Interrupting capacity and selectivity headroom
The 3VA2063-5HL32-0CL0: At 240 V the breaker clears 187 kA — that is full-range fault protection right at the service entrance or main tie, where available fault current is highest.
Thermal derating curve — the real current rating
Above that it derates: 60.6 A at 55 °C, 58.3 A at 60 °C, 55.9 A at 65 °C, and 53.6 A at 70 °C. 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.
