CBI Isolator 63A 2P 6kA D/M

• The CBI Electric QF(13)-S series offers a line of ultra-compact, DIN rail mountable switch disconnectors (isolators) rated at 63 Amps.
• Available in 1-pole (QFA10063), 2-pole (QFA20063), 3-pole (QFA30063), and 4-pole (QFA40063, typically 3P+N) configurations, these devices provide reliable manual switching and safe isolation for AC circuits.
• Based on the space-saving 13mm-per-pole QF(13) platform with a standard black shell, they comply with SANS 60947-3 and IEC/EN 60947-3 for switch disconnectors.
• Featuring high mechanical endurance and clear ON/OFF indication, the QF(13)-S isolators are ideal as main switches or local isolation points in distribution boards and control panels where separate overcurrent protection is provided upstream. 
• These devices are isolators ONLY and do NOT provide automatic circuit protection.

Benefits

• Compliant Isolation: Meets specific standards for switch disconnectors, ensuring safe isolation for maintenance.

• Maximum Space Efficiency: Ultra-slim 13mm per pole design allows for very high-density DIN rail and Mini rail Panels.

• Reliable Manual Switching: Dependable mechanism for manually operating circuits up to 63A.

• Clear Status Indication: Handle position and LED clearly show the isolator's state.

• Standardized Mounting: Easily integrates into standard DIN rail based enclosures and panels.

• Robust Construction: Designed for long operational life in industrial and commercial settings.

• Consistent Rating: 63A rating across all pole configurations simplifies specification.

Technical Specifications

 Ideal Use

• Main Isolator: Used as the primary disconnect switch on DIN rail distribution boards (upstream of branch circuit breakers).

• Local Equipment Isolation: Providing a safe, lockable point of isolation for single or multi-phase machinery/equipment during maintenance.

• Load Switching: Manually controlling circuits up to 63A where automatic overcurrent protection is not required at that point.

• Panel Building: High-density industrial and commercial panels requiring SANS 60947-3 compliant isolation.

Tips

• Isolator Function ONLY: This device does not trip automatically on overload or short circuit. It MUST be protected by an upstream fuse or MCB rated appropriately for the circuit.

• Standard Compliance: Ensure SANS 60947-3 / IEC 60947-3 compliance is suitable for the specific application requirements.

• Voltage Rating: Use 1P/2P for 240V systems, 3P/4P for 415V systems.

• Short-time Rating: The 6kA Icw rating indicates its ability to withstand fault current for a short duration when protected by a suitable upstream device. It's not an interrupting rating.

• Wiring: Connect circuits according to the pole configuration required (1P, 2P L+N/L1+L2, 3P L1/L2/L3, 4P L1/L2/L3+N). Torque terminals to 2.5 Nm.

• Mounting: Designed for Dual Mount (D/M) applications DIN and Mini Rail.
