupt fault currents and protect the circuit during overloads and short-circuit events.

• DIN-Rail Mountable Design – Easy installation in electrical panels and distribution boards with standard DIN-rail mounting.
