Product details

The SENTRON 3VA1163-5EF36-0KH0 is a 3-pole molded case circuit breaker rated for line-protection duty, carrying a continuous current of 63 A at 40 °C ambient — no derating needed up to 50 °C, where it still holds 63 A (cites:,). Above that, it drops to 62 A at 55 °C and 58 A at 70 °C (cites:,).

Deployment context — panel integration and auxiliaries

This breaker mounts on a DIN rail or panel plate — the 76.2 mm width (3 in) and 130 mm height (5.12 in) fit standard SENTRON 3VA cutouts (cites:,). Depth is 70 mm (2.76 in), which leaves clearance for rear terminals and wiring ducts (cite:). No undervoltage release is fitted (cite:). Max power loss is 17.3 W — factor that into enclosure thermal rise if the panel is sealed (cite:).

Operating range and environmental limits

The thermal-magnetic trip curve is calibrated for the listed current ratings across that span — no additional compensation needed. The unit includes a trip indicator (cite:). No communication function is built in (cite:); this is a standalone line-protection device, not a smart breaker.

Frequently asked questions

What are the key ratings for 3VA1163-5EF36-0KH0?
