Product FAQs
7 answersWhat panelboards are compatible with the THHQB1115 circuit breaker?
This bolt-on breaker is designed for use in GE A-Series panelboards and ReliaGear Lighting panelboards.
Is the THHQB1115 breaker HACR rated?
Yes, it is HACR rated, making it suitable for use with heating, air conditioning, and refrigeration equipment that requires this specific protection.
Can the THHQB1115 be used for switching fluorescent lighting loads?
Yes, this 15-amp breaker carries an SWD (Switching Duty) rating, meaning it is UL listed for safely switching 120VAC fluorescent lighting loads on a regular basis.
What is the difference between a THQB1115 and a THHQB1115?
The primary difference is the interrupting rating. The standard THQB1115 is rated at 10kAIC, while the THHQB1115 has a higher interrupting capacity of 22kAIC. They share the same physical dimensions and bolt-on mounting style.
Can I use the THHQB1115 to replace a standard THQB1115?
Yes. Because the THHQB1115 has a higher interrupting rating (22kAIC) than the THQB1115 (10kAIC), it can safely replace the standard version in applications where a 10kAIC or 22kAIC rating is required.
How does the THHQB1115 install into the panelboard?
It features a bolt-on connection type, meaning it physically bolts directly to the bus connections of compatible load centers and lighting panels. This provides a secure, vibration-resistant connection compared to standard plug-in breakers.
What type of trip mechanism does the THHQB1115 use?
It utilizes a fixed thermal-magnetic trip unit with Long-Time and Instantaneous (LI) functions. The thermal element responds to sustained overloads, while the magnetic element provides instantaneous tripping during short circuits.
