In a sealed panel or high-ambient machine cabinet, the effective continuous current is lower — size the load accordingly. ## Trip unit and auxiliary complement The ETU320 is an electronic release with LSI protection (long-time, short-time, instantaneous) plus ground-fault capability when paired with an external sensor — though this variant ships without ground-fault monitoring. The basic switch module is order code 3VA2063-5HL32-0AA0 and the integrated auxiliary trip is 3VA9608-0BB24. The 105 mm width occupies three 35 mm module spaces on the rail. Maximum power dissipation is 7.9 W — account for that in enclosed panel thermal calculations. ## Environmental range and endurance Mechanical endurance is 20,000 operations. The trip indicator is present for visual fault identification. This is a current-production part in the SENTRON 3VA family.","metaTitle":"3VA2063-5HL32-0CL0 SENTRON MCCB, 63 A, 3-pole, ETU320, 187 k","metaDescription":"Siemens SENTRON 3VA2063-5HL32-0CL0 molded case circuit breaker, 63 A rated, 3-pole, ETU320 release, 187 kA at 240 V.
