Siemens | QJ3M090HL | Circuit Breaker | 90A | 3-Pole | 240V | Bolt-On

Siemens QJ3M090HL is a 90A, 3-pole circuit breaker engineered for reliable protection in 240V electrical systems. The bolt-on design delivers a secure, vibration-resistant installation, making it a practical choice for maintenance, retrofit, and replacement projects where exact specifications matter.

• Amperage: 90A
• Poles: 3-Pole
• Voltage: 240V
• Mounting: Bolt-On
• Part number: QJ3M090HL
• Compatibility note: Confirm fit and ratings before ordering; the part number is the best reference for compatibility.

Key benefits and what you can expect:

• Secure, durable protection for three-phase circuits powering motors, compressors, and heavy machinery in commercial or industrial panels.
• Designed to fit panels and enclosures that require a bolt-on mounting method, reducing installation time and the risk of loose connections.
• Simplified maintenance and retrofitting workflows: when a panel upgrade or equipment replacement is needed, this 3-pole 240V breaker yields fast compatibility with Siemens systems.
• Clear identification and reliable performance under typical industrial load profiles, helping you avoid nuisance trips and ensure continuity of service.
