When you plan a solar array, battery energy storage system (BESS), EV charging setup or other DC‑powered installation, you want a circuit breaker that handles the voltage and current safely. Kripal offers a range of DC‑rated miniature circuit breakers (MCBs) whose voltage and current ratings cover a broad spectrum, from small systems to high‑voltage DC grids.

DC Voltage Range for Kripal DC Breakers

Kripal’s DC MCB product family is rated to handle DC voltages up to 1000 V under standard configurations. These breakers support currents up to 63 A, with a breaking capacity up to 6 kA. They are appropriate for photovoltaic (PV) string protection, small battery circuits, telecom DC power supplies, and other low‑ to medium‑power DC applications.

For larger or high‑power DC systems, Kripal offers DC MCCBs. Models such as from the UKM5DC series support DC working voltages of 1000 V and, in some variants, insulation or operational rating up to 1500 V DC.

These MCCBs cover current frames from 250 A up to 630 A and deliver high interrupting capacity (up to 20 kA) to handle potential fault currents or overloads in large battery banks, solar farms, EV infrastructure or industrial DC distribution systems.

In other words, whether your system is a small off‑grid solar array or a large-scale energy storage or DC distribution network, Kripal has DC‑rated breakers with matching voltage and current capabilities.

What This Range Means for Different Projects

With the variety of voltage and current ratings, Kripal breakers match many use cases:

  • For low‑voltage DC circuits (small battery banks, telecom DC, small solar arrays), a DC MCB from Kripal gives compact and reliable protection.
  • For medium‑ to high‑voltage DC systems (large PV farms, energy storage, EV charging, DC distribution), a DC MCCB from Kripal supports heavy loads and high fault‑current potential.
  • The availability of both low-voltage and high-voltage DC devices lets designers avoid over‑rating (wasting cost and space) or under‑rating (risking safety and reliability).
  • All DC breakers from Kripal have proper DC‑rated contacts, arc suppression design, correct insulation and polarity marking. That ensures safe and correct behavior in DC circuits, unlike using AC‑rated breakers for DC, which can fail under sustained DC arcs.

What to Confirm When You Choose a Kripal DC Breaker

Before you pick a DC breaker for your system, verify the following:

  • The system’s DC voltage does not exceed the breaker’s rated DC voltage (for example 1000 V or 1500 V).
  • The load current and possible fault current stay within the breaker’s current rating and interrupting capacity.
  • The breaker type (MCB or MCCB) matches the load size, wiring arrangement, and expected fault conditions.
  • Wiring includes correct polarity, suitable DC‑rated cables and connectors, and proper insulation.
  • The installation environment and application (indoor, outdoor, PV, battery, storage, EV, telecom, etc.) are compatible with the breaker’s design and rating.
  • Proper matching between system characteristics and breaker specs ensures safety, stable operation, and protection under fault conditions.

Custom and High‑Voltage Options

Kripal’s product range also supports customized or higher‑voltage DC breakers for special requirements. For installations needing more than standard DC MCBs, such as high‑voltage battery banks, large renewable energy farms or utility‑scale systems, Kripal offers DC MCCBs with higher voltage and current ratings. These devices include enhanced arc‑suppression mechanisms, stronger insulation and design suited for heavy‑duty DC applications.

This flexibility allows system designers and integrators to get breakers tailored to their exact system demands, frame MCCBs for energy storage or distribution networks.

To sumup

Kripal provides DC‑rated breakers that cover a broad DC voltage and power range. From small DC circuits up to large‑scale systems, appropriate breakers exist for nearly every need. By verifying your system’s voltage, current, fault potential, and wiring conditions, you can choose a breaker that matches exactly.
