MA36600 - 600 Amp Circuit Breaker

MA36600 - 600 Amp Circuit Breaker

When you need industrial-level protection in your electrical system, the MA36600 molded case circuit breaker delivers dependable performance with advanced safety features. Built for demanding environments, this breaker is rated for up to 600 V AC and 600 amps, so it’s ideal for shielding vital circuits from overloads or short circuits. Its design supports integration into I-Line systems, making installation and maintenance much easier in commercial or industrial settings.

Key Features and Benefits

• Durable construction: The case is made from high-quality materials that resist mechanical stress and environmental wear.
• High interrupting capacity: With the ability to interrupt fault currents up to 18 kA at 600 V, it minimizes risk to connected equipment and wiring.
• ET 1.0 electronics: Offers reliable thermal-magnetic protection with fast, precise tripping under fault conditions.
• 80 % continuous current rating: Designed to carry a sustained 80 % of its rating without overheating, giving you room for operational fluctuations.
• I-Line compatibility: Fits seamlessly into I-Line panel layouts, allowing for modular additions or replacements without significant rework.
• Manual trip test: A push-to-trip mechanism enables functional testing without needing a complete fault condition.

These features help reduce system downtime, streamline maintenance, and enhance overall operational safety.
