The shipped models include:

• Mitsubishi Electric S-N300 AC110V 2A2B

• Mitsubishi Electric S-N220 AC220V 2A2B

• Mitsubishi Electric S-N400 AC110V 2A2B

All products were carefully inspected, model-checked, and securely packaged prior to dispatch to ensure safe transportation and on-time delivery to the customer.

The Mitsubishi Electric S-N Series is a well-established line of heavy-duty AC magnetic contactors, designed for reliable switching and control of motors and power circuits in demanding industrial environments.

With robust construction and stable electrical performance, S-N series contactors are widely trusted in motor control centers and automation systems.

Mitsubishi Electric S-N series magnetic contactors are industrial-grade switches designed for high-power motor control and circuit switching. The "2A2B" designation indicates they are equipped with 2 Normally Open (NO) and 2 Normally Closed (NC) auxiliary contacts as standard.

Key Features & Advantages

Wide Coil Voltage Options

Supports common control voltages such as AC110V and AC220V, suitable for various control systems.

Auxiliary Contacts: 2A2B

Each model is equipped with 2 Normally Open (NO) + 2 Normally Closed (NC) auxiliary contacts, enabling flexible interlocking and control logic.

High Reliability & Long Electrical Life

Designed for frequent switching operations under heavy loads. Features a unified white design and an advanced extinguishing mechanism that reduces arc space by approximately two-thirds compared to older models.

Compact and Robust Design

Easy installation and long-term stable operation in control panels. Designed for surface mounting with mechanical lug connections. 

Genuine Mitsubishi Electric Quality

Manufactured in accordance with international standards to ensure safety and durability. Compliant with international standards including IEC, EN, UL, CSA, and CE.

Magnet Performance

Utilizes a spiral kick-out spring to reduce bouncing and improve core life, allowing the contactor to withstand voltage drops down to 35% while closed.

Component Identification

S-N: Model series (Non-reversing contactor).

Numerical Value (220/300/400): Represents the frame size and current rating.

AC110V/220V: Specifies the required control circuit voltage to energize the coil.

2A2B: Auxiliary contact configuration (2NO + 2NC).
