Product Overview

PXB6DC-125M is a DC circuit breaker 125A for 1P DC 24–125V; 2P DC 24–250V applications. It is intended for PV, telecom, energy-storage or control circuits when the DC fault study supports the rating; this describes an evaluation context, not a universal approval. Confirm the complete circuit design before specifying the product.

DC overload and short-circuit protection is distinct from adjacent protection functions. Do not infer AC/DC suitability, residual-current protection, automatic control or isolation performance from the product family name alone.

Key Features

  • High Dielectric Strength: Rated insulation voltage up to 500 V and 4 kV impulse withstand voltage, ensuring robust protection in demanding DC environments.
  • Superior Short-Circuit Protection: High breaking capacity with an ultimate breaking capacity (Icu) of 10 kA and a service breaking capacity (Ics) of 7.5 kA.
  • Wide Voltage Rating: Suitable for DC systems from 24 V up to 250 V (1P: up to 125V; 2P: up to 250V), perfect for energy storage, EV infrastructure, and telecom.
  • Published pole options: 1P / 2P.
  • Published electrical context: 1P DC 24–125V; 2P DC 24–250V.
  • Primary function: DC overload and short-circuit protection.
  • Selection reference: 10kA Icu; 7.5kA Ics.
  • Applicable standard reference: IEC 60947-2 references.
  • Final selection must use the exact model table, drawings and installation instructions.

Typical Applications

PV, telecom, energy-storage or control circuits when the DC fault study supports the rating. Verify system voltage, expected fault current or leakage, wiring arrangement, environment, coordination and applicable rules for the ordered configuration.

PXB6DC-125M Product FAQ

What is the PXB6DC-125M used for?

The PXB6DC-125M is specified for DC overload and short-circuit protection in 1P DC 24–125V; 2P DC 24–250V applications, within the ratings and configurations listed in its technical table. Final suitability depends on the complete circuit design.

How does the PXB6DC-125M work?

Its operating principle follows the documented function: DC overload and short-circuit protection. Use the exact model documentation for thresholds, timing, trip behaviour, terminals and test procedures.

How do I choose the PXB6DC-125M rating and poles?

Start with the design current and system arrangement, then choose only a published option. The page lists pole options as 1P / 2P; confirm neutral, polarity, conductors and isolation requirements.

What safety limitation applies to the PXB6DC-125M?

Do not treat the PXB6DC-125M as a universal substitute for another device. Confirm 10kA Icu; 7.5kA Ics, the system voltage, fault or leakage conditions and any separate upstream protection before selection.

Can the PXB6DC-125M be used in another circuit type?

Only when the exact ordered configuration is rated for that circuit. AC and DC duties, residual-current devices, isolators, smart controls and voltage protectors are not interchangeable by appearance or current rating.

How should the PXB6DC-125M be installed and tested?

Use the exact product drawing, terminal identification and instructions. A qualified person should verify isolation, conductors, torque, settings, coordination and functional tests before energising the circuit.

Confirm the Right PXB6DC-125M Configuration

Send the model, rating, poles, system voltage, application, quantity and document requirements. CHAC will review the request against the published data.
