MAL36500 - 500 Amp Circuit Breaker

MAL36500 - 500 Amp Circuit Breaker

Safeguard your electrical distribution with the MAL36500 molded case circuit breaker. Built for high-demand environments, this 3-pole, 500 A unit reliably protects against overloads and short circuits—so you can focus on uptime, not failures. Rated for up to 600 V, it excels in commercial and industrial settings where heavy currents and fault events are expected. With proven performance and dependable design, the MAL36500 gives you peace of mind and helps ensure continuity of critical power systems.

Key Features and Benefits

• High current handling: 500 A continuous rating accommodates heavy loads with headroom.
• Broad voltage range: Operates up to 600 V (AC), enabling use in multiple voltage systems.
• Feed-through lug design: Line and load lug connections simplify integration into distribution panels.
• Thermal-magnetic trip functionality (LI type): Offers both long-time (overload) and instantaneous (short-circuit) protection in one unit.
• Compact footprint for capacity: Though a high-capacity breaker, its profile is engineered to fit in many panel layouts.
• Trusted brand reliability: Backed by the engineering standards and quality associated with the manufacturer.

Each feature is tailored so you get protection, flexibility, and operational security in demanding installations.

Material Compliance and Certifications

• Environmental / regulatory compliance: Carries the Green Premium™ label, which affirms its alignment with environmental standards and sustainable material policies.
• Certifications / listings: Meets recognized safety standards for molded case circuit breakers (e.g. UL, CSA) in its class.
• California Proposition 65 warning: Contains DINP and DIDP, chemicals identified by California as potential cancer or reproductive hazards. Use proper handling and disposal practices.
• Warranty coverage: Supported by an 18-month warranty from the original manufacturer.

This combination of compliance and warranty gives purchasers confidence in safety, regulation, and support.

Where It Works Best

• Main feeders or secondary distribution in commercial or industrial power systems
• Large motor loads, HVAC systems, or heavy machinery where high current protection is non-negotiable
• Upgrades, retrofits, or expansions where panels have limited space but require high-capacity protection
• Utilities, factories, data centers, and infrastructure projects—any place you need solid overcurrent protection for high-demand electrical circuits
