• Voltage rating: 16040 V
• Type: FAF-series circuit breaker

Why choose the FAF16040V?

Authentic Square D engineering means this breaker is built to the same standards as the originals in your panel. The part number FAF16040V is the most reliable reference for compatibility, so double-check it against your panel label before ordering. This unit is specifically designed for applications that demand reliable interruption at 40 amps while maintaining the panel’s protection scheme and trip characteristics.

What it’s ideal for

• Maintenance and servicing of existing Square D installations where FAF-type breakers are specified
• Retrofits that require exact amperage and voltage ratings to maintain code-compliant protection
• Replacement of a failed or nuisance-tripping breaker in compatible panels

Installation and best practices

Before installing, power down the circuit and verify the panel’s compatibility list. Confirm that the panel accepts FAF-series breakers and that the FAF16040V matches the required trip curve and rating. When in doubt, consult the panel manufacturer’s guidance and follow all electrical codes. Handle with care, and ensure the breaker seats fully in the bus and snaps into place securely.

Practical tips

• Keep a spare FAF16040V on hand for planned maintenance to minimize downtime.
• Record the replacement in your facility’s electrical log for future reference and compliance audits.
