Product Title

TOMZN TOB1-63H MTS 2P+2P 63A Dual-Power Manual Changeover Breaker

Short Description

The TOMZN TOB1-63H MTS 2P+2P 63A is a manual dual-power changeover assembly designed to select between two AC supply sources. It combines two 2-pole C63 MCB sections with a central mechanical interlock, 50/60Hz operation and a manufacturer-listed 6kA breaking capacity.

Long Description

The TOMZN TOB1-63H MTS 2P+2P 63A provides a manually operated method of changing a load between a normal AC source and a reserve supply such as a generator. The assembly shown uses two 2-pole TOB1-63H C63 miniature circuit breakers connected through a central mechanical MTS selector, helping prevent simultaneous manual engagement of both source sections.

TOMZN lists the TOB1-63H MTS family for two-path AC power systems operating at 50/60Hz, with a rated working-voltage range of 240–400V and available current ratings including 63A. The supplied 63A unit is face-marked 400V~, C63 and 6000A. The MCB sections carry IEC 60898-1 markings, while the central transfer mechanism is marked IEC/EN 60947-6-1.

This is a manual transfer device, not an ATS. Source changeover requires deliberate physical operation. Correct system design, source isolation, conductor sizing, protective coordination and installation must be completed by a qualified electrician in accordance with applicable local regulations.

Technical Specifications

Voltage Verification Note

The official 2P+2P MTS page describes a 240–400V AC family range and also contains a separate “230V” line. The supplied 63A unit itself is marked 400V~. Confirm the voltage requirement and exact SKU with TOMZN or the authorized supplier before installation.

Applications

• Utility-to-generator manual changeover systems.

• Normal-source to reserve-source selection.

• Residential backup-power distribution boards.

• Commercial backup-power panels.

• Small industrial or agricultural AC distribution systems where a 63A 2P+2P manual transfer arrangement is appropriate.

• Systems requiring manual rather than automatic source transfer.

Final suitability depends on system voltage, fault level, earthing arrangement, neutral-switching requirements and local electrical code.
