• The ONESTO KCM-N Series 2 Pole Din Rail Isolator provides a reliable and secure method for manually disconnecting two-pole electrical circuits.
• Designed for easy DIN rail installation, these isolators are essential for ensuring safety during maintenance, repairs, or in emergency situations in domestic, commercial, and industrial settings.
• Available in a range of current ratings from 32A to 125A, they offer robust performance and a clear visual indication of circuit isolation, disconnecting both live and neutral, or two phases, simultaneously.

Features

• Double Pole (2P) configuration for isolating two conductors simultaneously.
• Available current ratings: 32A, 63A, 80A, 100A, 125A.
• Standard DIN rail mounting for convenient installation.
• Complies with IEC/EN 60947-1 and IEC/EN 60947-3 standards.
• The 32A model (KCM-N-232) specifically notes SABS in accordance to IEC 60947-2.
• Rated operational voltage (Ue) of 240V/415V AC.
• Rated insulation voltage (Ui) of 500V.
• High rated impulse withstand voltage (Uimp) of 6kV.
• Suitable for 50/60Hz electrical systems.
• IP20 protection rating.

Benefits

• Complete Circuit Isolation: The 2-pole design ensures both relevant conductors (e.g., live and neutral, or two phases) are disconnected, offering enhanced safety and preventing accidental energization.
• Broad Application Range: With current ratings from 32A up to 125A, these isolators cater to a wide variety of circuit requirements in different installations.
• Effortless Installation: Compatibility with standard DIN rails simplifies mounting in electrical panels, distribution boards, and enclosures.
• Guaranteed Safety and Quality: Adherence to international (IEC/EN 60947 series) and relevant local standards (SABS for specific models) ensures product reliability and safe operation.
• Superior Durability: A 6kV rated impulse withstand voltage protects the isolator against transient overvoltages, enhancing its longevity and operational stability.
• Enhanced User Safety: The IP20 rating provides protection against finger contact with live internal parts when correctly installed within an enclosure.
• Unambiguous Disconnection: Provides a clear and positive break in the circuit, giving unequivocal visual confirmation that the circuit is safely isolated.

Technical Specifications

Ideal Use

• Main incoming power isolation for single-phase (Live + Neutral) or two-phase supplies in residential, commercial, or light industrial applications.
• Isolation of dual-pole circuits for equipment like larger appliances, HVAC systems, or specific machinery.
• Use in distribution boards for isolating specific sections or two-pole loads.
• Applications where simultaneous disconnection of two conductors is critical for safety and maintenance.
• Installations requiring a lockable point of isolation (check if lockable accessory is available or integral).

Tips

• Verify Amperage Needs: Ensure the selected isolator's current rating is appropriate for the circuit's maximum continuous load and not less than any upstream protective device.
• Upstream Overcurrent Protection: Remember that isolators are for disconnection only and do not typically provide overcurrent protection. Ensure the circuit is protected by suitable MCBs or fuses upstream.
• Professional Installation Required: Installation should always be carried out by a qualified and certified electrician, adhering to all local electrical regulations and safety standards.
• Secure Terminal Connections: All electrical connections must be tightened to the manufacturer's recommended torque settings to prevent overheating, arcing, and potential fire hazards.
• Routine Checks: Periodically inspect the isolator for any physical damage, signs of overheating (discoloration), or loose connections. Verify smooth mechanical operation.
• Clear Circuit Identification: Properly label the isolator to clearly indicate which circuit it controls. This is crucial for safe operation, especially during emergency or maintenance procedures.
