Hello David, thanks for reaching out. What you have there is a 50 amp circuit breaker. The W29 designation on your breaker is a date code/batch number, so the replacement breaker is not required to have the same designation. As long as it is a12v 50 amp breaker it will do fine. We offer one, the Pollak # PK54250PL which is what I recommend for a replacement.
