Haddan tashqari oqimdan himoyalangan qoldiq tok o'chirgichi (RCBO) asosan haddan tashqari oqimdan himoyalanish (haddan tashqari yuk va qisqa tutashuv) va tuproqli oqimdan himoyaga muhtoj bo'lgan ilovalarda qo'llaniladi.
Ular xodimlar va jihozlarning xavfsizligini ta'minlash uchun nosozliklar va sayohatlarni o'z vaqtida aniqlashlari mumkin. RCBO qisqa tutashuv, ortiqcha yuk, oqish va uch turdagi himoya funktsiyalari bilan eng funktsional hisoblanadi.
RCBO AC, A, B va AP-R kabi qoldiq oqimdan himoyalanishning barcha turlarini qo'llab-quvvatlaydi. Turar-joy va sanoat ilovalari uchun mos bo'lgan turli xil sindirish qobiliyatiga ega. TOBLE-80 RCBO ning 80A gacha bo'lgan nominal oqimi foydalanuvchi tomonidan belgilangan qutb raqamlarini qo'llab-quvvatlaydi. Ular bir fazali yoki uch fazali elektr tarmog'iga mos keladi. Uning nominal qoldiq oqimi 10 dan 500 mA gacha.
TOBNS-40 Type A RCBO 6KA 18mm 1P+N Frequency 50/60Hz Residual Current Circuit Breaker with Over Current and Leakage Protection
TOBD5-63 Type A Curve B RCBO 6KA 1P+N Electromagnetic Residual Current Circuit Breaker With Over Current and Leakage Protection
RCBO - bu tana xavfsizligini ta'minlash uchun ko'pincha umumiy uy tarqatish qutilariga o'rnatiladigan past kuchlanishli xavfsizlikni himoya qiluvchi elektr moslamasi.
Bu past kuchlanishli elektr tarmog'ida elektr bilan bevosita va bilvosita aloqa qilish uchun samarali himoya hisoblanadi. Himoya harakati oqimi chiziqning normal ishlashi paytida maksimal yuk oqimi bilan belgilanadi.
RCBO qoldiq oqim tizimini aks ettiradi, normal ish paytida tizim deyarli nol qoldiq oqimdir. Elektr oqishi va elektr toki urishi sodir bo'lgan taqdirda, kontaktlarning zanglashiga olib keladigan oqim qoldiqlari paydo bo'ladi, ammo bu oqim MCB va sug'urta o'chirilishi uchun etarli emas va qochqinning himoyasi ishonchli tarzda o'chadi.
RCBO kengligi odatda 18 mm, 36 mm (2P RCCB RCD bilan bir xil o'lcham) yoki kengroq (oqishdan himoya moduli MCBdan ajratilgan, ammo bizning TOBLE-72 kabi 80 mm kenglikdagi integratsiyalashgan turlari ham mavjud. mahsulotlar).
RCBO yuklarni himoya qilish uchun to'g'ridan-to'g'ri kontaktlarning zanglashiga olib kelishi mumkin va u oqish, qisqa tutashuv va ortiqcha yuk himoyasiga ega. Shuning uchun, terminal kalitlari uchun tizim yanada moslashuvchan va ixcham bo'lishi mumkin.
Bir fazali (1P, 2P) yoritish tizimlarida, uch fazali to'rt simli tarqatish (3P, 4P) liniyalarida yoki ishlaydigan neytral simni ishlatadigan uskunalarda qo'llaniladi, neytral sim RCBO'lardan o'tishi kerak.
Umuman olganda, RCBO ning tabiiy qutbi haddan tashqari yuk va qochqinlarni himoya qilish funktsiyalariga ega emas, faqat ulanish va o'chirish funktsiyasi mavjud, shuning uchun jonli simni neytral qutbga ulashga yo'l qo'yilmaydi, o'rnatayotganda mahsulot tavsifi va yorliq ma'lumotlariga e'tibor bering. ularni zanjirlarda.
The wiring should be carried out in accordance with the power and load markings on the RCBOs, and the two cannot be reversed, unless there is a special instruction that the RCBO can be reversed. (Some RCBOs can be reversed, such as the RCBO type (TOBNS, TOBD5).
Bir fazali va uch fazali yuklar aralashtirilgan uch fazali to'rt simli tizimda yoki uch fazali besh simli tizimda uch fazali yukni iloji boricha muvozanatlash kerak.

RCBOs are easy to install and can be retrofitted into existing electrical systems. Unlike separate RCDs and MCBs, which require additional wiring and installation, RCBOs can be installed in the same way as a traditional circuit breaker. This makes it easy to upgrade your electrical system to a safer and more efficient RCBO-based system.
RCBOs are compact and space-saving, making them ideal for installations with limited space. Unlike traditional RCDs and MCBs, which require separate devices for each function, the RCBO combines both functions into a single device. This means you can achieve the same level of protection in a smaller space, allowing for more efficient use of your electrical panel.
The combination of RCD and MCB functions in the RCBO provides superior protection against electrical hazards. The RCD function detects any imbalances in the electrical current caused by faults in the circuit, such as current leakage to the ground, while the MCB function provides protection against overcurrents caused by overload or short circuit conditions. This dual protection greatly enhances the safety of your electrical system.
While RCBOs may have a higher initial cost than separate RCD and MCB devices, they offer significant cost savings in the long run. Since RCBOs are a single device that combines both functions, you save on the cost of purchasing and installing separate devices. Additionally, since RCBOs provide superior protection against electrical hazards, they can help prevent costly damage to your electrical system and equipment.
The main difference between an RCD and an RCBO is that an RCBO includes the functionality of an MCB, while an RCD does not. This means that an RCBO can provide protection against both current imbalances and overcurrents, while an RCD can only provide protection against current imbalances.
Another key difference between the two devices is the way they are installed. RCDs are typically installed on distribution panels as the main residual current circuit breaker, providing protection for multiple circuits simultaneously. On the other hand, RCBOs are generally installed directly in the circuits they protect, safeguarding individual circuits, but they can detect faults more precisely and trip the circuit breaker.
The choice between an RCD and an RCBO will depend on the specific needs of your electrical system. If you are looking for a simple and cost-effective solution to protect against current imbalances, an RCD may be the right choice. However, if you need protection against both current imbalances and overcurrents, or if you have limited space in your distribution board, an RCBO may be the better option.
Replacing electrical components can be a daunting task, especially when it comes to ensuring the safety of your home or workplace. If you’re considering replacing an RCD (Residual Current Device) with an RCBO (Residual Current Circuit Breaker with Overcurrent Protection), there are a few factors to consider.
First, an RCBO can provide more comprehensive protection than an RCD, it’s not always necessary to replace an RCD with an RCBO. If you have a standard circuit breaker installed alongside the RCD, it may already be providing overcurrent protection. In this case, replacing the RCD with an RCBO may not provide any additional benefit.
However, if your electrical system doesn’t have a circuit breaker or if the circuit breaker is not providing adequate protection, replacing the RCD with an RCBO can be a good idea. An RCBO provides the benefits of both an RCD and a circuit breaker in a single device, saving space and providing more efficient protection.
It’s important to note that replacing an RCD with an RCBO requires a licensed electrician. They will need to ensure that the new device is compatible with your electrical system and install it correctly to ensure maximum safety.
