Features and benefits:

• 1P+N design - simultaneously breaks phase and neutral on a single-phase final circuit, ensuring full isolation during maintenance
• Dual standards rated (EN 60898 6 kA / IEC 60947-2 30 kA) - usable in both residential/commercial distribution boards and industrial installations
• UL 1077 5 kA listed - suitable for North American panels as a supplementary protector
• C curve (5-10 x In) - tolerates moderate inrush from inductive and capacitive loads while still protecting cables
• Combined terminals top + bottom - accept comb busbars on top with cable on bottom (or vice versa)
• Sealable handle - prevents unauthorized switching in critical circuits
• Halogen-free and silicon-free housing - suitable for clean room and food/pharma environments
• Main-switch rated per EN 60204-1 - can serve as machine main isolator within its rating

Applications:

• Single-phase lighting and small-power final circuits requiring simultaneous phase + neutral switching
• Commercial and industrial sub-distribution panels protecting 6 A rated loads
• Control panels needing C-curve protection for moderate inrush loads (transformers, small motors, LED drivers)
• Machine builder applications requiring UL 1077 supplementary protection plus EN 60204-1 main switch capability
