Circuit Breakers from a Low-Voltage Factory
TOMZN has manufactured low-voltage protection devices since 2002. This category covers our full circuit breaker range: miniature circuit breakers (MCB) for final circuits, moulded case circuit breakers (MCCB) for main distribution, residual current circuit breakers (RCCB) for earth leakage protection, and combined RCBO units where space on the DIN rail is limited. Dedicated DC breakers for solar strings and battery systems are included in the same range.
Across the range you can specify pole configuration from 1P to 4P, single-phase and three-phase versions, AC and DC duty, and both standard and high breaking capacity variants. All models mount on standard 35mm DIN rail, so they drop into existing consumer units and distribution boards without redesign.
Products are CE and CB certified and currently ship to more than 50 countries. We support OEM and ODM work, including customer branding and packaging.
Tell us your rated current, pole count, breaking capacity and target market, and we will come back with the matching model and a quotation.
