UniWave Electric
Our Miniature Circuit Breakers (MCB) and Molded Case Circuit Breakers (MCCB) are specifically designed to protect residential, commercial, and industrial electrical systems. These breakers automatically disconnect power in the event of an overload or short circuit, effectively preventing electrical fires and equipment damage.
MCBs are suitable for low current applications and offer rapid response protection, while MCCBs are designed for higher current requirements, making them suitable for larger electrical installations and equipment.
RIMM1HU series of molded case circuit breakers with rated voltages up to AC1000V and currents up to 400A. RIMM1HU series molded case circuit breakers have an interrupting capacity of up to 30kA at AC800V, enabling reliable system short circuit protection.
RIMM1HU series molded case circuit breakers comply with the following standards:

They are designed to protect residential, commercial, and industrial electrical systems by automatically disconnecting power in the event of an overload or short circuit, preventing electrical fires and equipment damage.
MCBs are suitable for low current applications and offer rapid response protection, while MCCBs are designed for higher current requirements, making them suitable for larger electrical installations and equipment.
They comply with EC 60947-1 / GB/T14048.1 (General Rules) and EC 60947-2 / GB/T14048.2 (Circuit Breakers) standards.
They operate in altitudes up to 2,000 meters. The environment should be non-explosive, without gases and conductive dust that could corrode metal or destroy insulation. Specialized TH (three-proof) customized versions are required for protection against damp air, salt fog, oil fog, and mold.
The RIMM1HU series is designed to handle up to 10,000 mechanical operations and 2,000 electrical operations.
The circuit breakers feature an IP20 degree of protection and can operate within an allowable ambient temperature range of -40°C to +70°C.
