Product details

MCCB for distribution panels — 25 A, 4P, 70 kA breaking capacity

The MicroLogic 4.1 electronic trip unit provides adjustable thermal memory (20 minutes before and after tripping) and integrated earth-leakage protection with selectable sensitivity from 30 mA to 5 A (class A and AC). That eliminates the need for a separate earth-leakage relay in most distribution boards — one device, one DIN-rail footprint. Rated to EN/IEC 60947-2, pollution degree 3, overvoltage category IV. IP40 front face, IK07 impact resistance.

Width 108 mm (12 module pitches of 9 mm), depth 80 mm, height 144 mm. Front-connect terminals accept compression lugs or busbars; connection pitch is 35 mm with spreaders, 27 mm without. Neutral on the left. Toggle control, local signalling flag for auxiliary contacts. Fits standard backplate mounting — no DIN rail adapter needed.

Frequently asked questions

Where can I buy C11H44V025B and get a price?

Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time.

What is the breaking capacity of C11H44V025B?

70 kA at 415 V AC (performance level H), certified to EN/IEC 60947-2. That is the maximum fault current it can safely interrupt at that voltage.

Does the C11H44V025B include earth-leakage protection?

Yes, integrated earth-leakage protection is built into the MicroLogic 4.1 trip unit. Sensitivity is selectable from 30 mA to 5 A for both class A and class AC leakage types.

What compliance documentation is available for C11H44V025B?

The breaker is certified to EN/IEC 60947-2, pollution degree 3 per IEC 60664-1, overvoltage category IV. IP40 and IK07 per IEC 60529 and IEC 62262. Standard Schneider documentation (declaration of conformity, CE, UKCA, EAC) is available on request.
