Onesto 1P Isolator DIN

• The ONESTO KCM-N Series 1 Pole Din Rail Isolator is an essential safety device designed for reliable manual isolation of single-phase electrical circuits.
• Engineered for straightforward DIN rail mounting, these isolators are crucial for maintenance, repair operations, or emergency shutdowns in domestic, commercial, and industrial environments.
• This range, specifically covering 32A, 63A, 80A, and 100A ratings, offers robust performance and ensures circuits can be safely de-energized, providing a clear and visible point of disconnection.

Features

• Single Pole (1P) configuration for isolating one phase.

• Available current ratings: 32A, 63A, 80A, 100A.

• Designed for standard DIN rail mounting.

• Complies with IEC/EN 60947-1 and IEC/EN 60947-3 standards (KCM-N-132 also 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 for enhanced safety.

Benefits

• Enhanced Safety: Provides a secure and visible means to manually disconnect a circuit from the power supply, vital for preventing electrical shock during maintenance or servicing.

• Application Versatility: The range of current ratings (32A, 63A, 80A, 100A) makes these isolators suitable for a broad spectrum of loads and applications.

• Simplified Installation: Standard DIN rail compatibility allows for quick, easy, and secure installation in common electrical panels and distribution boards.

• Assured Reliability: Conformance to international standards (IEC/EN 60947 series) guarantees product quality, operational safety, and consistent performance.

• Increased Durability: With a 6kV rated impulse withstand voltage, the isolator is protected against transient voltage spikes, contributing to a longer service life.

• Operator Protection: The IP20 rating offers protection against accidental finger contact with live parts when the device is installed in an enclosure.

• Clear Circuit Status: Offers a definite break in the circuit, giving unambiguous visual confirmation that the circuit is isolated.

Technical Specifications

Ideal Use

• Main incoming power isolation for residential properties or small commercial units.
• Isolation of individual circuits or appliances for maintenance, such as air conditioning units, water heaters, or machinery.
• Use in sub-distribution boards to isolate sections of an electrical installation.
• Suitable for domestic, commercial (e.g., retail stores, offices), and light industrial installations.
• Applications requiring a clear and lockable point of electrical isolation for safety procedures (lockout/tagout).

Tips

• Select Appropriate Rating: Always choose an isolator with a current rating that is equal to or greater than the maximum continuous current of the circuit it will isolate, and not less than any upstream protective device rating.
• Ensure Upstream Protection: Isolators provide a means of disconnection but generally do not offer overcurrent protection. Ensure the circuit is adequately protected by an upstream MCB or fuse.
• Qualified Installation: Installation must be performed by a certified electrician in compliance with all relevant local electrical codes and safety standards.
• Secure Connections: Properly tighten all terminal connections to the manufacturer's recommended torque specifications to avoid overheating and potential hazards.
• Regular Inspection: Periodically check the isolator for any signs of damage, overheating, or loose connections, and ensure the mechanical operation is smooth.
• Clear Labeling: Clearly label the isolator to identify the circuit it controls, facilitating safe and efficient operation, especially during emergencies or maintenance.
