Key Features

High-Performance Specs - Rated at 40A (Ith) and 660V (Ui), fully compatible with AC 240V/440V systems. This heavy-duty cam switch is built to handle high-current electrical loads with long-lasting stability
3-Pole 3-Stage Design - Features a 3-stage, 12-terminal internal structure that supports 3-pole switching. Perfect for managing complex multi-circuit configurations or simultaneously controlling three phases
Stable Maintained Action - Designed with a stay-put (non-momentary) mechanism. The handle clicks firmly into each 1-0-2 (ON-OFF-ON) position and remains locked in place, preventing accidental shifts or spring-back
Durable & Protective Enclosure - Comes with a high-quality, impact-resistant exterior master box. It provides excellent dust and splash protection, making it reliable for harsh industrial or outdoor environments
Multi-Purpose Application - An ideal solution for motor starting, reversing, and speed regulation. It also functions perfectly as a manual transfer switch (MTS) for backup generators or as a universal selector in industrial panels
