Resolve polarity before wiring

The current table lists 6–63 A, B/C curves, 1P through 4P and pole-dependent DC voltages up to the stated four-pole configuration. It also lists 6 kA, whose applicable voltage and connection conditions must be confirmed. These entries do not settle the inconsistency between polarity descriptions in the surrounding prose.

Request the delivered unit’s terminal markings, exact order code and approved diagram. Assess normal and possible fault-current directions for the actual source arrangement. Do not use this article to infer a battery or PV wiring recipe, or assume a generic label permits bidirectional interruption.

JCB3-63DC procurement requires a confirmed polarity diagram. The current public listing contains inconsistent polarity wording, so its title alone cannot determine the permitted current direction of the delivered version.

The JCB3-63DC MCB’s compact and durable design makes it easy to install and ensures long-term reliability. Its polarized DC configuration further enhances its versatility, making it suitable for a variety of DC circuit protection applications.

Часто задаваемые вопросы

Is JCB3-63DC polarity-sensitive?

The reviewed public wording is inconsistent. Obtain the exact supplied version’s markings and wiring instructions before installation.

Is 1000 V available from a single pole?

The table assigns different voltage ratings to different pole configurations. Do not apply the four-pole value to one pole or improvise series connections.

Does its DC label establish any battery application?

No. Confirm voltage, перебойный ток, permitted direction and source conditions for the actual battery circuit.

What needs to accompany a JCB3-63DC order?

Request the full code, current and curve, pole arrangement, voltage-specific fault-duty information and approved polarity diagram. Resolve discrepancies before release.
