The Siemens SENTRON 3VA2163-5HL36-0DH0 is a 3-pole molded case circuit breaker rated for 63 A continuous current at 40–70 °C without derating — the full thermal curve holds flat across that span, so no re-rating needed for warm enclosures. The adjustable thermal-magnetic trip covers 95 A minimum to 756 A maximum, which gives you a wide coordination window for downstream feeders or motor branch circuits. Breaking capacity runs 187 kA at 240 V, 121 kA at 415/440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V — the 690 V figure is low, so confirm system voltage before committing the BOM line.
Design and integrated accessories
The UVR drops the breaker on loss of control voltage — standard for safety disconnects or emergency-off circuits. The supplied basic switch is 3VA21635HL360AA0, so replacement or spare-parts ordering is straightforward. No ground-fault monitoring or communication module is fitted; those are separate add-ons if needed.
The 86 mm depth fits standard 200 mm deep enclosures; verify door clearance if a rotary handle or extended shaft is used.
