EATON PL9-C4-2-DC Circuit Breaker

EATON PL9-C4-2-DC Circuit Breaker

Product Details Introduction

EATON PL9-C4-2-DC miniature circuit breaker is a modular miniature circuit breaker designed specifically for direct current (DC) applications, widely used in DC distribution systems such as industrial automation, power systems, communication equipment, and new energy systems. Here are its detailed product information and application areas:

1、 Basic Product Information

Product Model: EATON PL9-C4-2-DC

Type: Miniature Circuit Breaker (MCB)

Current rating: 4A

Number of poles: 2 poles (for bipolar DC applications)

Voltage level: typically supports up to 220V DC (per pole) or 440V DC (when connected in series with 2 poles)

Release curve: C-type (C Curve, suitable for medium inductive loads)

Installation method: DIN rail installation

Standard certification: Complies with IEC/EN 60947-2 or IEC/EN 60898 (DC version)

2、 Product Features

Specially designed for DC systems: Unlike ordinary AC MCBs, it is specifically designed for DC voltage breaking and has strong arc extinguishing capabilities.

Bipolar protection: Disconnect the positive and negative poles or two positive poles respectively, suitable for different DC topologies.

C-type tripping characteristic: suitable for slight inductive loads such as small DC motors, relay circuits, etc.

High breaking capacity: It has good short-circuit protection capability, commonly 6kA.

Compact structure: suitable for high-density installation in limited space.
