Product details

The 25 A continuous rating at 40 °C is the load it carries without tripping; the electronic MicroLogic 4.1 trip unit adds thermal memory (20 minutes before and after tripping), so it remembers prior heating and won't nuisance-trip on a reclose after a brief overload.

Front-connect terminals accept compression lugs or busbars; connection pitch is 35 mm with spreaders, 27 mm without. The 9-module width (108 mm) fits standard DIN-rail enclosures. IP40 front face, IK07 impact resistance — suitable for panel interior, not washdown zones.

Frequently asked questions

Where can I buy C11B34V025B and what is the lead time?

This part is sourced to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm lead-time and price.

What is the closest alternative to C11B34V025B in the ComPacT family?

Within the ComPacT NSXm range, the closest sibling would share the same 3-pole, 25 A frame but differ in trip-unit technology (thermal-magnetic vs electronic) or earth-leakage integration. The MicroLogic 4.1 electronic trip with integrated earth-leakage is the distinguishing feature here — a standard thermal-magnetic NSXm without the Vigi module would be a different order code.

What compliance documentation does Schneider provide for C11B34V025B?

The part is certified to EN/IEC 60947-2. Schneider typically provides a Declaration of Conformity covering the applicable EU directives (Low Voltage, EMC, RoHS) and can supply UL/CSA recognition documentation on request through the RFQ process.
