Overview
The Square D 60163 is a Multi 9 C60 miniature circuit breaker designed for industrial branch circuit protection. This 2-pole, 15A unit features a D-curve thermal magnetic trip characteristic and is rated for 240 VAC at 10 kA interrupting capacity. The Square D 60163 combines reliable overload and short-circuit protection with modular DIN rail mounting in a compact footprint ideal for control panels and distribution equipment.
Key Features
- D-Curve Trip Characteristic: Designed for standard resistive and inductive loads with moderate inrush currents, reducing nuisance tripping
- UL 489 / CSA C22.2 No. 5 Listed: Certified for branch circuit protection and industrial automation applications
- Compact Modular Design: Single 0.35-inch (9 mm) module per pole mounts on standard 35 mm DIN rail
- Box Lug Terminal Connections: Pressure-plate terminals accept copper wire up to #2 AWG for reliable field connections
- High Endurance: 20,000 mechanical operation cycles and 10,000 electrical cycles for long service life
- Reverse Feeding Capable: Permits reverse-feeding of line power when required by system design
