I'm reading through the install sheet for an Intermatic IG1200RC3 and there's something confusing. The section under a Type 2 install reads:
For best performance from SPD the maximum recommended circuit breaker size of 240V, 20A, 2-pole should be used.
Why would the breaker size matter? If the breaker were ever to trip, the device would be disconnected from the panel and offer no protection. If the breaker does not trip, the device should receive full current as if there was no breaker at all. (I'm intending to use a spare breaker in the bottom right position, to protect various compressors, pumps and electrical equipment on the other breakers).
