General Electric THQB32015 - 15A, 3-Pole, Miniature Circuit Breaker (MCB)

Introducing the General Electric THQB32015 — a 15A, 3-Pole Miniature Circuit Breaker (MCB) engineered to deliver dependable overcurrent protection for three-phase systems. Designed for compact, high-density panel installations, this GE device fits seamlessly into panelboards, switchboards, and control panels where safe, reliable operation matters most.

• Current rating: 15A — precisely matched to protect typical industrial and commercial circuits without nuisance trips, helping keep equipment and processes stable.
• Three-pole configuration — provides coordinated protection across all three phases in three-phase systems, ideal for motor drives, compressors, and multi-phase feeders.
• Miniature Circuit Breaker (MCB) type — offers automatic disconnection when an overcurrent condition is detected, safeguarding wiring and connected loads in distribution hardware.
• Compact, versatile mounting — a streamlined footprint that supports dense panel layouts and OEM enclosures, making it suitable for both retrofit and new-build installations.
• Part of GE’s trusted THQB family — built to perform consistently in industrial, commercial, and OEM applications where dependable protection is essential for motor control centers and distribution panels.

Ideal use cases

• Motor control centers and equipment rooms with three-phase circuits that require robust 3-pole protection.
• Distribution panels and switchboards in commercial facilities needing compact, reliable overcurrent protection.
• OEM equipment enclosures where a 15A, 3-pole MCB provides safe, standardized protection for multi-phase networks.

Why this matters in practical terms

Overcurrent events can ripple through a system, risking insulation damage, equipment wear, and unplanned downtime. The THQB32015 interrupts faults promptly across all three lines, helping isolate the problem quickly and protect wiring, contactors, and downstream devices—all while supporting smoother, safer operation of your electrical distribution.

Compatibility and procurement notes

• Designed for standard three-pole installations in panelboards and switchboards.
• Suitable for 15A circuits in three-phase networks commonly found in industrial, commercial, and OEM environments.
• Direct-fit option for GE-based electrical systems and newer panel configurations that require a reliable 3-pole MCB solution.
