GE CK12BE300 24 – Heavy-Duty Industrial Contactor

In stock

Product Introduction

The CK12BE300 24, manufactured by General Electric (GE), is a 3-pole heavy-duty electromagnetic contactor designed for high-power motor and load control. The “24” denotes a 24–28V AC/DC universal coil, enabling compatibility with both AC and DC control circuits. Built for industrial durability, it switches high-current loads up to 300 HP at 600V AC, serving as a core component in motor control centers (MCCs) and industrial automation systems.

Key Features

Universal 24V AC/DC Coil
- Accepts 24–28V AC or DC control signals, eliminating coil-type selection and simplifying inventory.
- Stable pull-in and drop-out voltages ensure reliable operation in fluctuating control circuits.
High-Power Switching Capacity
- 3-pole design handles 300 HP (224 kW) at 600V AC, ideal for large motors and inductive loads.
- Silver-alloy main contacts resist arcing and wear, extending electrical life under heavy cycling.
Robust Industrial Construction
- Reinforced thermoplastic housing withstands vibration, dust, and harsh industrial environments.
- Compact, panel-mountable form factor integrates easily into MCCs and control cabinets.
Integrated Auxiliary Contacts
- 1 NO + 1 NC auxiliary contacts enable status feedback, interlocking, and control circuit logic.
- Auxiliary contacts rated for 10A @ 600V AC, supporting secondary control functions.
Long Electrical & Mechanical Life
- Designed for millions of mechanical operations; silver-alloy contacts minimize arcing damage.
- Low coil power consumption reduces heat buildup and extends service life.
