Leviton Telcom MS4X-303 Motor Starter Toggle Switch 3P

Product Description

The LEVITON TELCOM MS4X-303 is a manual motor starter toggle switch in an enclosed 3-pole configuration. Manual motor starters provide manual on/off control of a motor circuit while also offering overload protection to prevent damage from sustained overcurrent conditions. This enclosed design protects internal switching components from dust and incidental contact. Electricians and maintenance technicians install this type of device in light commercial and industrial motor branch circuits where a simple, local disconnect and overload protection point is required.

The MS4X-303 is suited for 3-phase motor branch circuit applications where a compact, manually operated starter is needed. Its toggle switch operation allows for straightforward local control without requiring a separate contactor or control circuit. This type of enclosed manual motor starter is commonly installed on small machinery, pumps, fans, and compressors requiring a dedicated local disconnect point with built-in overload protection.

Key Features

• 3-pole configuration for 3-phase motor circuit control
• Toggle switch operator for direct manual on/off control
• Enclosed housing protects internal components from dust and incidental contact
• Built-in overload protection guards the motor against sustained overcurrent
• Compact form factor suitable for panel mounting in tight spaces

Compatibility

Designed as an OEM-style replacement or direct-install manual motor starter for enclosed 3-pole toggle switch applications in light commercial and industrial motor branch circuits.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and any applicable local codes. De-energize and lock out/tag out the circuit before mounting or wiring the device. Verify that the motor full-load amperage falls within the starter's rated overload range before energizing. Do not bypass or defeat the overload protection mechanism.
