Siemens | QJ3M080HL | Circuit Breaker | 80A | 3-Pole | 240V

Siemens QJ3M080HL is a robust 3-pole, 80-amp circuit breaker designed for 3-phase 240V electrical systems, ideal for maintenance, retrofit, and replacement projects where reliable overcurrent protection is essential.

Why this matters: In commercial and light industrial environments, a properly matched breaker keeps critical equipment safeguarded while minimizing downtime during panel upgrades. The 3-pole design protects all three hot legs, helping balance loads across your three-phase distribution and simplifying wiring in Siemens-compatible panels.

Key specifications

• Amperage: 80A
• Poles: 3-Pole
• Voltage: 240V
• Part number: QJ3M080HL
• Intended use: Maintenance, retrofit, and replacement

Important compatibility note

Always confirm fit and ratings before ordering. The QJ3M080HL part number is the most reliable reference for compatibility with your Siemens panel or enclosure.

Ideal applications

Best suited for 3-phase commercial or light industrial environments that operate on 240V. Use it to upgrade aging panelboards, replace worn breakers, or implement a retrofit plan when expanding service capacity.

What makes it stand out

• Direct fit for Siemens QJ-series panels and common 3-phase distributions
• Clear replacement lineage with the QJ3M080HL part number
• Efficiently protects all three phases in a single, integrated unit

Practical tips for a smooth replacement

• Check your panel labeling to verify that QJ-series breakers are supported
• Match the circuit’s amperage and voltage to the 80A, 240V rating
• De-energize the panel and follow safety procedures before replacement
• Retain the original part number for future ordering and service records
