Schneider Power Contactors Manufacturers In Morogoro

What Is a Schneider Contactor

A Schneider contactor is an electrically controlled switch used for switching a power circuit, mainly in industrial control systems. It allows remote control of motors, lighting, heating, and other electrical loads without direct manual handling of high voltage.

How the Contractor Functions

The contactor operates via an electromagnetic coil that, when energized, pulls in contact points to close a circuit. Once de-energized, a spring returns the contacts to the open position. This mechanism ensures fast, reliable switching even under high current.

Key Internal Components

• Electromagnetic Coil – Activates the switching mechanism
• Power Contacts – Carry the main load current
• Auxiliary Contacts – Handle signaling or control operations
• Arc Chutes – Safely extinguish electrical arcs during switching
• Frame & Housing – Made from high-strength insulation materials

Notable Features of Schneider Contactors

• Wide Current Range – Available from 9A to over 800A
• Compact Modular Design – Easily fits in panels and MCCs
• Low Power Consumption Coils – Reduces energy demand
• High Electrical & Mechanical Life – Up to millions of operations
• CE, IEC, and UL Compliant – Meets international standards for safety
