1. Product Overview
2. Core Competitive Features
✅ Wide Current Range 100A–630A
Covers full specifications: 100A, 160A, 200A, 250A, 400A, 630A, meets diverse power load demands of industrial and new energy projects.
✅ Optional Single Throw & Double Throw Structure
Two structural types for selection: single throw for simple on-off isolation, double throw for dual-circuit switching & transfer power supply scenarios.
✅ High-Grade Flame Retardant Insulation Housing
Shell made of V0 grade flame retardant insulating material, high temperature resistance, anti-aging, effectively avoid circuit fire risks under overload abnormal conditions.
✅ Full Pure Copper Conductive Fittings
All contact terminals and conductive parts use thickened pure copper, excellent electrical conductivity, low contact resistance, stable power transmission without overheating under long-term heavy load.
✅ Built-In Anti-Seismic Shock Resistant Structure
Optimized internal fixed buffer structure, strong shock and vibration resistance, stable contact performance for mechanical workshop, outdoor PV station and bumpy transportation environments.
✅ Double Side Operable Design
Unique two-side operation structure, can control the switch from either left or right side of cabinet, flexible layout for compact electrical panel design.
✅ Matching Internal & External Dual Purpose Handle
Comes with integrated operating handle set, support inner cabinet manual operation and outer cabinet extension operation, convenient daily maintenance and power cut operation.
✅ Factory Direct Sale & Customization Support
Original manufacturer supply without middleman markup; accept custom current marking, logo printing, packaging and special handle modification for overseas export.
