• Poles: 3-Pole
• Voltage: 36800 V
• Part reference: MAP36800V

Why this MAP36800V matters in your system

In high‑voltage, three‑phase environments, reliable protection is non‑negotiable. The MAP36800V from Square D is engineered to interrupt fault currents quickly and safely, helping to safeguard transformers, feeders, and switchgear assemblies. Its 800 A rating is designed to handle substantial load profiles, while the 3‑pole configuration ensures balanced protection across all three phases. When downtime is costly, you want a breaker with a track record of consistent performance under demanding conditions.

Ideal for

• Industrial plants and process facilities with 3‑phase power distribution
• Retrofit projects where exact compatibility with existing gear is essential
• Maintenance and replacement work that requires matching ratings to prevent system disruption

Use cases and scenarios

• Replacing a failed high‑voltage breaker in a legacy switchgear lineup while preserving original electrical characteristics
• Upgrading an aging protection scheme to a unit that supports 36.8 kV service without altering downstream equipment
• Integrating into a new or refurbished 3‑phase distribution path where robust fault containment is critical

Fit, compatibility, and ordering notes

Before you order, confirm fit and ratings against your system’s nameplate and documentation. The MAP36800V model number is the most reliable reference for compatibility, ensuring the breaker aligns with your panel, switchgear, and protection scheme. If you’re replacing an existing unit, verify that the original equipment uses the same voltage class (36.8 kV) and the same three‑pole configuration to maintain protection coverage and coordination.

Practical tips for installation and operation

• Engage a qualified electrical professional for high‑voltage installations to ensure proper torque, alignment, and busbar connections.
• Verify that the breaker’s interrupting rating matches the system fault current to maintain protective coordination.
• Keep detailed records of the part number (MAP36800V) and installation date for future maintenance and replacements.

With the Square D MAP36800V, you gain a purpose‑built solution that pairs precise high‑voltage protection with dependable performance. It’s the deliberate choice for professionals who value exact specifications, clear compatibility, and durable protection in demanding industrial environments.
