This kit is compatible with revised P1 interiors and supports circuit breaker types QR2, QRH2, HQR2, and HQR2H in three-phase systems, rated up to 225 amps. All necessary mounting hardware is included, while the circuit breaker itself is sold separately. Note that this kit is not suitable for use with original P1 models made prior to January 2015.
This mounting kit ensures proper installation for breakers in updated P1 interiors.
