63 A MCCB with 75.6 kA interrupting capacity — line protection for distribution panels
The Siemens SENTRON 3VA1063-3ED36-0AF0 is a 3-pole molded case circuit breaker (MCCB) rated for 63 A continuous at 40 °C, with a thermal-magnetic TM210 release designed for line protection in distribution panels. It interrupts fault currents up to 75.6 kA at 240 V, 52.5 kA at 415 V, and 32 kA at 440 V — covering the typical fault-current range for commercial and light industrial feeder circuits. Rated current holds at 63 A from 40 °C through 50 °C, then tapers to 58 A at 70 °C — a thermal curve that matches the typical panel ambient.
Interrupting ratings and trip indication — what they mean for fault coordination
The built-in trip indicator gives a visual flag when the breaker has opened on fault, speeding fault isolation on a multi-breaker panel.
Lifecycle and sourcing — current production, quoted to order
This 3VA1063-3ED36-0AF0 carries a lifecycle status of current production, meaning it remains an active catalog line from Siemens. No last-time-buy or phase-out notice is on record.
Panel integration — DIN-rail mount, auxiliary switch provision
The 130 mm height leaves clearance for busbar connections in a standard enclosure.
