Product details

Under UL 1077 / CSA C22.2 No.235 it carries a 5 kA interrupting rating, so for North American panels that's the number to design around. The 50 A rating derates with ambient temperature: 47 A at 40 °C, 45.45 A at 45 °C, 43.8 A at 50 °C, 42.1 A at 55 °C — useful if the breaker sits in a warm enclosure. The terminals accept combined top/bottom wiring, and the breaker is sealable for tamper-proof installations.

At 54 mm wide (3 MW), it fits a standard DIN-rail footprint. The 76 mm depth clears most enclosures, but check gland-plate clearance if the panel is shallow.

Compliance and approvals

Approved under EN 60898 (6 kA) and UL 1077 / CSA C22.2 No.235 (5 kA). The part is halogen-free and silicon-free — relevant for clean-room or sensitive electronics environments. Vibration resistance per IEC 60068-2-6: ±1 mm at 5 to 25 Hz, 50 m/s² at 25 to 150 Hz. Ambient humidity limits: 95% up to 55 °C, 55% up to 70 °C, 35% up to 75 °C.
