Product FAQs
6 answersWhich panelboards accept the QBH1030EP circuit breaker?
This bolt-on breaker is specifically designed for use in classic Commander, CEB, and Sylvania bolt-on panelboards. It is not compatible with standard Eaton BR or CH series load centers.
What does the EP designation mean on the QBH1030EP?
The EP suffix indicates Ground Fault Equipment Protection. It features a 30mA trip sensitivity calibrated to protect industrial equipment and heat tracing systems from damaging ground faults, rather than the 5mA threshold used for personnel protection.
How do you wire the neutral on the QBH1030EP?
This breaker is equipped with a pigtail neutral wire. The pigtail must be routed and terminated directly to the neutral bus bar in the panelboard to power the ground fault detection circuitry.
How does the QBH1030EP differ from standard QB series breakers?
The QBH designation indicates a high-interrupting rating of 22kAIC at 120V. Standard QB series breakers share the same physical dimensions and bolt-on mounting but are rated for a lower 10kAIC interrupting capacity.
What does the LIG trip function code mean for this breaker?
LIG indicates that the breaker provides Long-Time thermal overload, Instantaneous magnetic short-circuit, and Ground-Fault equipment protection trip functions in a single unit.
Is the QBH1030EP suitable for HVAC applications?
Yes, this breaker is HACR rated, making it suitable for use with heating, air conditioning, and refrigeration equipment that requires a 30A ground fault equipment protector.
