Overview
The Schneider Electric 60179 Multi 9 C60 is a three-pole miniature circuit breaker designed for industrial control and distribution applications. This UL 489-listed MCB combines reliable overload and short-circuit protection in a compact form factor suitable for DIN-rail installation in control cabinets and panel enclosures.
Key Features
- Three-pole configuration for balanced three-phase protection
- C-curve tripping characteristic (5–10× rated current) for typical industrial loads
- Trip-free mechanism prevents manual override during fault condition
- Toggle actuator with distinct on/off/tripped positions
- Clip-on DIN-rail mounting for fast, tool-free installation
- Compact size and lightweight design for space-constrained panels
Technical Specifications
The 60179 delivers thermal-magnetic protection with a 10 kA asymmetric interrupt rating (AIR). Wire compatibility spans 18 AWG through 4 AWG, with insulated terminals rated IP20 and an IP40 case rating. This breaker operates reliably across industrial temperature ranges and meets multiple international standards for low-voltage circuit protection.
Typical Applications
- Three-phase motor control and distribution panels
- Industrial automation and PLC systems
- Manufacturing equipment and machinery protection
- HVAC and water pump systems
- Backup power and UPS systems
- General-purpose industrial control cabinets
