• High breaking capacity of 10 kA at 230 V AC makes it suitable for demanding distribution applications.
• C tripping curve provides reliable protection for resistive and slightly inductive loads with higher inrush tolerance.
• Compatible with comb busbar distribution blocks on both top and bottom terminals for flexible panel wiring.
• Trip position indicator and toggle handle allow quick local status identification and manual operation.
• Wide operating temperature range (-35 to 70 °C) supports use in both indoor and harsh environment enclosures.
• Limitation class 3 reduces let-through energy, providing enhanced protection for downstream equipment.

Applications:

• Final distribution boards in residential and light commercial electrical installations.
• Protection of branch circuits in industrial control panels and automation cabinets.
• Circuit protection in DC power distribution systems (up to 72 V DC).
• Electrical energy distribution in switchboards where high breaking capacity is required.
