Overview
The GE THHQB32030 is a 3-pole thermal-magnetic molded case circuit breaker designed for commercial and industrial electrical distribution. With a 30-amp current rating, 240V voltage rating, and 22KA interrupting capacity, this breaker provides reliable protection against overloads and short circuits in load centers, panelboards, and lighting panels.
Key Features
- Thermal-magnetic trip mechanism for fast and reliable protection
- Bolt-on mounting for secure connection to bus bars and load centers
- Internal common trip on all three poles ensures coordinated operation
- SWD (Switching Duty) rated for use in circuits with frequent on/off switching
- HACR listed (heating, air conditioning and refrigeration applications)
- Compact 1-inch-per-pole design for efficient panel space utilization
Technical Specifications
- Current Rating: 30 amps
- Voltage Rating: 240 VAC
