Product FAQs
6 answersWhich panelboards are compatible with the QBHCAF1020 circuit breaker?
This breaker is specifically designed as a bolt-on replacement for classic CEB, Sylvania, and Commander Electric B and BC series bolt-on loadcentres. It features a 3/4-inch form factor to fit the busbar spacing of these legacy panels.
What is the difference between Eaton QBH and BAB bolt-on breakers?
While both are bolt-on breakers, QBH breakers have a narrower 3/4-inch form factor per pole and are designed specifically for legacy Canadian panels like Commander, CEB, and Sylvania. BAB breakers have a standard 1-inch width per pole and fit standard Cutler-Hammer or Eaton bolt-on panelboards.
What type of arc fault protection does the QBHCAF1020 provide?
It is a Combination Arc Fault Circuit Interrupter (CAFCI). This means it detects and mitigates both parallel and series arcing faults to help prevent electrical fires, while also providing standard thermal-magnetic overload and short-circuit protection.
How is the neutral wire connected on this AFCI breaker?
The QBHCAF1020 features a pigtail neutral connection. The coiled white pigtail wire must be routed and connected directly to the neutral bus bar in the panelboard to ensure proper arc fault detection.
Is the QBHCAF1020 rated for switching fluorescent lighting or HVAC equipment?
Yes, this 20-amp breaker is SWD (Switching Duty) rated for 120 VAC fluorescent lighting applications and HACR rated for use with heating, air conditioning, and refrigeration equipment.
Does this breaker include diagnostic features for tripped circuits?
Yes, the QBHCAF1020 includes an LED visual trip indicator. This helps electricians quickly diagnose whether a trip was caused by an arc fault or a standard overload condition.
