@PEN OB12Z-63 DC MCB 2P 63A 500V DC – Double Pole Solar & Battery Circuit Breaker

@PEN OB12Z-63 DC MCB 2P 63A 500V DC – Double Pole Solar & Battery Circuit Breaker

@PEN OB12Z-63 is a reliable 63A DC MCB rated 500V DC. This double-pole (DP) breaker protects solar PV systems, battery installations, EV-charging points and industrial DC circuits from overcurrent and short circuit.

Why use a DC MCB?

DC current does not cross zero like AC, so the arc is much harder to stop. A DC-rated breaker like the OB12Z-63 is built to break DC faults safely and protect your cables, batteries and inverter.

Key Features

• Rated current 63A
• Rated voltage 500V DC
• Double-pole (2P) — protects both + and − lines
• Overcurrent and short-circuit protection
• Short-circuit breaking capacity approx. 6kA
• IP20 terminal protection, copper terminals
• Compact size, standard 35mm DIN-rail mounting

Applications

• Home solar systems (12V / 24V / 48V and PV strings up to 500V)
• Battery to inverter / IPS lines
• DC distribution panels
• EV-charging DC lines
• Industrial DC control circuits

Installation tips

• Switch the system OFF and cover the solar panels before wiring.
• Follow the + and − marks printed on the breaker — DC breakers are polarity-sensitive.
• Use cable of the right size for the current and tighten terminals firmly.
• Mount on a standard 35mm DIN rail inside a proper DC distribution box.

Frequently Asked Questions

What is a DC MCB?

A circuit breaker made to protect DC circuits from overload and short circuit.

Can I use it in a 48V solar system?

Yes. 500V DC rating covers 12V, 24V and 48V systems and small PV strings.

Why double pole?

2P breaks both positive and negative lines together for full isolation.

Is 63A enough for my system?

Choose a breaker slightly above your normal working current. Call us and we will help you pick the right size.
