4. Protection performance

3‑stage current limiting: Quickly limits peak current during short circuit, reduces thermal stress, protects equipment and cables.

Selective protection: Coordinates with upstream breakers for selective tripping, limits fault area.

Fault indication: Red window shows tripped status for quick diagnosis.

2. Structural advantages

Dual‑lock clip: Secures firmly on DIN rail, prevents vibration loosening.

Quick make mechanism: Improves closing speed, reduces arcing, extends life.

Модульная конструкция: Accepts auxiliary contacts, контакты сигнализации, shunt trip, undervoltage trip, и т. д..

3. Safety design

Функция изоляции: Safe isolation distance in OFF position, meets electrical safety rules.

Anti‑misoperation: Handle design prevents accidental closing.

Flame‑retardant housing: V0 grade material improves cabinet safety.

4. Установка & Обслуживание

Installation Rules

1. Mount vertically (±15°) for proper tripping.
2. Электропроводка: Copper 1.5~35mm², Aluminium 2.5~35mm², torque 1.2~4N·m (depends on cross‑section).
3. Среда: Avoid damp, пыльный, corrosive or high‑vibration locations.
4. Spacing: Maintain clearance for heat dissipation; follow installation manual.

Maintenance Guide

Поиск неисправностей

1. Frequent tripping: Check overload → short circuit → high ambient temperature → aging.
2. Cannot close: Check short circuit → handle position → trip reset → loose wiring.
3. Overheating: Check terminal torque → overload → ventilation.
4. Обновление & Замена
