Product details

The Schneider Electric C11H34V050B is a ComPacT NSXm moulded-case circuit breaker with 3 poles, rated 50 A at 40 °C and a 70 kA interrupting capacity at 415 V AC — the H performance level. It carries a MicroLogic 4.1 electronic trip unit with integrated earth-leakage protection, adjustable from 30 mA to 5 A in class A or AC sensitivity. Built to EN/IEC 60947-2, it is a distribution-grade MCCB for panelboards, switchboards, and sub-distribution in commercial or light industrial sites.

The MicroLogic 4.1 is a fixed-curve electronic trip unit — no field-adjustable long-time or short-time pickup, but it includes thermal memory that remembers the last 20 minutes of heating before and after a trip, preventing nuisance reclosure on a hot cable. Integrated earth-leakage protection means this single device covers both overcurrent and ground-fault in one package — no separate RCCB or RCBO needed. Sensitivity choices cover 30 mA (personnel protection) up to 5 A (equipment protection), selectable by the installer.

Mounting and integration notes

Mounts on a backplate in horizontal or vertical orientation — flat on the back. The 9-module pitch (108 mm wide, 144 mm high, 80 mm deep) fits standard 35 mm DIN-rail enclosures with spreaders; without spreaders the connection pitch is 27 mm. Front connections top and bottom accept compression lugs or busbars. IP40 front face, IK07 impact resistance — suitable for enclosed panel installation, not for washdown areas.

Frequently asked questions

Where can I buy C11H34V050B 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 — no stock or lead-time figures are published here.

What is the closest alternative to C11H34V050B in the same family?

Within the ComPacT NSXm range, the closest peer would share the same frame (NSXm 63H) and pole count but differ in trip unit rating or earth-leakage sensitivity. No pin-compatible direct substitute is listed; the exact order code should be matched for a BOM line.

What compliance documentation does Schneider provide for C11H34V050B?

The breaker is certified to EN/IEC 60947-2. The manufacturer typically provides a Declaration of Conformity covering the applicable EU directives; specific RoHS, REACH, and UL documentation should be requested at quote time.
