The GE ABB THQB21100 is a compact, one-inch-wide-per-pole, thermal-magnetic circuit breaker. It is designed to interrupt current flow when a fault (overload or short circuit) is detected, protecting the electrical circuit from damage. The bolt-on connection provides a stable and secure connection to the panelboard bus bars, distinguishing it from plug-in models.
-
Compact Design: One inch wide per pole, saving space in the panel.
-
Thermal-Magnetic Protection: Offers both long-time (overload) and instantaneous (short-circuit) protection functions (LI trip).
-
Enhanced Safety: Features a quick-make/quick-break mechanism, common trip bars for multi-pole faults, and easy-to-spot trip indication.
-
HACR Rated: Suitable for heating, air conditioning, and refrigeration applications.
- Durable Construction: Made with a heat-resistant thermoset case material.
