Industrial L9-15/3/C 15A 3-Pole Circuit Breaker

Meet the Industrial L9-15/3/C 15A 3-Pole Circuit Breaker — a rugged, three-phase protective device designed for demanding industrial panels. With a precise 15-amp current rating and a three-pole configuration, this breaker safeguards your equipment and processes across all three live lines.

Designed for reliable three-phase protection

In three-phase systems, protecting every phase is essential to prevent unbalanced loads, phase faults, and unexpected downtime. The L9-15/3/C interrupts all three conductors simultaneously, delivering coordinated protection for motors, drives, and control circuits in manufacturing floors, warehouses, and facilities.

Key features

• Current rating: 15 A
• Poles: 3
• Part Number: L9-15/3/C
• Industrial-grade construction: robust housing designed for enclosure mounting and frequent operation
• Quick installation: standard mounting compatible with common control panels
• Protective action: provides overload and short-circuit protection across all three phases

Ideal use cases

Commonly deployed in:

• Three-phase motor circuits in conveyors, pumps, and machine tools
• Industrial control panels for automation, HVAC, and processing equipment
• Power distribution boards in manufacturing, facilities management, and logistics environments

How it stacks up against alternatives

Compared to single-pole devices, the L9-15/3/C ensures simultaneous interruption of all conductors in a three-phase system, reducing the risk of phase-induced damage and simplifying panel protection alignment. Its compact footprint makes it a practical fit where space and reliability are critical.

Practical installation tips

• Confirm compatibility with your panel’s mounting style and bus configuration before purchase.
• Plan for proper wiring routes and strain relief to sustain performance in industrial environments.
• Document the part number (L9-15/3/C) in your asset management system for easy replacement and compliance checks.

Choose the Industrial L9-15/3/C 15A 3-Pole Circuit Breaker for dependable three-phase protection that helps minimize downtime and protect valuable equipment in your operation.
