SC65-63 high breaking miniature circuit breaker is a reliable electrical protection device designed for various power distribution applications. Our factory manufactures this MCB with advanced structure, high breaking capacity, and elegant appearance, ensuring stable performance in diverse environments.
Key Specifications & Parameters: The SC65-63 MCB is certified with CE, CB, ISO9001, and CCC, meeting international and national standards (IEC60898-1, GB10963.1). It operates at a rated voltage of 230/400VAC with a frequency of 50/60Hz, suitable for power systems with Ue 400V and below. The rated current ranges from 1A to 63A (1, 3, 6, 10, 16, 20, 25, 32, 40, 50, 63A), and it offers 1/2/3/4 poles optional to meet different circuit requirements.
The breaker features a mechanical life of 10,000 times (off - on) and is constructed with flame - retardant PA66 nylon material, ensuring durability and safety against fire hazards. Its protection degree is IP20, providing basic dust and finger protection. With overload and short circuit protection as standard, it also offers optional lighting or motor protection (C/D curve types) to match specific load needs.
Technical Performance: The SC65-63 has a breaking capacity of 10KA, ensuring effective interruption of fault currents. It endures temperatures up to 55°C (category 2 heat resistance) with a relative humidity of 95%, making it suitable for harsh environments. The arc - extinguishing medium is air, and it uses a manual operation type with normal speed, installed via DIN rail mounting for easy installation in distribution boards.
The current release character diagram (test current vs. rated current) defines its tripping behavior: for example, at 1.13In, it doesn’t trip (cool condition); at 1.45In, it trips within 1 hour (heat condition); and at 5In (C mode), it doesn’t trip if t ≥ 0.1s (cool condition), while at 10In (C mode), it trips within 0.1s. These characteristics ensure precise protection for connected equipment.
Applications: This miniature circuit breaker is ideal for office buildings, residences, and commercial spaces. It provides lighting and power distribution protection, as well as overload and short circuit protection for electrical equipment. Additionally, it can be used for infrequent power system transfers. Its compliance with IEC60898 and GB10963.1 standards ensures compatibility with global and domestic electrical systems.
Customization & Supply: Our factory offers wholesale, customized, and OEM services for the SC65-63 MCB. Whether you need specific current ratings, pole configurations, or branding, we can tailor the product to your requirements. The case material (PA66) and structural design (MCB) ensure reliability, while the available functions (conventional circuit breaker, overcurrent protection, OVP) make it a versatile choice for various electrical projects.
