Industrial 3DU13 Circuit Breaker

Altech Corp's 3DU13L is a three-pole UL 489 miniature molded‑case circuit breaker built for DIN‑rail mounted protection in industrial control panels. This 13 A device from the 3DUxL family provides UL 489‑rated branch‑circuit protection and is designed for compact installation with a width of 17.5 mm per pole (three poles ≈ 52.5 mm total). The unit is listed to UL 489, UL 508, and UL 1077 protection schemes, reflecting its versatility for branch protection, control circuits, and auxiliary protection in mixed electrical environments. Typical applications include three‑phase distribution panels, machine enclosures, and control panels where reliable protection and easy DIN rail mounting are required. The 3DU13L is offered in standard packs of four, and weighs about 1.7 kg, making it suitable for panel layouts that balance protection with mechanical stability. As with other Altech UL Series breakers, it supports a range of trip profiles consistent with UL 489 devices, helping ensure predictable interruption behavior under overload or short‑circuit conditions.
