REF3A005 | Circuit Breaker | 3A | 3-Pole | 600V

REF3A005 is an industrial circuit breaker engineered for reliable overcurrent protection in three-phase electrical systems up to 600 volts. With a compact 3A rating spread across 3 poles, this device is designed for maintenance, retrofit, and replacement projects where exact specifications matter.

Key specifications at a glance:

• Amperage: 3A
• Poles: 3-Pole
• Voltage: 600V
• Reference: Part number REF3A005 (best compatibility reference)

Why this matters in the field

• Three-pole protection is essential for balanced three-phase circuits, helping prevent equipment damage, electrical arcing, and unexpected downtime.
• 600V rating makes it suitable for industrial control panels, machine tools, and power distribution as a drop-in replacement when the specs align.
• Using the exact part number REF3A005 ensures you’re selecting a match for your existing panels and safety certifications.

Use cases and ideal scenarios

• Maintenance events where an existing REF3A005 unit fails or reaches end-of-life
• Retrofit projects updating older control panels to a 3-pole 600V protection scheme
• Replacement in spare-part inventories to reduce downtime with a known, compatible component

Practical tips for safe, effective installation

• Always confirm fit and ratings before ordering to avoid compatibility issues.
• Cross-check the panel’s electrical specifications and terminal configuration against the REF3A005 details.
• Maintain appropriate clearance and follow lockout/tagout procedures during replacement work.
