Product FAQs
8 answersWhich Siemens panelboards accept the B220AFCH breaker?
This bolt-on breaker is compatible with Siemens P1, P2, P3, P4, and P5 panelboards. It is designed to fit in positions that accept BL or BAFH frame circuit breakers.
How is the neutral connection configured on this AFCI breaker?
The B220AFCH utilizes a pigtail neutral wire. This pigtail must be routed and connected directly to the panelboard neutral bus to power the internal arc fault monitoring circuitry.
What are the accepted wire gauges and torque specifications for the load terminals?
The load lugs accept 14-10 AWG copper or 12-10 AWG aluminum conductors. For a secure connection, the terminal screws should be tightened to 25 lb-in of torque.
Does this breaker provide combination arc fault protection?
Yes, it is a Combination Arc-Fault Circuit Interrupter (CAFCI). It detects both high-energy parallel arcs and low-energy series arcs to mitigate the risk of electrical fires.
Can the B220AFCH be used to control lighting or HVAC loads?
Yes, it carries both SWD (Switching Duty) and HACR (Heating, Air Conditioning, and Refrigeration) ratings, allowing it to be used for switching fluorescent lighting and protecting HVAC equipment.
How does the B220AFCH differ from the standard B220AFC?
The "H" in the B220AFCH catalog number designates a high interrupting capacity. It provides a 22kAIC rating, whereas the standard B220AFC is rated for 10kAIC.
What is the Insta-Wire feature on this Siemens breaker?
Insta-Wire technology means the terminal screws are shipped backed out and ready for wire insertion. This saves electricians time during installation by eliminating the need to loosen the screws first.
What does the LI trip function code mean on this breaker?
LI stands for Long-Time and Instantaneous trip functions. The long-time function provides thermal overload protection, while the instantaneous function provides magnetic short-circuit protection.
