MJL36500 - 500 Amp Circuit Breaker

MJL36500 - 500 Amp Circuit Breaker

When you’re looking for a high-performance circuit breaker that can keep your critical electrical system safe and running smoothly, the MJL36500 from Schneider Electric’s PowerPacT M-Frame line is engineered to deliver. Rated at 500 A and designed for a 3-pole configuration at up to 600 VAC, this unit offers a formidable 25 kA interrupting rating at 600 V (with higher ratings at lower voltages) to protect against short-circuits and overloads. Its durable construction, advanced electronic trip unit (ET 1.0), and built-in lugs on both line and load sides make it a versatile solution for modern commercial and industrial installations.

Key Features and Benefits

• High-Capacity Protection: With a 500 A rating and a 25 kA interrupting capacity at 600 VAC (and higher ratings such as 65 kA @ 480 V, 100 kA @ 240 V) you get dependable protection for demanding environments.
• Advanced Electronic Trip Unit (ET 1.0): The built-in ET 1.0 unit gives you long-time and instantaneous trip functions with solid-state accuracy, improving fault detection and system management.
• Flexible Mounting & Connection: Unit-mount design with lugs on both line and load sides simplifies installation and allows easier integration into both new and existing panels.
• Wide Operating Temperature Range: Rated for ambient air-temperatures from -25 °C to +70 °C (-13 °F to +158 °F) so the breaker is built for harsh or variable environment conditions.
• Global Safety & Performance Compliance: Meets UL 489, IEC 60947-2, CSA, NOM and other major standards – giving you confidence in worldwide installations.
