DRCB4P4A | Circuit Breaker | 4A | 4-Pole | 415V

The DRCB4P4A is a purpose-built industrial circuit breaker designed for reliable protection in 415V, four-pole power systems. With a precise 4A rating, it provides targeted, controlled interruption across all conductors in a 3‑phase setup, helping you maintain safety and uptime in demanding environments.

• Amperage: 4A
• Poles: 4-Pole
• Voltage: 415V
• Configuration benefit: The four-pole design enables simultaneous isolation of all conductors in a 3‑phase system with neutral, enhancing protection during fault or maintenance scenarios.
• Compatibility reference: The part number DRCB4P4A is your best reference for matching this unit to the correct panel or replacement.

This breaker is ideal for maintenance, retrofit, and replacement projects where exact specifications matter. It slots into systems and panels that require a four-pole, 415V protective device and mirrors the performance characteristics of existing DRCB4P4A units, helping minimize downtime and disruption.

Use cases and scenarios

• Replacing aging or failed 4-pole breakers in industrial control panels, MCCs, or distribution boards.
• Retrofitting legacy systems to maintain consistent protection across a 3‑phase circuit with neutral.
• Specifying a like-for-like upgrade when upgrading electrical infrastructure that operates at 415V three-phase power.

Compatibility and installation notes

• Always confirm fit and ratings before ordering to avoid mismatches with your panel or busbar configuration.
• Use the part number as the primary reference when cross-checking compatibility with existing equipment.
• Ensure your system operates at or below 415V and supports a four-pole protective device for proper operation.
• Follow standard electrical safety practices during installation or replacement to protect personnel and equipment.

Who needs this part? Electrical professionals, panel builders, OEMs, and service engineers working with industrial power distribution will appreciate having a true, like-for-like replacement that aligns with existing specifications and field experience. If you’re maintaining or upgrading 4-pole, 415V protection, the DRCB4P4A delivers a precise, dependable solution that keeps critical equipment safeguarded and ready for production.
