Circuit breakerTMAX T4N 320 Fixed three-pole with front terminals and solid-state release in AC PR221DS-LS/I R 32.

ABB SACE’s Tmax power circuit-breakers come in five sizes: T1, T2, T3, T4 and T5, able to cover a range of service currents from 1 to 630 A. All the circuit-breakers, both three-pole and four-pole, are available in the fixed version; the sizes T2, T3, T4 and T5 in the plug-in version and T4 and T5 in the withdrawable one as well.

With the same overall dimensions, the circuit-breakers in the Tmax family, are available with different breaking capacities at 380/415 V, indicated by the following letters:

Construction characteristics

• Double insulation: Tmax has double insulation between the live power parts (excluding the terminals) and the front parts of the apparatus where the operator works during normal operation of the installation.
• Isolation behaviour: The operating lever always indicates the precise position of the moving contacts of the circuit-breaker, thereby guaranteeing safe and reliable signals, in compliance with the prescriptions of the IEC 60073 and IEC 60417-2 Standard (I = Closed; O = Open; yellow-green line = Open due to release trip).
• Comportamiento del aislamiento: , the circuit-breaker guarantees circuit isolation in compliance with the IEC 60947-2 Standard.
