JJL36175 - 175 Amp Circuit Breaker

JJL36175 - 175 Amp Circuit Breaker

When you need dependable protection for critical electrical systems, the JJL36175 from Schneider Electric’s PowerPacT J series delivers. This 175 A, 3-pole molded-case circuit breaker is engineered for heavy-duty commercial and industrial environments, providing high-capacity interruption and long-term operational reliability. With a 600 V AC rating, 25 kA breaking capacity at that voltage, thermal-magnetic trip functionality, and unit-mount lug connections, it brings peace of mind — especially when your facility can’t afford downtime or under-performance. It’s built for installers and maintenance teams who demand quality, flexibility and global compliance in one package.

Key Features and Benefits

• High fault-interruption capability: rated at 25 kA when used at 600 V AC, giving you strong short-circuit protection.
• Thermal-magnetic trip protection: precisely senses overloads and short-circuit conditions to reduce risk of damage to wiring and equipment.
• Unit-mount lug installation: simplifies panel layouts and makes replacement or upgrade quicker and more straightforward.
• Field-installable accessories: tailor the breaker to your system’s needs without stocking dozens of variants.
• Global standard compliance: UL 489, CSA, IEC 60947-2 and CE-marked — ensures international acceptance and regulatory peace of mind.
• Environmentally-aware build: comes from a manufacturer with recycled-cardboard packaging and carbon-footprint transparency.
• Wide ambient and altitude ratings: works in harsh conditions (-25 °C to 70 °C operation, up to 2 000 m altitude without derating) so you can count on it in challenging environments.
