Sanyu Electric AC 100V 200V Industrial Power Distribution Unit NV30-CA Breakers

Sanyu Electric AC 100V 200V Industrial Power Distribution Unit NV30-CA Breakers

This is a custom floor-standing industrial AC power distribution unit manufactured by Sanyu Electric Co., Ltd. (三友電気株式会社) of Japan, identified by the product label as Product No. 1050. The unit takes high-voltage AC input (via a multi-pin circular FROM MAIN connector) and distributes conditioned AC power at both 100V and 200V through separate labeled circular output connectors. An internal multi-tap transformer terminal board allows the primary winding voltage to be configured across a wide range of input voltages (taps visible from approximately 346V to 480V), making it suitable for use with varying mains supplies. Two analog panel voltmeters monitor output voltages continuously, and dual Mitsubishi NV30-CA molded-case circuit breakers provide overcurrent protection for each output circuit.

Applications

Custom industrial AC power distribution units of this type are used in manufacturing, laboratory, and industrial automation environments where equipment requires both 100V and 200V AC supplies from a single mains connection — particularly common in Japanese industrial settings where 100V and 200V are standard operating voltages. The multi-tap transformer allows the unit to be configured for different primary supply voltages (including 380V–480V three-phase industrial mains common in factories), making it flexible for use in varied facility environments. The Mitsubishi NV30-CA molded-case circuit breakers provide branch circuit overcurrent and earth-leakage protection. Units like this are typically used to power CNC machines, test equipment, precision instruments, or other apparatus with dual-voltage requirements — or to serve as a step-down/isolation distribution point for imported Japanese equipment operating on 100V in a 200V+ facility.
