Schneider Electric | OSMC65H1D3 | Circuit Breaker | 3A | 1-Pole | 480V

Schneider Electric offers the OSMC65H1D3 Circuit Breaker — a compact, reliable protection device engineered for industrial panels that demand a 1-pole, 480V solution with a precise 3 A rating. Built for maintenance, retrofit, and replacement projects, this breaker ensures consistent overcurrent protection while preserving valuable enclosure space.

Key Specifications

• Amperage: 3 A
• Poles: 1-Pole
• Voltage: 480 V
• Part Number: OSMC65H1D3

Why this model stands out

Designed by Schneider Electric, the OSMC65H1D3 delivers dependable protection for control circuits and low-current loads within higher-voltage systems. Its 1-pole form factor is ideal for compact control panels and spaces where a full-width breaker isn’t feasible. The 480V rating expands its applicability to industrial environments where higher-voltage control circuits are common, while the 3 A rating provides precise protection for delicate loads without nuisance trips.

Ideal use cases

• Maintenance projects that require drop-in replacements with matching specifications
• Retrofits in aging panels where space or current requirements have changed
• Replacements in equipment or control enclosures that operate at up to 480V and need a 3 A protective device

Compatibility and selection tips

For best results, use the part number OSMC65H1D3 as the primary reference when verifying compatibility. Always confirm fit and ratings against your existing panel or enclosure before ordering. If in doubt, cross-check with your panel manufacturer documentation to ensure the breaker’s electrical characteristics align with the system’s design requirements.

Practical guidance for installation and use

• Ensure power is fully de-energized before replacement or installation.
• Verify that the circuit’s voltage, load current, and shutdown requirements align with the 480V, 3 A, 1-Pole specification.
• Follow manufacturer wiring diagrams and local electrical codes for safe mounting and secure terminal connections.
• Keep this unit as a planned spare for proactive maintenance to minimize panel downtime.

Whether you’re maintaining an existing control panel, retrofitting older equipment, or replacing a failed component, the Schneider Electric OSMC65H1D3 delivers reliable, space-saving overcurrent protection with a clear reference point for compatibility. It’s the precise choice for technicians who prioritize correctness, ease of ordering, and long-term panel reliability.
