Compatibility & installation tips

Before ordering, verify that your system requires a 30A, 3-pole, 600V breaker and that HLA360306 is the correct replacement part. The part number is the best reference for compatibility with your panel or enclosure. For a safe and reliable replacement, disconnect power to the circuit, follow all applicable codes, and consult a qualified electrician if you’re unsure about the installation.

Practical guidance and maintenance insights

• Keep a spare HLA360306 on hand for planned maintenance or corrective replacements to minimize downtime.
• When replacing, ensure the panel’s labeling and the breaker’s trip characteristics align with your system requirements to maintain code compliance.
• Document the replacement with the part number (HLA360306) and date for efficient future servicing and audits.
