Cutler Hammer SPCL1C05 - 5A, 1-Pole, Circuit Breaker

The Cutler Hammer SPCL1C05 is a compact, reliable 5A, 1-pole circuit breaker engineered to deliver precise overcurrent protection where it matters most. Built for industrial and commercial environments, this unit integrates smoothly into panelboards, switchboards, and control panels, helping keep equipment and operators safe while reducing downtime.

Why the SPCL1C05 stands out

• Targeted protection for low-current circuits — a 5-amp rating makes it ideal for control circuits, signaling lines, and small auxiliary loads where stronger breakers would cause nuisance trips.
• 1-pole simplicity — streamlined wiring and a compact footprint simplify panel design and layout, saving valuable space in dense control cabinets and switchgear.
• Dependable, steady performance — designed by Cutler Hammer to deliver consistent trip behavior and safe operation in everyday use within distribution panels and motor control centers.
• OEM-friendly integration — a straightforward, plug-and-play option that fits standard panelboard configurations, helping streamline upgrades and replacements in existing systems.
• Rugged for industrial environments — built to endure the demands of commercial and manufacturing settings where dependable protection is essential.

Ideal applications

• Distribution panels in manufacturing lines requiring dedicated protection for control circuits and low-load feeders.
• Motor control centers and equipment enclosures where compact, reliable overcurrent protection is needed.
• OEM equipment and machine control panels that demand precise trip thresholds to safeguard sensors, relays, and automation components.

Key specifications

• Current rating: 5A
• Poles: 1-Pole
• Breaker type: Circuit Breaker

Practical guidance for use

When selecting the SPCL1C05, align the breaker's 5A rating with the protected circuit’s load and fault tolerance to ensure reliable operation without unnecessary interruptions. Verify that the single-pole configuration matches your panel’s slotting and wiring plan, and consider this unit as a first-choice replacement for aging control-circuit breakers in OEM or retrofit projects. For installation, ensure secure seating in the panelboard and proper termination of conductors to maintain a clean, dependable electrical system.
