Product Identification

Important: This product is a manual changeover/isolating switch. It is not verified as an MCB, fuse, RCBO, surge protector or automatic transfer switch, and it should not be presented as providing overcurrent or short-circuit protection. Use correctly rated upstream protective devices and installation by a qualified electrician.

Product Title

TOMZN TO219G 63A 2-Pole Manual Changeover Switch – 400V AC I–0–II Dual Power Transfer

Short Description

The TOMZN TO219G is a 63A, 2-pole manual changeover switch for controlled selection between two AC power sources. Its linked I–0–II handle provides Source I, centre-off isolation and Source II positions for manual utility, generator, inverter or PV-source transfer applications.

Long Description

Manage two independent AC supplies through one compact manual switching device with the TOMZN TO219G. Rated at 63A and 400V AC, the 2-pole changeover switch uses a mechanically linked blue handle to select Source I, disconnect both source paths in the centre 0 position, or select Source II.

TOMZN's official product information describes the TO219G as a dual-power manual transfer switch for power-source changeover. The official connection description confirms that position I connects terminals 1–2 and 5–6, position II connects terminals 1–4 and 5–8, and the centre position disconnects both groups. This makes it suitable for professionally designed mains/generator, mains/inverter and other two-source AC systems where manual control is required.

The TO219G is a switching and isolation device—not an automatic transfer system and not a substitute for circuit protection. Selection, cable sizing, enclosure, protective devices and installation must be completed by a qualified electrician in accordance with the applicable electrical code.
