This page lists the DC breaker 125A price in Pakistan for the CNC Electric YCB8s-125PV single pole solar and battery breaker. The CNC YCB8s-125PV is a single pole DC miniature circuit breaker rated 500V and 125A for photovoltaic and battery protection. Its DC-rated arc chute is designed to extinguish the sustained arc that a standard AC breaker cannot handle.

Key Features

• Rated 500V DC and 125A
• DC arc chute built for photovoltaic and battery use
• Polarity sensitive: supply to the top terminal, load to the bottom
• Suited to high-current DC strings and battery bank feeds
• Single pole, compact MCB format

Where to Use

• Main disconnect for 48V lithium or lead-acid battery banks
• Solar charge controller output breaker
• DC bus protection in hybrid inverter setups
• Industrial DC motor feeds

How to Choose

High-current DC circuits behave differently from household AC. DC current does not pass through zero, so an arc is harder to break, and that is why this breaker has a DC arc chute and a defined polarity. When you install it, connect the supply to the top terminal and the load to the bottom terminal as marked. Choose the 125A rating for battery feeds and DC bus lines where the cable and the inverter or charge controller current call for it, and keep the wiring short and well terminated.
