HQ2125BH - 125Amp Circuit Breaker

HQ2125BH - 125Amp Circuit Breaker

When you're replacing a circuit breaker in existing equipment, the details that determine form, fit, and function matter just as much as the part number. The HQ2125BH circuit breaker is specified here as a 125-amp, 2-pole, plug-in thermal magnetic-trip breaker with a 100k AIC rating at 240VAC. For maintenance of legacy electrical equipment, the HQ2125BH provides technicians with a clearly defined set of electrical and physical characteristics to compare against the existing breaker and panel requirements.

Key Features and Benefits

• 125-amp rating: Provides the specified 125A current rating for compatible equipment requiring this breaker configuration.
• 2-pole design: Configured as a two-pole circuit breaker for applications that specifically require two-pole protection.
• Thermal magnetic trip: Uses a thermal magnetic-trip mechanism as specified for the HQ2125BH.
• Plug-in configuration: Designed with a plug-in connection, an important physical characteristic when determining panel compatibility.
• HQPPH type: The HQPPH designation provides another specific identifier for matching the breaker to existing equipment.
• Requires four panel spaces: Knowing the minimum four-space requirement helps technicians check panel fit before installation.

Material Compliance and Certifications

No specific material compliance declarations or certifications were included in the specifications for this HQ2125BH configuration. For that reason, no UL, RoHS, REACH, or other certification claim is being added to this description without supporting documentation.

Where It Works Best

The HQ2125BH 125A circuit breaker is suited to compatible legacy electrical equipment that specifically requires its combination of a 125A rating, two poles, 100k AIC at 240VAC, thermal magnetic trip, HQPPH type, and plug-in configuration. The four-panel space requirement deserves particular attention; even when the electrical ratings appear correct, the physical panel configuration must still match.
