Part Number TQC21Y100, it combines GE’s engineering standards with easy installation for professionals and DIY electricians alike.

Key specifications

• Current rating: 100 A
• Poles: 2
• Voltage rating: 240 V
• Brand/part: General Electric, TQC21Y100

Why this GE breaker stands out

• OEM compatibility for GE panels: Designed to fit GE electrical panels that accept TQC-series breakers, helping maintain correct fit, trip performance, and panel labeling.
• Dual-pole protection: Simultaneously disconnects both hot lines in a 240V circuit, reducing the risk of unbalanced faults and improving overall safety.
• Reliable protection for demanding circuits: The 100 A rating makes it suitable for hefty loads such as main-disconnect applications and large branch circuits in residential or light commercial settings.
• Quality you can trust: As a GE component, it’s manufactured to meet established electrical standards, offering consistent performance over time.

Ideal use cases

• Replacing a failed main or branch breaker in GE panels that accept TQC-series devices.
• Protecting high-load 240V circuits in residential or light commercial electrical systems (such as large HVAC circuits, water heaters, or workshop equipment).
• Upgrading service protection where a dedicated 100 A, 2-pole breaker is required to safely manage load and maintain code-compliant disconnects.

Installation and practical tips

• Safety first: Disconnect the main power and verify absence of voltage before servicing any panel. Use proper PPE and follow local electrical codes.
• Compatibility check: Confirm that your GE panel is labeled to accept TQC-series breakers and that the bus bar type matches the TQC design.
• Torque and seating: Install the breaker firmly into the panel bus and tighten mounting screws to the manufacturer’s recommended torque to ensure secure operation and reliable trip performance.
• Clear labeling: After installation, label the protected circuit with the breaker's amperage and usage to aid future maintenance and inspections.

Whether you’re replacing a worn-out unit, upgrading a circuit, or performing regular panel maintenance, the General Electric TQC21Y100 100A 2-Pole 240V Circuit Breaker offers dependable, GE-aligned protection that keeps your 240V systems safer and more reliable. Trust in an authentic GE part to maintain proper circuit protection, consistent trip characteristics, and peace of mind across your electrical setup.
