TOB7Z-63 | 2P DC 1000V Circuit Breaker: Ultimate Solar & DC Protection
Welcome to Ryksolar, your trusted source for high-voltage DC protection. The TOB7Z-63 | 2P DC 1000V Circuit Breaker is a premium miniature circuit breaker (MCB) engineered specifically for solar photovoltaic (PV) systems. While a standard AC circuit breaker is designed for the grid, this DC-rated model at Ryksol Energy is essential for protecting your solar strings, batteries, and inverters from high-voltage DC faults.
Why DC Protection is Critical for Solar
Direct Current (DC) arcs are much harder to extinguish than AC arcs. The TOB7Z-63 features a specialized magnetic arc-extinguishing chamber that safely breaks the circuit under load. Whether you are building a small off-grid setup or a large commercial PV plant, this miniature circuit breaker ensures your panels and cables stay safe from overcurrent damage.
-
1000V DC Rating: Specifically designed to handle the high-voltage strings of modern solar panels.
-
2-Pole Isolation: Simultaneously disconnects both Positive (+) and Negative (-) lines for total system isolation.
-
63 Ampere Capacity: Ideal for high-current battery banks and solar combiner boxes.
-
Durability: Complies with IEC 60947-2 standards for industrial-grade protection. (External DoFollow Link)
Understanding Different Types of Circuit Breakers
To build a safe home or solar system, it is important to know the different types of circuit breakers available:
-
Miniature Circuit Breaker (MCB): Standard protection for households, like our TOB7Z-63 for DC.
-
Air Circuit Breaker (ACB): Used for massive industrial currents where air is the quenching medium.
-
Earth Leakage Circuit Breaker (ELCB): Critical for safety, an earth leakage circuit breaker detects current leakage to prevent electric shocks.
-
PSX Circuit Breaker: Often confused with electrical gear, a psx circuit breaker is actually a stock market term (Pakistan Stock Exchange) used to halt trading during extreme volatility. For electrical safety, you need a hardware-based circuit breaker protection system.
