CNC Electric DC 2 Pole MCB 500V (YCB8-63PV) – Solar PV String Breaker 20A–63A

Compare the DC MCB 500V price in Pakistan for the CNC Electric YCB8-63PV two pole solar breaker in 20A, 32A, 40A and 63A. The CNC YCB8-63PV DC 2 pole MCB sits on the DC side of a solar system to disconnect and protect strings from overcurrent and short circuits. It is resettable, so unlike a fuse it does not need replacing after it trips.

How to Choose

A 500V DC two pole breaker fits typical residential string voltages, protecting both the positive and negative conductors of a PV string. Check your string’s open-circuit voltage in cold weather before ordering; if it is close to or above 500V, step up to the 1000V four pole model. Then choose the ampere rating to suit the string current and cable size.

Frequently Asked Questions

Which rating should I pick?

Match it to your string current, cable size and inverter maker recommendation, not simply the biggest rating.

How is it different from a DC isolator?

An isolator mainly isolates. This MCB also gives overcurrent and short-circuit protection and can be reset.

Does it replace a DC SPD?

No. Surge protection is a separate device; see our DC SPD category.
