Lifecycle and sourcing reality
The part carries a 4-pole 100% N-conductor protection design, meaning the neutral pole is fully rated — no derating needed for unbalanced loads or harmonic-rich circuits. Insulation voltage is rated 800 V, so it's suitable for 690 V systems with margin. Power loss is 19 W maximum at rated current — negligible for panel thermal budgeting but worth noting if you're packing multiple breakers in a sealed enclosure.
Panel integration and compliance
Dimensions are 130 mm height, 101.6 mm width, 70 mm depth — a standard SENTRON 3VM frame that fits existing Siemens switchboard and panelboard cutouts. IP40 on the front means it's protected against tools and small wires entering the breaker face, but not against dust ingress; mount in a clean, dry enclosure. No undervoltage release, no voltage trigger, no communication function — this is a basic thermal-magnetic breaker with no aux contacts or shunt trip built in. The overcurrent release design is TM220 — a fixed thermal bimetal and fixed magnetic trip. No trip indicator, no ground-fault monitoring. If you need adjustable long-time or short-time pickup, look at the 3VA series with electronic trip units. For simple overload and short-circuit protection on a feeder or main, the TM220 is reliable and field-proven.
