DRCB4P20A | Circuit Breaker | 20A | 4-Pole | 415V

The DRCB4P20A circuit breaker is a purpose-built solution for industrial panels and switchgear, delivering reliable protection for 4 electrical poles at a 20A rating and 415V. Designed for maintenance, retrofit, and replacement projects, this unit plugs into systems that require a precise, compatible part number reference and stable, predictable protection across all phases.

Key specifications at a glance

• Amperage: 20A
• Poles: 4-Pole configuration for synchronized phase protection
• Voltage: 415V, suitable for standard three-phase distribution in industrial settings
• Application: Ideal for replacement, retrofit, and maintenance where the DRCB4P20A spec is required

What makes the DRCB4P20A stand out is its ability to disconnect all relevant conductors simultaneously, ensuring safe servicing and reliable motor and circuit protection in demanding environments. The 4-pole design supports complete isolation of multi-phase feeders, which is essential for safe maintenance and compliant shutdowns in equipment like motors, conveyors, and processing lines that run on 415V three-phase power.

Why this 4-pole, 415V breaker matters for your operation

• : By addressing all four poles together, you minimize the risk of residual voltage on any phase during service, enhancing safety and reducing downtime.
• : The 415V rating aligns with common regional and industry voltage levels, helping you avoid compatibility issues during retrofit or panel upgrades.
• : When you need to swap like-for-like, referencing the DRCB4P20A part number ensures the closest match in mounting, terminals, and electrical characteristics.
• : Built for rugged environments, this breaker supports routine protection checks, fault isolation, and predictable tripping behavior that technicians rely on.

Ideal use cases and applications

• Retrofit projects in existing switchgear where a 4-pole, 20A protection device is required for 415V three-phase systems
• Panel board upgrades and replacements in manufacturing lines, processing plants, and utility rooms
• Motor control centers (MCCs) and feeder circuits needing reliable, synchronized disconnects across all phases
• Preventive maintenance workflows that demand clear safety isolation and quick restoration of service

Installation and compatibility tips

To ensure the best outcome, verify fit and ratings before ordering. The DRCB4P20A is easiest to substitute when the replacement matches the exact part number, ensuring terminal layout and mounting compatibility with your existing enclosure. If your system uses 415V three-phase distribution and requires simultaneous phase disconnection, this 4-pole design is a natural fit.

Practical guidance for maximized reliability

• Schedule periodic inspection of terminals and mounting hardware to maintain solid electrical connections
• Confirm that downstream devices (cables, bus bars, and connectors) are rated for 415V and the expected fault current in your facility
• Track replacement against your maintenance cycle and keep the exact part number (DRCB4P20A) as the reference for future orders

For professionals seeking a dependable, industry-aligned circuit breaker that aligns with standard 415V, 4-pole, 20A requirements, the DRCB4P20A delivers clear advantages in safety, maintenance efficiency, and retrofit accuracy. Use the part number as your compatibility compass, and you’ll streamline replacements without guesswork while keeping critical circuits protected.
