Manual isolator switch

3-poleACthree-phase

Overview
The KINRED three-pole isolator switch is designed to safely disconnect and isolate three-phase circuits for maintenance or emergency shutdowns. The device provides positive isolation via three independent poles and is operated by a single handle for clear ON/OFF switching. Multiple pole variants (SP, DP, TP, FP) and compact DIN-rail mounting enable flexible integration into control panels and distribution boards.

Advantages

• Provides secure electrical isolation for maintenance and emergency procedures
• Fast, unambiguous manual operation with a single handle (ON/OFF)
• Available in multiple current ratings to match application needs (40 A, 63 A, 100 A)
• Compact DIN-rail footprint for efficient panel layout
• Supports compliance with electrical safety regulations

Typical Uses

• HVAC and building services
