1.产 品 资 料 介 绍：

中文资料：

VBC6-30-10 是一款专为电动机正反转控制设计的机械互锁接触器，主要用于防止三相电机在运行中因误操作导致相同短路。以下是全面技术分析：

1. 核心特性

• 机械互锁结构：通过物理连杆机构确保两个接触器（正转/反转）无法同时吸合

• 双重保护：

  • 机械互锁（强制物理阻断）

  • 电气互锁（需外接常闭辅助触点）

• 灭弧系统：内置灭弧罩，分断能力≥10×Ie（AC-3类别）

2. 关键参数

英文资料：

VBC6-30-10 is a mechanical interlocking contactor designed specifically for forward and reverse control of electric motors, mainly used to prevent the same short circuit caused by misoperation of three-phase motors during operation. The following is a comprehensive technical analysis:

1. Core Features

Mechanical interlocking structure: ensures that two contactors (forward/reverse) cannot be simultaneously engaged through a physical linkage mechanism

Double protection:

Mechanical interlock (forced physical blocking)

Electrical interlock (requires external normally closed auxiliary contacts)

Arc extinguishing system: Built in arc extinguishing hood, with a breaking capacity of ≥ 10 × Ie (AC-3 category)

2. Key parameters

Parameter specification values

Rated current (Ie) 30A (AC-3380V)

Control voltage 24VDC~380VAC (coil)

Number of poles: 3 main contacts+1NO+1NC auxiliary contacts

Electrical lifespan ≥ 1 million cycles (AC-3)

Protection level IP20 (requires installation of electrical cabinet)
