Features and benefits:

• C curve thermal-magnetic trip unit provides reliable protection against overloads and short circuits in distribution circuits with moderate inrush currents.
• 3000A breaking capacity at 230V AC meets IEC/EN 60898-1 requirements for residential and light commercial distribution boards.
• Plug-in top connection and tunnel-type bottom terminals accept conductors from 1 to 25 mm² rigid, simplifying installation and wiring flexibility.
• Clip-on DIN rail mounting with 4 x 9 mm pitch allows compact panel assembly and easy integration alongside other Resi9 modular devices.
• Operating range of -25 to 40°C and tropicalisation class 2 (IEC 60068-1) ensure reliable performance across varied environmental conditions.
• ON/OFF toggle indication provides clear local status signalling for safe operation and maintenance.

Applications:

• Final distribution boards in residential buildings requiring 2-pole overcurrent protection on 230V AC circuits.
• Light commercial installations where C curve characteristics suit loads with moderate inrush, such as lighting and general socket circuits.
• Modular enclosure assemblies requiring compact DIN rail-mounted protection devices alongside RCDs or other Resi9 accessories.
• Sub-distribution panels in small commercial or industrial premises operating on single-phase 230V AC networks.
