Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the breaker is sold with additional switching functions beyond overcurrent protection
8536.50 covers other switches, which may apply if the product includes manual switching capabilities as a primary function.
If imported as part of a load center assembly with busbars and enclosures
8537.10 covers boards, panels, and consoles for electric control or distribution, which may apply if the breaker is integrated into a complete distribution panel.

Import Tips & Compliance
• Ensure the breaker is rated for 60 Hz and CSA-certified, as CBSA may require proof of compliance with Canadian electrical standards
• Declare the correct voltage and amperage ratings on the commercial invoice to avoid reclassification
• If importing multiple units, consider consolidating shipments to reduce per-unit brokerage fees
